Ipchains

Linux IP Firewalling Chains, normally called ipchains, is free software to control the packet filter or firewall capabilities in the 2.2 series of Linux kernels. It superseded ipfirewall (managed by ipfwadm command), but was replaced by iptables in the 2.4 series. Unlike iptables, ipchains is stateless. The ipchains suite also included some shell scripts for easier maintenance and to emulate the behavior of the old ipfwadm command. The ipchains software was superseded by the iptables system in Linux kernel 2.4 and above.
