Tools to test the firewall

RouterOS General
1

Anyone know of any good tools or sites to test a firewall? I want to make sure that everything is good and secure.

Thanks in advance!

what exactly you want to test?

basically it is all down to configuration, what is allowed and what is not.

I’m looking for tools that will test for vulnerabilities and report back potential security issues, areas that need attention, etc. Something that will help harden the firewall against most potential threats.

nmap

for that you can simply set up firewall and then use port scanner on routers address to test filters on input chain and then somewhere behind router for forward chain.

that way you will see all the open ports that are potential security issues. and what you have to secure, so port can stay open.

Start by going over your configuration and knowing what you want it to do. After that, I find that “ShieldsUp” from Gibson Research works great for quick tests from “outside” to verify it’s doing what you think it should be.
