What is WAN blocking?
It’s a process that prevents the transmission of data over Internet Protocol (IP) networks. It occurs when there are too many packets to be transmitted at once, and it can lead to significant delays in network performance.
WAN blockers work by slowing down traffic on one or more computers within the network, which forces all other traffic to slow down as well. These devices usually operate on layer 2 of the OSI model, which means they filter out unwanted transmissions before they reach layer 3 (the networking part). This way, only those packets with a destination address matching the blockers will be allowed through. The net result is that less bandwidth is available for use by anyone else who might need it.
What is WAN blocking?
WAN blocking is a type of internet censorship that is employed by the government or an ISP to block certain content. The term “WAN” stands for Wide Area Network and this type of censorship is used to prevent access to websites and other content from outside sources. Typically, these blocks are imposed on Internet Service Providers and other service providers and they work by inspecting the packets and looking at the address information in them.
WAN blocking can be done either through domain name system (DNS) filtering or packet filtering techniques. With DNS filtering, the ISP looks up all packets that are coming in for IP addresses and filters them by their domain name. Packet filtering is when packets are looked at to see what protocol they carry, where they come from, and where they are going. If the traffic matches certain criteria set up by the internet service provider or government agency, then the packets are dropped or blocked completely.
How many types of WAN blocking are there?
There are 3 different types of WAN blocking: IP blocking, MAC address filtering, and IP Address Filtering.
IP blocking is a form of WAN blocking that targets a specific device by looking at its IP address. In order to block a device, the system administrator must determine that device’s IP address and then add it to a list. During this process, the administrator will also select how long that device is to be blocked. This could be anywhere from 1 minute up to several hours or even indefinitely.
MAC address filtering is another form of WAN blocking that allows a system administrator to block a device by looking at its MAC address. In order to do this, the administrator must first input the MAC addresses of all devices allowed on the network as well as those which are not allowed. The blocking will take place based on whichever category the device falls into. If the device is not in that category, it will be allowed access to the network.
The last form of WAN blocking is IP address filtering, which can block an IP address from accessing a network by looking at its IP address. During this process, the administrator must also input how long it should be blocked for or whether or not a specific time should be used instead. If it is to be blocked indefinitely, the administrator will have to manually unblock it for as long as they desire.
Why would any company need to use it?
A company might want to use this technology for security reasons. For example, if people are using the wifi for the internet, there may be malware on the network that could harm an organization’s system.
If a user is in a sensitive area of the network, they might not want other users on the same wifi to see what they are doing. It’s also important to note that many companies don’t allow access from outside the internet during business hours. If it turns out a user isn’t using the company wifi when they should be, it helps them enforce that rule.
An organization may not want sensitive documents being sent out or received during business hours. If there are employees that need to have access outside of normal working hours, blocking WAN traffic can help allow them to do so while still maintaining security for the rest of the organization.
When should I use it?
There are two times in which you would use a WAN block:
1) For protection against hackers- when networks are linked to the Internet, they are vulnerable to attacks by hackers. As the networks are much more vulnerable, WAN blocking is used to provide protection.
2) To throttle bandwidth for an individual- LAN users may also be able to benefit from the use of this function. This is because it can help control usage when there are many people in one location or office.
Conclusion
WAN blocking is a technique that prevents people from accessing websites, applications, and other content on your network. WAN blocking can be useful for companies who want to block specific sites or apps during certain hours of the day or week. In some cases, an organization might need to do this in order to comply with laws such as COPPA (Children’s Online Privacy Protection Act) which requires parental consent before collecting personal data from children under 13 years old. Some organizations believe they may have legitimate reasons for needing to prohibit access outside their physical location using WAN blocking techniques so employees are more productive at work. WAN blocking is not the same as WAN optimization, but it can be combined with WAN optimization.
Router WAN Blocking: Safe to Enable?
Here’s whether you need to enable WAN blocking on your router:
When you enable port forwarding (turn off WAN blocking), you allow the entire Internet to potentially redirect to one of the internal IP addresses of your LAN.
If you’re not running servers from your home and want maximum security, you don’t need to enable external WAN access and should enable WAN blocking.
If you want to learn all about why you should enable WAN blocking and what WAN blocking is, then you’re in the right place.
So without further ado, let’s do this!
Do You Need to Enable WAN Blocking on Your Router?
The internet can be a confusing place.
Just a quick google search of any term related to the internet yields hundreds of thousands of results.
Indeed, each aspect of the internet seems to, upon closer inspection, give birth to many more terms that one must learn before one fully understands the issue.
Perhaps you’ve seen the WAN blocking setting on a new router and are curious about whether or not you should enable WAN blocking? Perhaps you’re not even sure what this means.
The short answer is this: yes, in most cases, the person reading this article should enable WAN blocking.
To find out why you should read this article.
Below you’ll find your comprehensive WAN guide:
- What is WAN
- Why you should enable WAN blocking
- Basically everything related
What Is WAN on Your Router?
First things first: we need to define our first variable.
WAN is short for Wide Area Network.
A network is by definition any connection of two or more computers linked together to share utilities such as printers or to share resources such as files and otherwise communicate electronically.
A WAN is one of two basic kinds of networks that computers can be a part of. It contrasts with LAN, which is short for Local Area Network.
What Is the Difference Between WAN and LAN?
A WAN is a large network (hence the term “wide”) that is quite common amongst large corporate entities, universities, and other organizations that need to connect many computers over a large geographic range.
WANs are broad-area computer networks. For instance, any network that crosses regional and metropolitan boundaries over a great distance.
A LAN, meanwhile, is (as the word “local” implies) limited to a smaller geographic range. LANs are computer networks that cover a small geographic area, such as a house, office, or building complex.
LAN Connection
The most typical LAN is found in an individual’s home: imagine a small family with multiple computers and only one printer.
Connecting these computers together in a network so that each member of the family can use the same printer will not only seem very handy; connecting to the home printer will likely be a basic household requirement for this family.
When this family connects their computers to their printer, they have just formed a basic LAN.
A LAN can be larger, however. Many regional offices with a relatively small number of employees are connected via LAN.
Computers on a LAN can be connected by being wired directly together, or they can be connected wirelessly via WAPs (Wireless Access Points). Let’s don’t go into that here, but you can think of your router as your local WAP.
WAN Connection
If a LAN is a connection of multiple computers to form a network, we can (in most cases) think of a WAN as a connection of LANs together in one large network.
What Are the Advantages of a WAN Network Connection?
Connecting LANs together to form a WAN network has a variety of obvious advantages for large organizations.
For example, imagine you are the head of HR for a multinational corporation.
You have a series of training modules that you want to be implemented uniformly across the corporation to maintain a certain standard in workplace comportment.
With a WAN, you can store these training modules on a centralized node that is easily accessible by all computers on the WAN.
Each employee, meanwhile, may simultaneously be operating on their regional office’s LAN.
What Are the Disadvantages of a WAN Network Connection?
A WAN network sounds like a great thing; you might be thinking to yourself.
Well, that’s the truth! It is! But it’s also less secure.
Allowing a larger group of people to access the network means there are more access points for hackers and other ne’er-do-wells.
Now, that’s not to say that you can write off WANs completely. Believe it or not, you’re on a WAN right now.
How Is WAN Related to the Internet?
Here’s the deal. The internet is actually the largest WAN network in the world.
Most routers have a single WAN port to allow for the exterior internet connection and multiple LAN ports to hook up home computers.
Your router will, in turn, connect to a broadband modem that will connect you to the internet.
You can think of it this way: the router routes all LAN traffic to the internet. Most internet service providers (ISP) these days will, however, provide a single device that is a router-modem combo.
The broadband modem will be connected by either a telephone port or coaxial port to allow your LAN to access all of the great treasures stored on the WAN of the internet.
To Enable or Not to Enable WAN?
So, now we come to the crux of the issue. Should you enable WAN blocking on your computer?
Well, let’s first take a look at what WAN blocking actually is.
What is WAN Blocking?
Most routers provided by ISPs will come default set to block WAN traffic to your LAN. In essence, WAN blocking keeps external internet traffic from entering your LAN.
When you open up port forwarding (disable WAN blocking), YOU ALLOW THE ENTIRE INTERNET to potentially redirect itself to one of the internal IP addresses of your LAN.
Allowing the internet to access your local area network gives them access to your router’s GUI (Graphic User Interface) or online settings, as well as its ICMP: Internet Router Discovery Protocol.
The ICMP is the protocol whereby your computer accesses the internet via the router.
Access to the ICMP would allow an internet vagrant to use your router to reconnect themselves to the internet.
In addition, many routers use NAT (Network Address Translation), otherwise known as “masquerading.”
So, What is NAT “Masquerading?”
With NAT, your router connects to the internet and acts like every computer on your LAN is the exact same IP address (let’s not cover IP addresses here, but you can check those out here).
In other words, so-called NAT “masquerading” disguises your LAN and makes it seem like a single device is accessing the internet.
Even if everyone in the family is currently connected—let’s say browsing Amazon for woolen socks, playing Minecraft, and scrolling through Instagram. It doesn’t matter! Your router will pretend like all that disparate traffic is originating from a single device.
Okay, but why is that useful?
Actually, NAT “masquerading” was developed for entirely different uses. Still, it works excellently for security: if no hackers can even see that a LAN exists, it’s a lot less appealing for them to try to hack a single device.
