'''Linux IP Firewalling Chains''', normally called '''ipchains''', is [[free software]] to control the [[packet filter]] or [[firewall (networking)|firewall]] capabilities in the 2.2 series of [[Linux kernel]]s. It superseded [[ipfirewall]] (managed by '''ipfwadm''' command), but was replaced by [[iptables]] in the 2.4 series. Unlike iptables, ipchains is [[Stateful firewall|stateless]].
'''ipchains''' is a [[free software]] based [[firewall (networking)|firewall]] for [[Linux]]. It is a rewrite of Linux's previous [[IPv4]] firewalling [[code]], [[ipfwadm]]. In Linux 2.2, ipchains is required to administer the IP packet filters. ipchains was written because the older IPv4 firewall code used in Linux 2.0 did not work with IP fragments and didn't allow for specification of protocols other than [[Transmission Control Protocol|TCP]], [[User Datagram Protocol|UDP]], and [[Internet Control Message Protocol|ICMP]].

This newer ipchains was required to manage the [[packet filter]] in [[Linux kernel]]s starting with version 2.1.102 (which was a 2.2 development release). Patches are also available to add ipchains to 2.0 and earlier 2.1 series kernels. Improvements include larger maxima for packet [[counting]], filtering for [[IP fragmentation|fragmented packets]] and a wider range of [[protocol (computing)|protocols]], and the ability to match packets based on the inverse of a rule.<ref>{{cite web | url = http://people.netfilter.org/~rusty/ipchains/HOWTO-1.html | title = Linux IPCHAINS-HOWTO | last = Russell | first = Rusty | edition = version 1.0.8 | date = 2000-07-04 | accessdate = 2009-02-08 | url-status = dead | archiveurl = https://web.archive.org/web/20120216060037/http://people.netfilter.org/~rusty/ipchains/HOWTO-1.html | archivedate = 2012-02-16 }}</ref>

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 It superseded ipfirewall (managed by ipfwadm command), but was replaced by iptables in the 2.4 series.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.

It is a rewrite of Linux's previous IPv4 firewall, ipfirewall. This newer ipchains was required to manage the packet filter in Linux kernels starting with version 2.1.102 (which was a 2.2 development release). Patches are also available to add ipchains to 2.0 and earlier 2.1 series kernels. Improvements include larger maxima for packet counting, filtering for fragmented packets and a wider range of protocols, and the ability to match packets based on the inverse of a rule.[1]

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,[2] which was in turn superseded by the nftables system in 2014.
