    Respond Icmp Echo (Ping) Request From Wan: SHOULD I ALLOW A PING FROM WAN?

    One of the most common questions we receive is whether or not a company should allow ping requests from Wan. The short answer is that it depends on many factors, but we typically recommend allowing pings from Wan in most cases. This post will explore why and offer some tips on how to decide when and whether to allow ping requests from Wan.

    What is Icmp Echo (Ping)?

    Icmp Echo (Ping) is a network troubleshooting tool used to determine if the device on the other side of the network is responding. This can be useful when trying to diagnose networking issues. The ping command sends an ICMP echo request and waits for a response. If the ping command does not receive a response withintimeout, it assumes that the device is not responding and will halt further execution of the ping command.

    The use of icmp echo request can be dangerous because it allows someone on your network toping your router or another device and potentially spy on your traffic.

    It’s important to consider whether allowing a ping from Wan is necessary before performing it. Ping commands are easily blocked by firewalls, so make sure you have permission to send pings from Wan before using this tool. Additionally, allow time for devices on both sides of thewan connection to respond—pinging too often can cause unexpected results.

    Why would you want to allow a Ping from Wan?

    There are many reasons why you might want to allow a Ping from Wan. For example, if your Wan is the only way in or out of a certain area, you might want to allow Ping traffic in order to ensure that devices within the Wan can reach each other. Additionally, if your Wan is also acting as a DHCP server, you might want to allow Ping requests so that devices can find their home networks.

    While there are certainly legitimate reasons to allow Ping traffic from Wan, there are also risks associated with allowing ping requests. If an attacker is able to spoof a ping request from your Wan, they could potentially access sensitive information or hijack devices on your network. Therefore, it is important to weigh the pros and cons of allowing ping requests before making a decision.

    How do you enable Icmp Echo (Ping)?

    When you are troubleshooting a problem, one of the first things you might do is ping from your computer to the other computer. Ping is a simple way to see if you can reach the other computer. If you ping from your computer to the router, it will also check the router’s status.

    Windows 10 allows you to ping computers on a network using icmp commands. You can use ping or ipconfig /all to view these icmp commands. To enable icmp echo (ping) request on a Windows 10 machine:

    1. Open Control Panel
    2. Click Network and Internet > Network Connections
    3. In the left pane, click Local Area Connection or Ethernet connection that is currently active
    4. Right-click this connection and select Properties
    5. On the General tab, in the Advanced section, click TCP/IP Settings
    6. In the TCP/IPv4 Properties window, under IP settings, click ICMP Settings
    7. Under ICMP Settings, in Enabled items list box, select Echo Request (ping) option

    After enabling this setting, you need to restart your machine for changes take effect.


    Whether you allow a ping from Wan or not is ultimately up to you. However, I would recommend allowing a ping from Wan in order to keep track of your device’s location and health. Ping logs are an excellent way to monitor the health and performance of your devices, as well as finding any issues that may arise on the network.


    As a business owner, it is important to understand the security risks of allowing ping requests from the internet. A ping request is a small packet of data sent by another computer to check if your device is able to respond. Allowing these requests from the WAN (Wide Area Network) could potentially open up your system to malicious attackers.

    In most cases, there is no reason for you to allow a ping request from the WAN side and it should be blocked in your firewall settings. However, if you need this service enabled for legitimate purposes then it can be done securely with proper authentication methods in place. For example, you can use two-factor authentication or public key encryption to ensure that only authorized users are allowed access. Doing so will protect your network against potential attacks while still allowing users on the other end access to services they need.


    🤔 Should I allow a Ping from WAN? 🤔

    This is a question many network administrators ask themselves when setting up their networks. While allowing ICMP Echo (Ping) Requests from WAN can be beneficial in some cases, it can also be a security risk. In this blog, we’ll look at the potential security risks of allowing ICMP Echo (Ping) Requests from WAN, as well as the potential benefits of doing so.

    The main security risk of allowing ICMP Echo (Ping) Requests from WAN is that attackers can use them to identify and map out the network. By sending these requests, they can identify the active machines on the network, as well as the operating systems they are running. This can be used to gain a better understanding of the network and its components, which can then be used to launch targeted attacks.

    On the other hand, there are some potential benefits to allowing ICMP Echo (Ping) Requests from WAN. For one, these requests can be used to test the network’s performance and stability. By sending out a Ping request, you can measure the response time and determine if there are any issues with latency or packet loss. This can help identify any potential problems with the network before they become more serious.

    Ultimately, the decision to allow ICMP Echo (Ping) Requests from WAN should be based on the individual needs of your network. If the potential benefits outweigh the potential risks, then it may be worth allowing these requests. However, if the risks outweigh the benefits, then it may be better to disable them. 🤔