Most hackers want to go for nice and meaty LANs. If your router is acting like a single device on the internet, the vast majority of hackers stay clear.
Why Would I Use WAN Blocking?
This is the issue: most routers come set to default block WAN traffic because security is much higher when WAN blocking is disabled.
Unless you’re hoping to operate a WAN or, for example, are operating servers for which external traffic needs access, there’s no reason to enable external WAN connection.
Generally speaking, if you’re reading this article, the advice is simple: ENABLE WAN blocking on your router.
Many router owners (probably everyone who is reading this article now) also enable WAN ping blocking. This is a handy measure that can add extra security.
What is WAN Ping Blocking?
Wait, wait, wait. Back up. What is a WAN Ping?
WAN Ping: What?
A WAN ping is essentially an attempt by external traffic to access a WAP or router. If WAN pinging is enabled, we can think of our router as a bicyclist in the night.
With WAN pinging enabled, the bicyclist has a headlamp on. He or she says, “here I am, world!”
Without WAN pinging enabled, the biker remains stealthy.
What Is Wan Blocking On Router?
Perhaps somewhat contrary to the metaphor, WAN ping blocking is a perfectly safe and even recommended setting for your router.
With WAN ping blocking enabled, it’s difficult for the outside people to locate your LAN; let allow board it and get free internet (or any other kind of mischief).
So, in answer to the question, “what is WAN ping block mode?” Essentially, it’s a way to hide away from hackers. Guests are knocking on the door, but you don’t want to see them. You’re hiding in your room, thinking, “I’m not home. I’m not home.”
How Do You Actually Pronounce WAN?
Unlike our word “wan,” which is pronounced with a vowel sound like the “a” in “father,” WAN is pronounced with an “a” like the vowel in “man.” Likewise with LAN.
Don’t Be Wan, Just Disable WAN
As we have seen in this article, enable WAN connection from external traffic causes, in most cases, more risks than rewards.
If you decide to enable WAN connection from your local home network, any number of hackers or otherwise bad actors can join your LAN and either mooch off you for free internet or devise more devious schemes.
The long and short of it is this: if you want to have maximum security and you’re not running servers from your home, there’s no reason you would need to enable external WAN access.
Enable WAN blocking, enable WAN ping blocking, and allow NAT “masquerading.”
With the three options above enabled (remember, typically the default settings on a new router), your network will be extremely secure.

Блокировка WAN маршрутизатора: безопасно ли включать?
Вот нужно ли вам включать блокировку WAN на вашем маршрутизаторе:
Когда вы включаете переадресацию портов (отключаете блокировку WAN), вы позволяете всему Интернету потенциально перенаправляться на один из внутренних IP-адресов вашей локальной сети.

Если вы не запускаете серверы из своего дома и хотите обеспечить максимальную безопасность, вам не нужно включать внешний доступ к глобальной сети, и вам следует включить блокировку глобальной сети.
Если вы хотите узнать все о том, почему вы должны включить блокировку WAN и что такое блокировка WAN, то вы попали по адресу.
Итак, без лишних слов, давайте сделаем это!
Вам нужно включить блокировку WAN на вашем маршрутизаторе?
Интернет может быть запутанным местом.
Просто быстрый поиск в Google любого термина, связанного с Интернетом, дает сотни тысяч результатов.
Действительно, кажется, что каждый аспект Интернета при ближайшем рассмотрении порождает гораздо больше терминов, которые необходимо изучить, прежде чем полностью понять проблему.
Возможно, вы видели настройку блокировки WAN на новом маршрутизаторе и вам интересно, следует ли вам включать блокировку WAN? Возможно, вы даже не уверены, что это значит.
Краткий ответ таков: да, в большинстве случаев человек, читающий эту статью, должен включить блокировку WAN.
Чтобы узнать, почему вы должны прочитать эту статью.
Ниже вы найдете подробное руководство по глобальной сети:
- Что такое глобальная сеть
- Почему вы должны включить блокировку WAN
- В основном все, что связано
Что такое WAN на вашем маршрутизаторе?
Перво-наперво: нам нужно определить нашу первую переменную.
WAN — это сокращение от Wide Area Network.
Сеть — это, по определению, любое соединение двух или более компьютеров, связанных друг с другом для совместного использования таких утилит, как принтеры, или для совместного использования ресурсов, таких как файлы, и других электронных средств связи.
WAN — это один из двух основных типов сетей, частью которых могут быть компьютеры. Это контрастирует с LAN, что является сокращением от Local Area Network.
В чем разница между WAN и LAN?
WAN — это большая сеть (отсюда и термин «широкая»), которая довольно распространена среди крупных корпораций, университетов и других организаций, которым необходимо соединить множество компьютеров в большом географическом диапазоне.
WAN — это глобальные компьютерные сети. Например, любая сеть, которая пересекает региональные и городские границы на большом расстоянии.
Между тем локальная сеть (как следует из слова «локальный») ограничена меньшим географическим диапазоном. Локальные сети — это компьютерные сети, которые охватывают небольшую географическую область, такую как дом, офис или комплекс зданий.
Подключение по локальной сети
Наиболее типичная локальная сеть находится в доме человека: представьте себе небольшую семью с несколькими компьютерами и только одним принтером.
Соединение этих компьютеров вместе в сеть, чтобы каждый член семьи мог использовать один и тот же принтер, не только покажется очень удобным; подключение к домашнему принтеру, скорее всего, будет основным бытовым требованием для этой семьи.
Когда эта семья подключает свои компьютеры к своему принтеру, они только что сформировали базовую локальную сеть.
Однако локальная сеть может быть больше. Многие региональные офисы с относительно небольшим количеством сотрудников подключены через локальную сеть.
Компьютеры в локальной сети могут быть соединены прямым проводным соединением или беспроводным соединением через WAP (Беспроводные точки доступа). Давайте не будем вдаваться в это здесь, но вы можете Думайте о своем маршрутизаторе как о своем локальном WAP.
WAN-соединение
Если локальная сеть представляет собой соединение нескольких компьютеров для формирования сети, мы можем (в большинстве случаев) думайте о глобальной сети как о соединении локальных сетей в одну большую сеть.
Каковы преимущества подключения к глобальной сети?
Объединение локальных сетей в глобальную сеть имеет ряд очевидных преимуществ для крупных организаций.
Например, представьте, что вы руководитель отдела кадров многонациональной корпорации.
У вас есть ряд учебных модулей, которые вы хотите внедрить единообразно во всей корпорации, чтобы поддерживать определенный стандарт поведения на рабочем месте.
С помощью глобальной сети вы можете хранить эти учебные модули на централизованном узле, к которому легко получить доступ со всех компьютеров в глобальной сети.
При этом каждый сотрудник может одновременно работать в локальной сети своего регионального офиса.
Каковы недостатки подключения к глобальной сети?
Сеть WAN кажется отличной вещью; вы можете подумать про себя.
Что ж, это правда! Это! Но это также менее безопасно.
Предоставление доступа к сети большей группе людей означает, что у хакеров и других бездельников появляется больше точек доступа.
Это не означает, что вы можете полностью списать глобальные сети. Хотите верьте, хотите нет, но вы сейчас находитесь в глобальной сети.
Вот сделка. Интернет на самом деле является крупнейшей глобальной сетью в мире.
Большинство маршрутизаторов имеют один порт WAN для внешнего подключения к Интернету и несколько портов LAN для подключения домашних компьютеров.
Ваш маршрутизатор, в свою очередь, подключится к широкополосному модему, который подключит вас к Интернету.
Вы можете думать об этом так: маршрутизатор направляет весь трафик локальной сети в Интернет. Однако в наши дни большинство интернет-провайдеров (ISP) предоставляют одно устройство, представляющее собой комбинацию маршрутизатора и модема.
Широкополосный модем будет подключен либо через телефонный порт, либо через коаксиальный порт, чтобы ваша локальная сеть имела доступ ко всем великим сокровищам, хранящимся в глобальной сети Интернета.
Включать или не включать WAN?
Итак, теперь мы подошли к сути вопроса. Стоит ли включать блокировку WAN на своем компьютере?
Что ж, давайте сначала разберемся, что такое блокировка WAN на самом деле. является.
Что такое блокировка WAN?
Большинство маршрутизаторов, предоставляемых интернет-провайдерами, по умолчанию настроены на блокировку трафика WAN в вашу локальную сеть. По сути, блокировка WAN предотвращает попадание внешнего интернет-трафика в вашу локальную сеть.
Когда вы открываете переадресацию портов (отключаете блокировку WAN), ВЫ ПОЗВОЛЯЕТЕ ВСЕМ ИНТЕРНЕТУ потенциально перенаправлять себя на один из внутренних IP-адресов вашей локальной сети.
Предоставление Интернету доступа к вашей локальной сети дает им доступ к графическому пользовательскому интерфейсу вашего маршрутизатора или сетевым настройкам, а также к его ICMP: протоколу обнаружения интернет-маршрутизатора.
ICMP — это протокол, по которому ваш компьютер выходит в Интернет через маршрутизатор.
Доступ к ICMP позволит интернет-бродяге использовать ваш маршрутизатор для повторного подключения к Интернету.
Кроме того, многие маршрутизаторы используют NAT (трансляцию сетевых адресов), иначе известную как «маскарад».
