Self2WAN ICMP Type B Detected! 5 Fixes

NETGEAR is responsible for producing some of the most cutting-edge networking and communication devices and equipment. Their products are renowned throughout the entire world for being exceptionally secure, dependable, and effective in their respective fields. Having said that, NETGEAR provides an error log in almost all of their most recent routers and modems, which enables you to identify any faults that you could be dealing with and that are making your experience with networking more difficult. It is highly advised that you check the error logs of your computer on a regular basis to ensure that there are no problems with your network or your router.

Some individuals have the habit of checking the error log of their router on occasion, and when they do so and read an error that states, “Self2WAN ICMP Type B Detected,” it can be concerning because it appears to be a warning about a virus. This article provides a comprehensive explanation of what it implies.

Self2WAN ICMP Type B Detected! What Does it Mean?

If you see an error message that reads “Self2WAN ICMP Type B Detected,” for example, it indicates that there is no reason for you to be concerned in the first place. The presence of an error message in your log indicates that your firewall is operating as it should and that you are protected from any ICMP threat that may be posed to your router. However, the first thing you need to know is that you are, in fact, safe from a danger that attempted to access your private information. This notice in the error log indicates that there has been an effort by a third party to access the traffic and data on your network; hence, you need to take the necessary precautions to ensure that this situation will never arise again. Here are several potential solutions to the problem, which I have outlined below.

1) Make sure Remote Access is working.

If you need to use remote access for any reason, whether it be for official business or to fix a problem, you can use it for anything you need. That is likely to cause the router to display this error. You need to check the time that was recorded in the error log and compare it to the time that you used remote access. If the two times are identical, you can be certain that the issue was caused by the remote access you were utilising, and there have been no attempts by a third party to gain unauthorised access to either your router or your computer. You can have peace of mind knowing that this issue was your fault.

2) Perform a firmware update on your router.

If you think that the times don’t add up or whether you haven’t been utilising any kind of remote access in recent times, the first thing you need to do is check to see if there have been any changes released for the firmware of your router. An outmoded firmware has a greater risk of developing faults over time, which increases the likelihood that it will inadvertently cause certain types of mistakes. After successfully upgrading the firmware on your router, you will be able to check the error logs on a regular basis in order to verify that the problem will not recur.

3) Verify that your antivirus and firewall settings are correct.

This error can also be logged on your router if you are using outdated security software, such as a firewall or antivirus programme, on the devices you are using. You have an obligation to check that all of your anti-virus software and firewalls are running the most recent versions and are properly configured. By doing this, you will prevent your router from displaying errors of the same kind in the future. However, if the error continues to show up even after you have checked all of the steps listed above, you will need to perform some checks that are more in-depth, such as.

4) Reset your router

There is also the potential that the settings on your router or any component of the hardware are inadvertently causing this error to be logged in the error log of your router. If this is the case, you will need to return your router to the settings it had when it was first manufactured; doing so will effectively eliminate the issue once and for all. Finding the small reset button at the back of your router, which is positioned next to the power button, is a necessary step in the process of resetting your router. Hold it down for ten to fifteen seconds until the lights on your router start blinking again, and it will work just as well as it did when it was brand new. When you reset your router, you will lose all of its settings, and you will need to reconfigure it again according to your specific preferences and needs. This is the only thing you need to bear in mind before you begin the process of resetting your router.

5) Ask the administrator of the network

In the event that none of the aforementioned methods resolves the issue for you, it is necessary that you seek the assistance of a network administrator. This person will be able to investigate more into your network, properly diagnose the issue, and assist you in finding a solution to the issue. Even if it is not a major issue, you should only consider this option if you have exhausted all other possibilities.
