iptables

iptables is built on top of netfilter, the packet alteration framework for Linux 2.4.x and 2.6.x. It is a major rewrite of its predecessor ipchains, and is used to control packet filtering, Network Address Translation (masquerading, portforwarding, transparent proxying), and special effects such as packet mangling.

            High performance, featureful, firewall
            IPtables/Netfilter supports all sorts of advanced features, such as NAT, masquerading, packet redirect, and many others. It also has all sorts of useful matches, such as the STRING match and the ipset module. It is one of the very best stateful firewall systems available.