Итак, что такое «Маскарад» NAT?
С помощью NAT ваш маршрутизатор подключается к Интернету и ведет себя так, как будто каждый компьютер в вашей локальной сети имеет один и тот же IP-адрес (давайте не будем рассматривать здесь IP-адреса, но вы можете проверить их здесь).
Другими словами, так называемая «маскировка» NAT маскирует вашу локальную сеть и создает впечатление, что одно устройство имеет доступ к Интернету.
Даже если в настоящее время все члены семьи подключены к сети — скажем, просматривают Amazon в поисках шерстяных носков, играют в Minecraft и пролистывают Instagram. Это не имеет значения! Ваш маршрутизатор будет притворяться, что весь разрозненный трафик исходит от одного устройства.
Хорошо, но почему это полезно?
На самом деле «маскировка» NAT была разработана для совсем других целей. Тем не менее, он отлично работает для обеспечения безопасности: если хакеры даже не видят, что локальная сеть существует, для них гораздо менее привлекательно пытаться взломать одно устройство.
Большинство хакеров хотят иметь красивые и мощные локальные сети. Если ваш маршрутизатор работает как единое устройство в Интернете, подавляющее большинство хакеров остаются в стороне.
Зачем мне использовать блокировку WAN?
Вот в чем проблема: большинство маршрутизаторов по умолчанию блокируют трафик WAN, потому что безопасность намного выше когда блокировка WAN отключена.
Если вы не надеетесь использовать глобальную сеть или, например, не используете серверы, для которых требуется доступ к внешнему трафику, нет причин разрешать внешнее подключение к глобальной сети.
Вообще говоря, если вы читаете эту статью, совет прост: ВКЛЮЧИТЕ блокировку WAN на вашем маршрутизаторе.
Многие владельцы роутеров (наверное, все, кто сейчас читает эту статью) также включают блокировку пинга WAN. Это удобная мера, которая может добавить дополнительную безопасность.
Что такое блокировка WAN Ping?
Подожди, подожди, подожди. Резервное копирование. Что такое WAN-пинг?
ВАН Пинг: Что?
Пинг WAN — это, по сути, попытка внешнего трафика получить доступ к WAP или маршрутизатору. Если пинг WAN включен, мы можем думать о нашем маршрутизаторе как о велосипедисте в ночи.
При включенном пинге WAN у велосипедиста горит фара. Он или она говорит: «Вот я, мир!»
Без включенного пинга WAN байкер остается скрытным.
Что такое блокировка WAN на маршрутизаторе?
Возможно, несколько вопреки метафоре, блокировка ping-запросов WAN — это совершенно безопасная и даже рекомендуемая настройка для вашего маршрутизатора.
При включенной блокировке эхо-запросов WAN посторонним людям сложно обнаружить вашу локальную сеть; давайте разрешим садиться и получить бесплатный интернет (или любой другой вид шалости).
Итак, в ответ на вопрос «что такое блочный режим WAN ping?» По сути, это способ спрятаться от хакеров. Гости стучатся в дверь, но ты не хочешь их видеть. Вы прячетесь в своей комнате, думая: «Меня нет дома. Я не дома.»
Как вы на самом деле произносите WAN?
В отличие от нашего слова «wan», которое произносится с гласным звуком, подобным «а» в слове «отец», WAN произносится с «а», как гласный в слове «мужчина». Так же и с локалкой.
Не будь слабым, просто отключи WAN
Как мы видели в этой статье, включение WAN-соединения из-за внешнего трафика в большинстве случаев больше рисков, чем вознаграждений.
Если вы решите включить подключение к глобальной сети из своей локальной домашней сети, любое количество хакеров или других злоумышленников может присоединиться к вашей локальной сети и либо выманить у вас бесплатный доступ в Интернет, либо разработать более изощренные схемы.
Короче говоря, вот что: если вы хотите иметь максимальную безопасность и не запускаете серверы из своего дома, нет причин, по которым вам нужно разрешать доступ к внешней глобальной сети.
Включите блокировку WAN, включите блокировку проверки связи WAN и разрешите «маскировку» NAT.
С включенными тремя указанными выше параметрами (помните, что обычно это настройки по умолчанию на новом маршрутизаторе), ваша сеть будет чрезвычайно безопасной.

Wan Blocking What Is It How To Enable Disable It
WAN blocking prevents specific traffic or network connections from entering or out of a device or network. Through the WAN interface, this can be performed using a router or firewall that can block or filter traffic based on specific criteria such as IP address, port number, or protocol. Furthermore, the primary purpose of WAN blocking is to improve security by preventing unauthorized access or the spread of malicious traffic. Also, it controls internet usage on the web, for example, blocking social media for protection.
Should I disable the WAN port ping for gaming?#
Disabling WAN port ping, also known as ICMP (Internet Control Message Protocol) blocking, can provide additional security for your network, but it may not be necessary specifically for gaming. Disabling WAN port ping can make it more difficult for others to troubleshoot network connectivity issues, such as deciding if a problem is with your system or the network. Also, some online games or services depend on the ICMP to check the network connection status. Therefore, disabling the ICMP may cause connectivity issues with these games or services. It’s your decision whether to disable or enable the WAN port ping, but if you have any doubts, consider consulting an IT professional.
WAN block vs LAN block#
Blocking within LAN refers to restricting access to services within the local area network. So, it’s the same as the WAN block but for local networks. ISPs usually employ LAN blocking to restrict access to certain services for the users. Also, you can read on Xbox error ICMP fix to enjoy your games.

Wan blocking что это
From what I understand WAN blocking disables the use of the WI-FI Access Point (WI-FI AP) and restricts Internet use to LAN/hardwired connections. … If what you want is to block certain computers OR allow only specific computers to connect to your Internet; what you want is called MAC Filtering.
Do I need WAN for WIFI?, In short, LAN ports on a router allow Ethernet-ready devices to connect to one another and share data. In order for them to also access the internet, the router needs to have a Wide Area Network (WAN) port.
Furthermore, What is WAN Ping Blocking?, WAN Ping Blocking feature prevents Internet Control Message Protocol (ICMP) pings to the Wide Area Network (WAN) interface of the WTM652G/NA. This is ideal for preventing unwanted attacks from the Internet when the gateway is left online for extended period of time.
Finally, What is a wan on a router?, A Wide Area Network (WAN) is a network that exists over a large-scale geographical area. Your modem sends and receives information to and from the internet through its WAN port.

No, you should not. The only time you would need it enabled would be if if you are having network problems and want to troubleshoot your Router or Modem. Leaving the ping response enabled is just sending an invitation to hackers. … Check your WAN (Internet) port IP address on the router.
What is a wan on a router?
A Wide Area Network (WAN) is a network that exists over a large-scale geographical area. Your modem sends and receives information to and from the internet through its WAN port.
Can I use the WAN port on my router?
Wide-area network (WAN) port: Also known as the internet port. Generally, a router has just one WAN port. … A WAN port is used to connect to an internet source, such as a broadband modem. The WAN allows the router to connect to the internet and share that connection with all the Ethernet-ready devices connected to it.
Should I enable WAN on my router?
This is whether you need to enable WAN blocking on your router. The short answer: Yes.
Should I use WAN or LAN port?
Use the LAN ports on your wireless router to connect devices on your home network, such as computers or printers. Connect the WAN port to your modem or another device hooked up to the public internet.
What is difference between WAN and LAN on router?
WAN stands for Wide Area Network and this is the network that connects your router to your service provider. The WAN port usually connects to a DSL modem, cable modem or fibre media converter. LAN stands for Local Area Network and this is the network that connects the devices within your home/business to the router.
Should I block WAN Ping on my router?
No, you should not. The only time you would need it enabled would be if if you are having network problems and want to troubleshoot your Router or Modem. Leaving the ping response enabled is just sending an invitation to hackers.
Should I enable WAN Ping?
There is no benefit to allowing ping on the WAN. Basically a ping means that the router and the IP addressed assigned to your modem will respond back to a “ping” from outside your home network.
Do I need WAN for WIFI?
In short, LAN ports on a router allow Ethernet-ready devices to connect to one another and share data. In order for them to also access the internet, the router needs to have a Wide Area Network (WAN) port.
Can ping be blocked?
Ping uses Internet Control Message Protocol, this also is used for other errors and stuff like preventing a packet ending up in an infinite loop around a group of routers. By blocking ICMP Echo Request packets or just not responding to them you can block a ping without blocking all other control codes.
Should I enable WAN on my router?
This is whether you need to enable WAN blocking on your router. The short answer: Yes.
What is the difference between WAN and WiFi?
The WAN port in a WiFi router is essentially connecting you to the real “internet”. The cable coming out of modem, or if a PPPoE connection, a simple RJ45 ethernet cable are to be plugged in the WAN port. And then, you can access internet.
What does Wan mean on my router?
A Wide Area Network (WAN) is a network that exists over a large-scale geographical area. Your modem sends and receives information to and from the internet through its WAN port.
Should I use WAN or LAN port?

What Is WAN on Your Router?
First things first: we need to define our first variable.
WAN is short for Wide Area Network.
A network is by definition any connection of two or more computers linked together to share utilities such as printers or to share resources such as files and otherwise communicate electronically.
