Firewall configuration review tools

Just wondering if anyone knows of any good firewall configuration review tools that may be available for use with Parrot OS? I know there are commercial tools such as Nipper but i’m after some free tools that can perform a configuration review of a Firewall export file. If anyone can help it would be much appreciated!


hello, I am begginer, but for me I use nftables, rkhunter and unhide.

Thanks for the reply but i’m actually after a tool to perform review of a Firewall export file, i.e. to check the inbound/outbound rules, etc… for an export file, e.g. a Cisco export.

Found something that did the trick, nipper-ng. Just git cloned from the Kali repo to get things going:
