Testing routers with firewalk


The firewalk tool is a network security reconnaissance tool that helps us figure out whether our routers are actually doing the job they are supposed to do. It attempts to find what protocols a router/firewall will allow and what it will block.

This tool is incredibly useful during pentesting to verify and validate firewall policies in a corporate environment.

How to do it...

The following is the recipe for using firewalk:

  1. If firewalk is not found, we can install it using:
apt install firewalk
  1. We can use the following command to run firewalk:
firewalk -S1-23 -i eth0 192.168.1.1 192.168.10.1 

The following screenshot shows the output of the preceding command:

How it works...

In the preceding command, -i is for specifying the network interface, -S is for specifying the port numbers we want to test, and the next two are the router's IP address and the host's IP address that we want to check against our router.

Note

Nmap also includes a script to perform firewalk. More information...