A WAN is one of two basic kinds of networks that computers can be a part of. It contrasts with LAN, which is short for Local Area Network.
What Is the Difference Between WAN and LAN?
A WAN is a large network (hence the term “wide”) that is quite common amongst large corporate entities, universities, and other organizations that need to connect many computers over a large geographic range.
WANs are broad-area computer networks. For instance, any network that crosses regional and metropolitan boundaries over a great distance.
A LAN, meanwhile, is (as the word “local” implies) limited to a smaller geographic range. LANs are computer networks that cover a small geographic area, such as a house, office, or building complex.
LAN Connection
The most typical LAN is found in an individual’s home: imagine a small family with multiple computers and only one printer.
Connecting these computers together in a network so that each member of the family can use the same printer will not only seem very handy; connecting to the home printer will likely be a basic household requirement for this family.
When this family connects their computers to their printer, they have just formed a basic LAN.
A LAN can be larger, however. Many regional offices with a relatively small number of employees are connected via LAN.
Computers on a LAN can be connected by being wired directly together, or they can be connected wirelessly via WAPs (Wireless Access Points). Let’s don’t go into that here, but you can think of your router as your local WAP.
WAN Connection
If a LAN is a connection of multiple computers to form a network, we can (in most cases) think of a WAN as a connection of LANs together in one large network.
What Are the Advantages of a WAN Network Connection?
Connecting LANs together to form a WAN network has a variety of obvious advantages for large organizations.
For example, imagine you are the head of HR for a multinational corporation.
You have a series of training modules that you want to be implemented uniformly across the corporation to maintain a certain standard in workplace comportment.
With a WAN, you can store these training modules on a centralized node that is easily accessible by all computers on the WAN.
Each employee, meanwhile, may simultaneously be operating on their regional office’s LAN.
What Are the Disadvantages of a WAN Network Connection?
A WAN network sounds like a great thing; you might be thinking to yourself.
Well, that’s the truth! It is! But it’s also less secure.
Allowing a larger group of people to access the network means there are more access points for hackers and other ne’er-do-wells.
Now, that’s not to say that you can write off WANs completely. Believe it or not, you’re on a WAN right now.
How Is WAN Related to the Internet?
Here’s the deal. The internet is actually the largest WAN network in the world.
Most routers have a single WAN port to allow for the exterior internet connection and multiple LAN ports to hook up home computers.
Your router will, in turn, connect to a broadband modem that will connect you to the internet.
You can think of it this way: the router routes all LAN traffic to the internet. Most internet service providers (ISP) these days will, however, provide a single device that is a router-modem combo.
The broadband modem will be connected by either a telephone port or coaxial port to allow your LAN to access all of the great treasures stored on the WAN of the internet.
To Enable or Not to Enable WAN?
So, now we come to the crux of the issue. Should you enable WAN blocking on your computer?
Well, let’s first take a look at what WAN blocking actually is.
What is WAN Blocking?
Most routers provided by ISPs will come default set to block WAN traffic to your LAN. In essence, WAN blocking keeps external internet traffic from entering your LAN.
When you open up port forwarding (disable WAN blocking), YOU ALLOW THE ENTIRE INTERNET to potentially redirect itself to one of the internal IP addresses of your LAN.
Allowing the internet to access your local area network gives them access to your router’s GUI (Graphic User Interface) or online settings, as well as its ICMP: Internet Router Discovery Protocol.
The ICMP is the protocol whereby your computer accesses the internet via the router.
Access to the ICMP would allow an internet vagrant to use your router to reconnect themselves to the internet.
In addition, many routers use NAT (Network Address Translation), otherwise known as “masquerading.”
So, What is NAT “Masquerading?”
With NAT, your router connects to the internet and acts like every computer on your LAN is the exact same IP address (let’s not cover IP addresses here, but you can check those out here).
In other words, so-called NAT “masquerading” disguises your LAN and makes it seem like a single device is accessing the internet.
Even if everyone in the family is currently connected—let’s say browsing Amazon for woolen socks, playing Minecraft, and scrolling through Instagram. It doesn’t matter! Your router will pretend like all that disparate traffic is originating from a single device.
Okay, but why is that useful?
Actually, NAT “masquerading” was developed for entirely different uses. Still, it works excellently for security: if no hackers can even see that a LAN exists, it’s a lot less appealing for them to try to hack a single device.
Most hackers want to go for nice and meaty LANs. If your router is acting like a single device on the internet, the vast majority of hackers stay clear.
Why Would I Use WAN Blocking?
This is the issue: most routers come set to default block WAN traffic because security is much higher when WAN blocking is disabled.
Unless you’re hoping to operate a WAN or, for example, are operating servers for which external traffic needs access, there’s no reason to enable external WAN connection.
Generally speaking, if you’re reading this article, the advice is simple: ENABLE WAN blocking on your router.
Many router owners (probably everyone who is reading this article now) also enable WAN ping blocking. This is a handy measure that can add extra security.
What is WAN Ping Blocking?
Wait, wait, wait. Back up. What is a WAN Ping?
WAN Ping: What?
A WAN ping is essentially an attempt by external traffic to access a WAP or router. If WAN pinging is enabled, we can think of our router as a bicyclist in the night.
With WAN pinging enabled, the bicyclist has a headlamp on. He or she says, “here I am, world!”
Without WAN pinging enabled, the biker remains stealthy.
What Is Wan Blocking On Router?
Perhaps somewhat contrary to the metaphor, WAN ping blocking is a perfectly safe and even recommended setting for your router.
With WAN ping blocking enabled, it’s difficult for the outside people to locate your LAN; let allow board it and get free internet (or any other kind of mischief).
So, in answer to the question, “what is WAN ping block mode?” Essentially, it’s a way to hide away from hackers. Guests are knocking on the door, but you don’t want to see them. You’re hiding in your room, thinking, “I’m not home. I’m not home.”
How Do You Actually Pronounce WAN?
Unlike our word “wan,” which is pronounced with a vowel sound like the “a” in “father,” WAN is pronounced with an “a” like the vowel in “man.” Likewise with LAN.
Don’t Be Wan, Just Disable WAN
As we have seen in this article, enable WAN connection from external traffic causes, in most cases, more risks than rewards.
If you decide to enable WAN connection from your local home network, any number of hackers or otherwise bad actors can join your LAN and either mooch off you for free internet or devise more devious schemes.
The long and short of it is this: if you want to have maximum security and you’re not running servers from your home, there’s no reason you would need to enable external WAN access.
Enable WAN blocking, enable WAN ping blocking, and allow NAT “masquerading.”
With the three options above enabled (remember, typically the default settings on a new router), your network will be extremely secure.
WAN Blocking: What Is It & How to Enable/Disable It
Have you seen WAN blocking on your router? Do you need an idea of WAN blocking and how to enable or disable it? Well, you have come across a helpful guide cause this guide will tell you all you need to know about WAN blocking.
What does WAN blocking mean?
WAN blocking prevents specific traffic or network connections from entering or out of a device or network. Through the WAN interface, this can be performed using a router or firewall that can block or filter traffic based on specific criteria such as IP address, port number, or protocol.
Furthermore, the primary purpose of WAN blocking is to improve security by preventing unauthorized access or the spread of malicious traffic. Also, it controls internet usage on the web, for example, blocking social media for protection.
Should I disable the WAN port ping for gaming?
Disabling WAN port ping, also known as ICMP (Internet Control Message Protocol) blocking, can provide additional security for your network, but it may not be necessary specifically for gaming.
Disabling WAN port ping can make it more difficult for others to troubleshoot network connectivity issues, such as deciding if a problem is with your system or the network.
Also, some online games or services depend on the ICMP to check the network connection status. Therefore, disabling the ICMP may cause connectivity issues with these games or services.
It’s your decision whether to disable or enable the WAN port ping, but if you have any doubts, consider consulting an IT professional.
WAN block vs LAN block
Blocking within LAN refers to restricting access to services within the local area network. So, it’s the same as the WAN block but for local networks.
ISPs usually employ LAN blocking to restrict access to certain services for the users.

What is WAN Blocking?
In today’s connected world, businesses rely heavily on wide area networks (WANs) to enable communication and collaboration across multiple locations. However, the open nature of WANs can also leave them vulnerable to security breaches and unauthorized access. This is where WAN blocking comes into play.
To maximize the benefits of WAN blocking, businesses should follow best practices such as proper configuration and implementation, regular maintenance and monitoring, and effective communication with end-users. By doing so, businesses can ensure that their networks remain secure and optimized for performance while also providing a positive user experience.
Overall, WAN blocking plays a critical role in protecting modern networks from various security threats. As businesses continue to rely on WANs for their day-to-day operations, it is vital to implement effective WAN-blocking strategies to mitigate risks and ensure business continuity.
What is WAN Blocking?
WAN blocking refers to selectively blocking certain types of network traffic, whether specific ports, IP addresses, or domains. The main purpose of WAN blocking is to enhance network security and prevent unauthorized access, which can potentially compromise sensitive data and resources.
In addition to security benefits, WAN blocking also provides privacy and network performance advantages. By restricting access to certain websites or applications, businesses can ensure that employees are only accessing authorized resources and prevent data leaks. Moreover, WAN blocking can also improve network performance by reducing congestion and prioritizing critical applications.
However, WAN blocking has some drawbacks, including limited access to specific websites and reduced user convenience. Finding and resolving issues related to WAN blocking can also be challenging, requiring expert knowledge and resources.
Types of WAN Blocking
Businesses can implement several types of WAN blocking techniques to enhance network security and control. Here are the most common ones:
In summary, implementing different types of WAN blocking techniques can help businesses reduce the risk of security breaches and ensure compliance with regulatory requirements. However, it’s essential to implement these techniques properly and regularly review and update them to ensure they remain effective against emerging threats.
Port Blocking
Port blocking involves closing specific ports on a network to prevent unauthorized access to certain applications or services. Different types of traffic use different ports, and attackers more commonly target some than others. By blocking unnecessary ports, businesses can reduce the risk of security breaches and minimize the attack surface of their network.
For example, businesses can block access to port 25, commonly used for sending emails, to prevent spam and malware attacks. Similarly, blocking ports commonly used by peer-to-peer file-sharing applications or gaming platforms can prevent excessive bandwidth consumption and reduce the risk of network congestion.
IP Blocking
IP blocking is a technique used to restrict access to network resources based on the source or destination IP address. This can be useful for preventing unauthorized access to critical resources or blocking traffic from known malicious IP addresses.
For example, businesses can use IP blocking to block traffic from countries or regions where they don’t do business or to restrict access to resources for certain groups of users. IP blocking can also block traffic from known malicious IP addresses or restrict access to certain resources based on IP addresses.
DNS Blocking
DNS blocking involves blocking traffic based on domain names or URLs. This technique can prevent access to known malicious or inappropriate websites or restrict access to certain websites for compliance reasons.
For example, businesses can use DNS blocking to prevent employees from accessing websites that violate company policies, such as social media or gambling sites. DNS blocking can also prevent access to known phishing or malware distribution sites.
Benefits of WAN Blocking
WAN blocking can provide several benefits for businesses, including enhanced security, improved privacy, and better network performance. Here are the key benefits of implementing WAN blocking:
- Enhanced Security: The primary benefit of WAN blocking is enhanced security. By selectively blocking certain types of network traffic, businesses can prevent unauthorized access and mitigate various security risks, including malware attacks, data breaches, and phishing scams.
WAN blocking can also help businesses comply with regulatory requirements related to data privacy and security. By restricting access to certain websites or applications, businesses can ensure that employees are only accessing authorized resources and prevent data leaks.
- Improved Privacy: WAN blocking can also enhance privacy by blocking access to websites or applications that collect and use personal data without consent. By implementing DNS blocking or IP blocking, businesses can prevent employees from accessing websites or applications that are known to violate privacy laws or company policies.
- Better Network Performance: WAN blocking can also improve network performance by reducing congestion and prioritizing critical applications. By blocking non-essential traffic or limiting bandwidth for certain applications, businesses can ensure that their networks remain optimized for critical operations and minimize the risk of slowdowns or outages.
Implementing WAN blocking can provide businesses with various security, privacy, and performance benefits.
However, it’s crucial to balance these benefits against potential drawbacks, such as limitations on user convenience and the need for expert knowledge and resources to implement and maintain effective WAN blocking strategies.
Drawbacks of WAN Blocking
While WAN blocking can provide several benefits for businesses, some potential drawbacks should be considered before implementing these techniques. Here are some of the key drawbacks of WAN blocking:
- Limitations on User Convenience: One of the main drawbacks of WAN blocking is that it can limit user convenience by restricting access to certain websites, applications, or services. While this can enhance security and privacy, it can also lead to frustration and reduced productivity among employees who need access to these resources to perform their jobs effectively.
To mitigate this issue, businesses can implement exceptions or workarounds for specific users or departments that require access to blocked resources. However, this can increase the complexity and cost of implementing and maintaining WAN blocking strategies.
- Need for Expert Knowledge and Resources: Implementing effective WAN blocking strategies requires specialized knowledge and resources, including expertise in network security, traffic analysis, and regulatory compliance. Small businesses or those without dedicated IT staff may struggle to implement and maintain these techniques effectively, which can lead to security breaches or performance issues.
To overcome this challenge, businesses can consider outsourcing WAN blocking to third-party providers who have the necessary expertise and resources. However, this can increase the cost and complexity of WAN blocking implementation and management.
- Potential for False Positives: WAN blocking techniques, such as IP or DNS blocking, can sometimes result in false positives, which means legitimate traffic is mistakenly blocked. This can occur when IP addresses or domain names are incorrectly identified as malicious or inappropriate, leading to access restrictions that can impact business operations.
To reduce the risk of false positives, businesses can implement comprehensive testing and monitoring procedures to identify and resolve issues quickly. However, this can increase the complexity and cost of WAN blocking implementation and management.
While WAN blocking can provide several benefits for businesses related to security, privacy, and performance, there are also potential drawbacks that should be considered.
By carefully weighing these factors and implementing WAN blocking strategies, businesses can ensure they achieve the desired results while minimizing risks and limitations.
Best Practices for WAN Blocking
Implementing effective WAN blocking strategies requires careful planning, expert knowledge, and ongoing monitoring and management.
Here are some best practices for WAN blocking that businesses should consider:
- Develop a Comprehensive Strategy: Before implementing WAN blocking techniques, businesses should develop a comprehensive strategy that aligns with their overall security, privacy, and performance goals. This strategy should consider factors such as which types of traffic to block, which resources to prioritize, and how to manage exceptions and false positives.
- Prioritize User Education and Awareness: To mitigate the impact of WAN blocking on user convenience and productivity, businesses should prioritize user education and awareness. This includes providing clear guidelines and policies related to access blocked resources and training and support for employees who need to use workarounds or exceptions.
- Implement Comprehensive Monitoring and Testing: To ensure that WAN blocking strategies are effective and do not result in false positives or other issues, businesses should implement comprehensive monitoring and testing procedures. This includes regularly reviewing logs and reports related to WAN blocking and conducting regular penetration testing and vulnerability assessments.
- Partner with Expert Providers: Implementing effective WAN blocking strategies can be challenging, particularly for small businesses or those without dedicated IT staff. To overcome this challenge, businesses can consider partnering with expert providers who offer WAN blocking solutions and services. These providers can offer specialized knowledge and resources to help businesses effectively implement and manage WAN blocking.
- Continuously Evaluate and Improve: WAN blocking strategies should be continuously evaluated and improved to ensure they remain effective and aligned with business goals. This includes regularly reviewing and updating policies and procedures and implementing new technologies and techniques as needed.
By following these best practices for WAN blocking, businesses can enhance their security, privacy, and performance while minimizing risks and limitations.
However, it’s crucial to balance the benefits of WAN blocking against potential drawbacks and to implement these strategies carefully and thoughtfully.

- В основном все, что связано
Что такое WAN на вашем маршрутизаторе?
Перво-наперво: нам нужно определить нашу первую переменную.
WAN — это сокращение от Wide Area Network.
Сеть — это, по определению, любое соединение двух или более компьютеров, связанных друг с другом для совместного использования таких утилит, как принтеры, или для совместного использования ресурсов, таких как файлы, и других электронных средств связи.
WAN — это один из двух основных типов сетей, частью которых могут быть компьютеры. Это контрастирует с LAN, что является сокращением от Local Area Network.
В чем разница между WAN и LAN?
WAN — это большая сеть (отсюда и термин «широкая»), которая довольно распространена среди крупных корпораций, университетов и других организаций, которым необходимо соединить множество компьютеров в большом географическом диапазоне.
WAN — это глобальные компьютерные сети. Например, любая сеть, которая пересекает региональные и городские границы на большом расстоянии.
Между тем локальная сеть (как следует из слова «локальный») ограничена меньшим географическим диапазоном. Локальные сети — это компьютерные сети, которые охватывают небольшую географическую область, такую как дом, офис или комплекс зданий.
Подключение по локальной сети
Наиболее типичная локальная сеть находится в доме человека: представьте себе небольшую семью с несколькими компьютерами и только одним принтером.
Соединение этих компьютеров вместе в сеть, чтобы каждый член семьи мог использовать один и тот же принтер, не только покажется очень удобным; подключение к домашнему принтеру, скорее всего, будет основным бытовым требованием для этой семьи.
Когда эта семья подключает свои компьютеры к своему принтеру, они только что сформировали базовую локальную сеть.
Однако локальная сеть может быть больше. Многие региональные офисы с относительно небольшим количеством сотрудников подключены через локальную сеть.
Компьютеры в локальной сети могут быть соединены прямым проводным соединением или беспроводным соединением через WAP (Беспроводные точки доступа). Давайте не будем вдаваться в это здесь, но вы можете Думайте о своем маршрутизаторе как о своем локальном WAP.
WAN-соединение
Если локальная сеть представляет собой соединение нескольких компьютеров для формирования сети, мы можем (в большинстве случаев) думайте о глобальной сети как о соединении локальных сетей в одну большую сеть.
Каковы преимущества подключения к глобальной сети?
Объединение локальных сетей в глобальную сеть имеет ряд очевидных преимуществ для крупных организаций.
Например, представьте, что вы руководитель отдела кадров многонациональной корпорации.
У вас есть ряд учебных модулей, которые вы хотите внедрить единообразно во всей корпорации, чтобы поддерживать определенный стандарт поведения на рабочем месте.
