About:
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.

Release focus: Minor bugfixes

Changes:
Memory leaks were fixed in ip(6)tables-save/restore. The printout of odd length netmasks was fixed in ip6tables. iptables-save now works properly with condition match, fuzzy match, (inverted) MAC match, the LOG target, and mport match. Invalid port ranges are now checked for by ip6tables UDP match. The ipq_id_t definition in libipq was fixed on "real" 64bit/64bit architectures. Endianness bugs related to ipv6_prefix_length in libip6tc were fixed.

[»] High performance, featureful, firewall
by Robert Marmorstein - Jun 2nd 2006 08:29:35

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.
