MikroTik Router Firewall Protecting Your Network From Threats

If you are looking for a way to keep your Mikrotik router secure and block unwanted ICMP requests to the WAN IP, then this guide is for you. In this post, we will show you how to set up a firewall rule on your Mikrotik router to block ICMP requests to the WAN IP.

Step-by-step guide:

Log into your Mikrotik router using your web browser, and navigate to the “Firewall” option in the main menu.
Click on the “Filter Rules” tab to open the rules configuration page.
Click on the “+” button to add a new rule.
In the “General” tab, choose the “drop” action, and set the “Chain” to “input”.
In the “Protocol” tab, choose “icmp” in the “Protocol” field.
In the “Advanced” tab, choose “icmp-request” in the “ICMP Types” field.
Leave all other settings at their default values and click on the “Apply” button to save the new rule.
Your new firewall rule should now be in place, and all incoming ICMP requests will be dropped.

It is important to note that ICMP requests are used by many legitimate network tools and services, such as ping and traceroute. Therefore, blocking all incoming ICMP requests may cause problems with these tools and services. For this reason, it is recommended to only block ICMP requests from external sources, and allow ICMP requests from trusted internal sources.

By following the steps outlined in this guide, you can easily set up a firewall rule to block incoming ICMP requests to the WAN IP on your Mikrotik router. It is important to remember that while blocking all incoming ICMP requests may improve security, it may also cause problems with legitimate network tools and services.