С помощью глобальной сети вы можете хранить эти учебные модули на централизованном узле, к которому легко получить доступ со всех компьютеров в глобальной сети.
При этом каждый сотрудник может одновременно работать в локальной сети своего регионального офиса.
Каковы недостатки подключения к глобальной сети?
Сеть WAN кажется отличной вещью; вы можете подумать про себя.
Что ж, это правда! Это! Но это также менее безопасно.
Предоставление доступа к сети большей группе людей означает, что у хакеров и других бездельников появляется больше точек доступа.
Это не означает, что вы можете полностью списать глобальные сети. Хотите верьте, хотите нет, но вы сейчас находитесь в глобальной сети.
Вот сделка. Интернет на самом деле является крупнейшей глобальной сетью в мире.
Большинство маршрутизаторов имеют один порт WAN для внешнего подключения к Интернету и несколько портов LAN для подключения домашних компьютеров.
Ваш маршрутизатор, в свою очередь, подключится к широкополосному модему, который подключит вас к Интернету.
Вы можете думать об этом так: маршрутизатор направляет весь трафик локальной сети в Интернет. Однако в наши дни большинство интернет-провайдеров (ISP) предоставляют одно устройство, представляющее собой комбинацию маршрутизатора и модема.
Широкополосный модем будет подключен либо через телефонный порт, либо через коаксиальный порт, чтобы ваша локальная сеть имела доступ ко всем великим сокровищам, хранящимся в глобальной сети Интернета.
Включать или не включать WAN?
Итак, теперь мы подошли к сути вопроса. Стоит ли включать блокировку WAN на своем компьютере?
Что ж, давайте сначала разберемся, что такое блокировка WAN на самом деле. является.
Что такое блокировка WAN?
Большинство маршрутизаторов, предоставляемых интернет-провайдерами, по умолчанию настроены на блокировку трафика WAN в вашу локальную сеть. По сути, блокировка WAN предотвращает попадание внешнего интернет-трафика в вашу локальную сеть.
Когда вы открываете переадресацию портов (отключаете блокировку WAN), ВЫ ПОЗВОЛЯЕТЕ ВСЕМ ИНТЕРНЕТУ потенциально перенаправлять себя на один из внутренних IP-адресов вашей локальной сети.
Предоставление Интернету доступа к вашей локальной сети дает им доступ к графическому пользовательскому интерфейсу вашего маршрутизатора или сетевым настройкам, а также к его ICMP: протоколу обнаружения интернет-маршрутизатора.
ICMP — это протокол, по которому ваш компьютер выходит в Интернет через маршрутизатор.
Доступ к ICMP позволит интернет-бродяге использовать ваш маршрутизатор для повторного подключения к Интернету.
Кроме того, многие маршрутизаторы используют NAT (трансляцию сетевых адресов), иначе известную как «маскарад».
Итак, что такое «Маскарад» NAT?
С помощью NAT ваш маршрутизатор подключается к Интернету и ведет себя так, как будто каждый компьютер в вашей локальной сети имеет один и тот же IP-адрес (давайте не будем рассматривать здесь IP-адреса, но вы можете проверить их здесь).
Другими словами, так называемая «маскировка» NAT маскирует вашу локальную сеть и создает впечатление, что одно устройство имеет доступ к Интернету.
Даже если в настоящее время все члены семьи подключены к сети — скажем, просматривают Amazon в поисках шерстяных носков, играют в Minecraft и пролистывают Instagram. Это не имеет значения! Ваш маршрутизатор будет притворяться, что весь разрозненный трафик исходит от одного устройства.
Хорошо, но почему это полезно?
На самом деле «маскировка» NAT была разработана для совсем других целей. Тем не менее, он отлично работает для обеспечения безопасности: если хакеры даже не видят, что локальная сеть существует, для них гораздо менее привлекательно пытаться взломать одно устройство.
Большинство хакеров хотят иметь красивые и мощные локальные сети. Если ваш маршрутизатор работает как единое устройство в Интернете, подавляющее большинство хакеров остаются в стороне.
Зачем мне использовать блокировку WAN?
Вот в чем проблема: большинство маршрутизаторов по умолчанию блокируют трафик WAN, потому что безопасность намного выше когда блокировка WAN отключена.
Если вы не надеетесь использовать глобальную сеть или, например, не используете серверы, для которых требуется доступ к внешнему трафику, нет причин разрешать внешнее подключение к глобальной сети.
Вообще говоря, если вы читаете эту статью, совет прост: ВКЛЮЧИТЕ блокировку WAN на вашем маршрутизаторе.
Многие владельцы роутеров (наверное, все, кто сейчас читает эту статью) также включают блокировку пинга WAN. Это удобная мера, которая может добавить дополнительную безопасность.
Что такое блокировка WAN Ping?
Подожди, подожди, подожди. Резервное копирование. Что такое WAN-пинг?
ВАН Пинг: Что?
Пинг WAN — это, по сути, попытка внешнего трафика получить доступ к WAP или маршрутизатору. Если пинг WAN включен, мы можем думать о нашем маршрутизаторе как о велосипедисте в ночи.
При включенном пинге WAN у велосипедиста горит фара. Он или она говорит: «Вот я, мир!»
Без включенного пинга WAN байкер остается скрытным.
Что такое блокировка WAN на маршрутизаторе?
Возможно, несколько вопреки метафоре, блокировка ping-запросов WAN — это совершенно безопасная и даже рекомендуемая настройка для вашего маршрутизатора.
При включенной блокировке эхо-запросов WAN посторонним людям сложно обнаружить вашу локальную сеть; давайте разрешим садиться и получить бесплатный интернет (или любой другой вид шалости).
Итак, в ответ на вопрос «что такое блочный режим WAN ping?» По сути, это способ спрятаться от хакеров. Гости стучатся в дверь, но ты не хочешь их видеть. Вы прячетесь в своей комнате, думая: «Меня нет дома. Я не дома.»
Как вы на самом деле произносите WAN?
В отличие от нашего слова «wan», которое произносится с гласным звуком, подобным «а» в слове «отец», WAN произносится с «а», как гласный в слове «мужчина». Так же и с локалкой.
Не будь слабым, просто отключи WAN
Как мы видели в этой статье, включение WAN-соединения из-за внешнего трафика в большинстве случаев больше рисков, чем вознаграждений.
Если вы решите включить подключение к глобальной сети из своей локальной домашней сети, любое количество хакеров или других злоумышленников может присоединиться к вашей локальной сети и либо выманить у вас бесплатный доступ в Интернет, либо разработать более изощренные схемы.
Короче говоря, вот что: если вы хотите иметь максимальную безопасность и не запускаете серверы из своего дома, нет причин, по которым вам нужно разрешать доступ к внешней глобальной сети.
Включите блокировку WAN, включите блокировку проверки связи WAN и разрешите «маскировку» NAT.
С включенными тремя указанными выше параметрами (помните, что обычно это настройки по умолчанию на новом маршрутизаторе), ваша сеть будет чрезвычайно безопасной.

What is WAN blocking?
It’s a process that prevents the transmission of data over Internet Protocol (IP) networks. It occurs when there are too many packets to be transmitted at once, and it can lead to significant delays in network performance.
WAN blockers work by slowing down traffic on one or more computers within the network, which forces all other traffic to slow down as well. These devices usually operate on layer 2 of the OSI model, which means they filter out unwanted transmissions before they reach layer 3 (the networking part). This way, only those packets with a destination address matching the blockers will be allowed through. The net result is that less bandwidth is available for use by anyone else who might need it.

What is WAN blocking?
WAN blocking is a type of internet censorship that is employed by the government or an ISP to block certain content. The term “WAN” stands for Wide Area Network and this type of censorship is used to prevent access to websites and other content from outside sources. Typically, these blocks are imposed on Internet Service Providers and other service providers and they work by inspecting the packets and looking at the address information in them.
WAN blocking can be done either through domain name system (DNS) filtering or packet filtering techniques. With DNS filtering, the ISP looks up all packets that are coming in for IP addresses and filters them by their domain name. Packet filtering is when packets are looked at to see what protocol they carry, where they come from, and where they are going. If the traffic matches certain criteria set up by the internet service provider or government agency, then the packets are dropped or blocked completely.
How many types of WAN blocking are there?
There are 3 different types of WAN blocking: IP blocking, MAC address filtering, and IP Address Filtering.
IP blocking is a form of WAN blocking that targets a specific device by looking at its IP address. In order to block a device, the system administrator must determine that device’s IP address and then add it to a list. During this process, the administrator will also select how long that device is to be blocked. This could be anywhere from 1 minute up to several hours or even indefinitely.
MAC address filtering is another form of WAN blocking that allows a system administrator to block a device by looking at its MAC address. In order to do this, the administrator must first input the MAC addresses of all devices allowed on the network as well as those which are not allowed. The blocking will take place based on whichever category the device falls into. If the device is not in that category, it will be allowed access to the network.
The last form of WAN blocking is IP address filtering, which can block an IP address from accessing a network by looking at its IP address. During this process, the administrator must also input how long it should be blocked for or whether or not a specific time should be used instead. If it is to be blocked indefinitely, the administrator will have to manually unblock it for as long as they desire.
Why would any company need to use it?
A company might want to use this technology for security reasons. For example, if people are using the wifi for the internet, there may be malware on the network that could harm an organization’s system.
