ferm is a tool to maintain and setup complicated firewall rules. It allows one to reduce the tedious task of carefully inserting rules and chains, thus enabling the firewall administrator to spend more time on developing good rules, and less time on the proper implementation of those rules. These rules will be executed by the preferred kernel interface, such as ipchains and iptables, and in one pass. Firewall rules can also be split into different files and loaded at will.
