Ipchains is a Linux-based firewalling tool that was used to control incoming and outgoing network traffic on a system. It was introduced in the mid-1990s and served as an improvement over earlier tools like "ipfw" (IP Firewall). Ipchains provided a way to implement rules for packet filtering, network address translation (NAT), and other firewall-related functionalities.