If a user is in a sensitive area of the network, they might not want other users on the same wifi to see what they are doing. It’s also important to note that many companies don’t allow access from outside the internet during business hours. If it turns out a user isn’t using the company wifi when they should be, it helps them enforce that rule.
An organization may not want sensitive documents being sent out or received during business hours. If there are employees that need to have access outside of normal working hours, blocking WAN traffic can help allow them to do so while still maintaining security for the rest of the organization.
When should I use it?
There are two times in which you would use a WAN block:
1) For protection against hackers- when networks are linked to the Internet, they are vulnerable to attacks by hackers. As the networks are much more vulnerable, WAN blocking is used to provide protection.
2) To throttle bandwidth for an individual- LAN users may also be able to benefit from the use of this function. This is because it can help control usage when there are many people in one location or office.
Conclusion
WAN blocking is a technique that prevents people from accessing websites, applications, and other content on your network. WAN blocking can be useful for companies who want to block specific sites or apps during certain hours of the day or week. In some cases, an organization might need to do this in order to comply with laws such as COPPA (Children’s Online Privacy Protection Act) which requires parental consent before collecting personal data from children under 13 years old. Some organizations believe they may have legitimate reasons for needing to prohibit access outside their physical location using WAN blocking techniques so employees are more productive at work. WAN blocking is not the same as WAN optimization, but it can be combined with WAN optimization.
Wan Blocking What Is It How To Enable Disable It
WAN blocking prevents specific traffic or network connections from entering or out of a device or network. Through the WAN interface, this can be performed using a router or firewall that can block or filter traffic based on specific criteria such as IP address, port number, or protocol. Furthermore, the primary purpose of WAN blocking is to improve security by preventing unauthorized access or the spread of malicious traffic. Also, it controls internet usage on the web, for example, blocking social media for protection.
Should I disable the WAN port ping for gaming?#
Disabling WAN port ping, also known as ICMP (Internet Control Message Protocol) blocking, can provide additional security for your network, but it may not be necessary specifically for gaming. Disabling WAN port ping can make it more difficult for others to troubleshoot network connectivity issues, such as deciding if a problem is with your system or the network. Also, some online games or services depend on the ICMP to check the network connection status. Therefore, disabling the ICMP may cause connectivity issues with these games or services. It’s your decision whether to disable or enable the WAN port ping, but if you have any doubts, consider consulting an IT professional.
WAN block vs LAN block#
Blocking within LAN refers to restricting access to services within the local area network. So, it’s the same as the WAN block but for local networks. ISPs usually employ LAN blocking to restrict access to certain services for the users. Also, you can read on Xbox error ICMP fix to enjoy your games.

If you want to learn all about why you should enable WAN blocking and what WAN blocking is, then you’re in the right place.
So without further ado, let’s do this!
Do You Need to Enable WAN Blocking on Your Router?
The internet can be a confusing place.
Just a quick google search of any term related to the internet yields hundreds of thousands of results.
Indeed, each aspect of the internet seems to, upon closer inspection, give birth to many more terms that one must learn before one fully understands the issue.
Perhaps you’ve seen the WAN blocking setting on a new router and are curious about whether or not you should enable WAN blocking? Perhaps you’re not even sure what this means.
The short answer is this: yes, in most cases, the person reading this article should enable WAN blocking.
To find out why you should read this article.
Below you’ll find your comprehensive WAN guide:

- Why you should enable WAN blocking
- Basically everything related
What Is WAN on Your Router?
First things first: we need to define our first variable.
WAN is short for Wide Area Network.
A network is by definition any connection of two or more computers linked together to share utilities such as printers or to share resources such as files and otherwise communicate electronically.
A WAN is one of two basic kinds of networks that computers can be a part of. It contrasts with LAN, which is short for Local Area Network.
What Is the Difference Between WAN and LAN?
A WAN is a large network (hence the term “wide”) that is quite common amongst large corporate entities, universities, and other organizations that need to connect many computers over a large geographic range.
WANs are broad-area computer networks. For instance, any network that crosses regional and metropolitan boundaries over a great distance.
A LAN, meanwhile, is (as the word “local” implies) limited to a smaller geographic range. LANs are computer networks that cover a small geographic area, such as a house, office, or building complex.
LAN Connection
The most typical LAN is found in an individual’s home: imagine a small family with multiple computers and only one printer.
Connecting these computers together in a network so that each member of the family can use the same printer will not only seem very handy; connecting to the home printer will likely be a basic household requirement for this family.
When this family connects their computers to their printer, they have just formed a basic LAN.
A LAN can be larger, however. Many regional offices with a relatively small number of employees are connected via LAN.
Computers on a LAN can be connected by being wired directly together, or they can be connected wirelessly via WAPs (Wireless Access Points). Let’s don’t go into that here, but you can think of your router as your local WAP.
WAN Connection
If a LAN is a connection of multiple computers to form a network, we can (in most cases) think of a WAN as a connection of LANs together in one large network.
What Are the Advantages of a WAN Network Connection?
Connecting LANs together to form a WAN network has a variety of obvious advantages for large organizations.
For example, imagine you are the head of HR for a multinational corporation.
You have a series of training modules that you want to be implemented uniformly across the corporation to maintain a certain standard in workplace comportment.
With a WAN, you can store these training modules on a centralized node that is easily accessible by all computers on the WAN.
Each employee, meanwhile, may simultaneously be operating on their regional office’s LAN.
What Are the Disadvantages of a WAN Network Connection?
A WAN network sounds like a great thing; you might be thinking to yourself.
Well, that’s the truth! It is! But it’s also less secure.
Allowing a larger group of people to access the network means there are more access points for hackers and other ne’er-do-wells.
Now, that’s not to say that you can write off WANs completely. Believe it or not, you’re on a WAN right now.
How Is WAN Related to the Internet?
Here’s the deal. The internet is actually the largest WAN network in the world.
Most routers have a single WAN port to allow for the exterior internet connection and multiple LAN ports to hook up home computers.
Your router will, in turn, connect to a broadband modem that will connect you to the internet.
You can think of it this way: the router routes all LAN traffic to the internet. Most internet service providers (ISP) these days will, however, provide a single device that is a router-modem combo.
The broadband modem will be connected by either a telephone port or coaxial port to allow your LAN to access all of the great treasures stored on the WAN of the internet.
To Enable or Not to Enable WAN?
So, now we come to the crux of the issue. Should you enable WAN blocking on your computer?
Well, let’s first take a look at what WAN blocking actually is.
What is WAN Blocking?
Most routers provided by ISPs will come default set to block WAN traffic to your LAN. In essence, WAN blocking keeps external internet traffic from entering your LAN.
When you open up port forwarding (disable WAN blocking), YOU ALLOW THE ENTIRE INTERNET to potentially redirect itself to one of the internal IP addresses of your LAN.
Allowing the internet to access your local area network gives them access to your router’s GUI (Graphic User Interface) or online settings, as well as its ICMP: Internet Router Discovery Protocol.
The ICMP is the protocol whereby your computer accesses the internet via the router.
Access to the ICMP would allow an internet vagrant to use your router to reconnect themselves to the internet.
In addition, many routers use NAT (Network Address Translation), otherwise known as “masquerading.”
So, What is NAT “Masquerading?”
With NAT, your router connects to the internet and acts like every computer on your LAN is the exact same IP address (let’s not cover IP addresses here, but you can check those out here).
In other words, so-called NAT “masquerading” disguises your LAN and makes it seem like a single device is accessing the internet.
Even if everyone in the family is currently connected—let’s say browsing Amazon for woolen socks, playing Minecraft, and scrolling through Instagram. It doesn’t matter! Your router will pretend like all that disparate traffic is originating from a single device.
Okay, but why is that useful?
Actually, NAT “masquerading” was developed for entirely different uses. Still, it works excellently for security: if no hackers can even see that a LAN exists, it’s a lot less appealing for them to try to hack a single device.
Most hackers want to go for nice and meaty LANs. If your router is acting like a single device on the internet, the vast majority of hackers stay clear.
Why Would I Use WAN Blocking?
This is the issue: most routers come set to default block WAN traffic because security is much higher when WAN blocking is disabled.
Unless you’re hoping to operate a WAN or, for example, are operating servers for which external traffic needs access, there’s no reason to enable external WAN connection.
Generally speaking, if you’re reading this article, the advice is simple: ENABLE WAN blocking on your router.
Many router owners (probably everyone who is reading this article now) also enable WAN ping blocking. This is a handy measure that can add extra security.
What is WAN Ping Blocking?
Wait, wait, wait. Back up. What is a WAN Ping?
WAN Ping: What?
A WAN ping is essentially an attempt by external traffic to access a WAP or router. If WAN pinging is enabled, we can think of our router as a bicyclist in the night.
With WAN pinging enabled, the bicyclist has a headlamp on. He or she says, “here I am, world!”
Without WAN pinging enabled, the biker remains stealthy.
What Is Wan Blocking On Router?
Perhaps somewhat contrary to the metaphor, WAN ping blocking is a perfectly safe and even recommended setting for your router.
With WAN ping blocking enabled, it’s difficult for the outside people to locate your LAN; let allow board it and get free internet (or any other kind of mischief).
