ferm Description

ferm is a tool to maintain and setup complicated firewall rules. ferm is a tool to maintain and setup complicated firewall rules. It allows one to reduce the sometime nasty 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.Ferm is written in perl, so it requires perl5, and one of the kernel firewall programs (ipchains/iptables/ipfwadm) to work, although you may test firewall rule generation on any platform that supports perl.For a good understanding how ferm works: check out the examples listed on top of this page. What's New in This Release: · support negation in mark/connmark · support negation in set · added automatic variable $FILENAME · allow @subchain as the first keyword in a closure · don't allow semicolon after empty rule · enable @include to run a program · removed superfluous tokens from error message · create a new stack frame for @subchain (fixes $CHAIN)
