Feather Linux for firewalls

Tuesday, 15 February 2005, 1:01 PM EST

The firewall infrastructure of GNU/Linux consists of two parts, the kernel (netfilter) and the configuration structure (iptables). In order to build a firewall structure in GNU/Linux, you first need the proper netfilter support, which almost every Linux distribution includes by default.

These rule sets are called chains. To set your rules, you must set up a chain of them to manipulate packets appropriately.