So, in answer to the question, “what is WAN ping block mode?” Essentially, it’s a way to hide away from hackers. Guests are knocking on the door, but you don’t want to see them. You’re hiding in your room, thinking, “I’m not home. I’m not home.”
How Do You Actually Pronounce WAN?
Unlike our word “wan,” which is pronounced with a vowel sound like the “a” in “father,” WAN is pronounced with an “a” like the vowel in “man.” Likewise with LAN.
Don’t Be Wan, Just Disable WAN
As we have seen in this article, enable WAN connection from external traffic causes, in most cases, more risks than rewards.
If you decide to enable WAN connection from your local home network, any number of hackers or otherwise bad actors can join your LAN and either mooch off you for free internet or devise more devious schemes.
The long and short of it is this: if you want to have maximum security and you’re not running servers from your home, there’s no reason you would need to enable external WAN access.
Enable WAN blocking, enable WAN ping blocking, and allow NAT “masquerading.”
With the three options above enabled (remember, typically the default settings on a new router), your network will be extremely secure.

What is WAN blocking?
WAN blocking is a type of internet censorship that is employed by the government or an ISP to block certain content. The term “WAN” stands for Wide Area Network and this type of censorship is used to prevent access to websites and other content from outside sources. Typically, these blocks are imposed on Internet Service Providers and other service providers and they work by inspecting the packets and looking at the address information in them.
WAN blocking can be done either through domain name system (DNS) filtering or packet filtering techniques. With DNS filtering, the ISP looks up all packets that are coming in for IP addresses and filters them by their domain name. Packet filtering is when packets are looked at to see what protocol they carry, where they come from, and where they are going. If the traffic matches certain criteria set up by the internet service provider or government agency, then the packets are dropped or blocked completely.
How many types of WAN blocking are there?
There are 3 different types of WAN blocking: IP blocking, MAC address filtering, and IP Address Filtering.
IP blocking is a form of WAN blocking that targets a specific device by looking at its IP address. In order to block a device, the system administrator must determine that device’s IP address and then add it to a list. During this process, the administrator will also select how long that device is to be blocked. This could be anywhere from 1 minute up to several hours or even indefinitely.
MAC address filtering is another form of WAN blocking that allows a system administrator to block a device by looking at its MAC address. In order to do this, the administrator must first input the MAC addresses of all devices allowed on the network as well as those which are not allowed. The blocking will take place based on whichever category the device falls into. If the device is not in that category, it will be allowed access to the network.
The last form of WAN blocking is IP address filtering, which can block an IP address from accessing a network by looking at its IP address. During this process, the administrator must also input how long it should be blocked for or whether or not a specific time should be used instead. If it is to be blocked indefinitely, the administrator will have to manually unblock it for as long as they desire.
Why would any company need to use it?
A company might want to use this technology for security reasons. For example, if people are using the wifi for the internet, there may be malware on the network that could harm an organization’s system.
If a user is in a sensitive area of the network, they might not want other users on the same wifi to see what they are doing. It’s also important to note that many companies don’t allow access from outside the internet during business hours. If it turns out a user isn’t using the company wifi when they should be, it helps them enforce that rule.
An organization may not want sensitive documents being sent out or received during business hours. If there are employees that need to have access outside of normal working hours, blocking WAN traffic can help allow them to do so while still maintaining security for the rest of the organization.
When should I use it?
There are two times in which you would use a WAN block:
1) For protection against hackers- when networks are linked to the Internet, they are vulnerable to attacks by hackers. As the networks are much more vulnerable, WAN blocking is used to provide protection.
2) To throttle bandwidth for an individual- LAN users may also be able to benefit from the use of this function. This is because it can help control usage when there are many people in one location or office.
Conclusion
WAN blocking is a technique that prevents people from accessing websites, applications, and other content on your network. WAN blocking can be useful for companies who want to block specific sites or apps during certain hours of the day or week. In some cases, an organization might need to do this in order to comply with laws such as COPPA (Children’s Online Privacy Protection Act) which requires parental consent before collecting personal data from children under 13 years old. Some organizations believe they may have legitimate reasons for needing to prohibit access outside their physical location using WAN blocking techniques so employees are more productive at work. WAN blocking is not the same as WAN optimization, but it can be combined with WAN optimization.
What is WAN Blocking?
In today’s connected world, businesses rely heavily on wide area networks (WANs) to enable communication and collaboration across multiple locations. However, the open nature of WANs can also leave them vulnerable to security breaches and unauthorized access. This is where WAN blocking comes into play.
To maximize the benefits of WAN blocking, businesses should follow best practices such as proper configuration and implementation, regular maintenance and monitoring, and effective communication with end-users. By doing so, businesses can ensure that their networks remain secure and optimized for performance while also providing a positive user experience.
Overall, WAN blocking plays a critical role in protecting modern networks from various security threats. As businesses continue to rely on WANs for their day-to-day operations, it is vital to implement effective WAN-blocking strategies to mitigate risks and ensure business continuity.
What is WAN Blocking?
WAN blocking refers to selectively blocking certain types of network traffic, whether specific ports, IP addresses, or domains. The main purpose of WAN blocking is to enhance network security and prevent unauthorized access, which can potentially compromise sensitive data and resources.
In addition to security benefits, WAN blocking also provides privacy and network performance advantages. By restricting access to certain websites or applications, businesses can ensure that employees are only accessing authorized resources and prevent data leaks. Moreover, WAN blocking can also improve network performance by reducing congestion and prioritizing critical applications.
However, WAN blocking has some drawbacks, including limited access to specific websites and reduced user convenience. Finding and resolving issues related to WAN blocking can also be challenging, requiring expert knowledge and resources.
Types of WAN Blocking
Businesses can implement several types of WAN blocking techniques to enhance network security and control. Here are the most common ones:
In summary, implementing different types of WAN blocking techniques can help businesses reduce the risk of security breaches and ensure compliance with regulatory requirements. However, it’s essential to implement these techniques properly and regularly review and update them to ensure they remain effective against emerging threats.
Port Blocking
Port blocking involves closing specific ports on a network to prevent unauthorized access to certain applications or services. Different types of traffic use different ports, and attackers more commonly target some than others. By blocking unnecessary ports, businesses can reduce the risk of security breaches and minimize the attack surface of their network.
For example, businesses can block access to port 25, commonly used for sending emails, to prevent spam and malware attacks. Similarly, blocking ports commonly used by peer-to-peer file-sharing applications or gaming platforms can prevent excessive bandwidth consumption and reduce the risk of network congestion.
IP Blocking
IP blocking is a technique used to restrict access to network resources based on the source or destination IP address. This can be useful for preventing unauthorized access to critical resources or blocking traffic from known malicious IP addresses.
For example, businesses can use IP blocking to block traffic from countries or regions where they don’t do business or to restrict access to resources for certain groups of users. IP blocking can also block traffic from known malicious IP addresses or restrict access to certain resources based on IP addresses.
DNS Blocking
DNS blocking involves blocking traffic based on domain names or URLs. This technique can prevent access to known malicious or inappropriate websites or restrict access to certain websites for compliance reasons.
For example, businesses can use DNS blocking to prevent employees from accessing websites that violate company policies, such as social media or gambling sites. DNS blocking can also prevent access to known phishing or malware distribution sites.
Benefits of WAN Blocking
WAN blocking can provide several benefits for businesses, including enhanced security, improved privacy, and better network performance. Here are the key benefits of implementing WAN blocking:
- Enhanced Security: The primary benefit of WAN blocking is enhanced security. By selectively blocking certain types of network traffic, businesses can prevent unauthorized access and mitigate various security risks, including malware attacks, data breaches, and phishing scams.
WAN blocking can also help businesses comply with regulatory requirements related to data privacy and security. By restricting access to certain websites or applications, businesses can ensure that employees are only accessing authorized resources and prevent data leaks.
- Improved Privacy: WAN blocking can also enhance privacy by blocking access to websites or applications that collect and use personal data without consent. By implementing DNS blocking or IP blocking, businesses can prevent employees from accessing websites or applications that are known to violate privacy laws or company policies.
- Better Network Performance: WAN blocking can also improve network performance by reducing congestion and prioritizing critical applications. By blocking non-essential traffic or limiting bandwidth for certain applications, businesses can ensure that their networks remain optimized for critical operations and minimize the risk of slowdowns or outages.
Implementing WAN blocking can provide businesses with various security, privacy, and performance benefits.
However, it’s crucial to balance these benefits against potential drawbacks, such as limitations on user convenience and the need for expert knowledge and resources to implement and maintain effective WAN blocking strategies.
Drawbacks of WAN Blocking
While WAN blocking can provide several benefits for businesses, some potential drawbacks should be considered before implementing these techniques. Here are some of the key drawbacks of WAN blocking:
- Limitations on User Convenience: One of the main drawbacks of WAN blocking is that it can limit user convenience by restricting access to certain websites, applications, or services. While this can enhance security and privacy, it can also lead to frustration and reduced productivity among employees who need access to these resources to perform their jobs effectively.
To mitigate this issue, businesses can implement exceptions or workarounds for specific users or departments that require access to blocked resources. However, this can increase the complexity and cost of implementing and maintaining WAN blocking strategies.
- Need for Expert Knowledge and Resources: Implementing effective WAN blocking strategies requires specialized knowledge and resources, including expertise in network security, traffic analysis, and regulatory compliance.
