iptables-firewall-0.99-beta.tar.gz

iptables-firewall, like its older cousin ipchains-firewall, is an easily-configurable shell script to establish NAT and firewalling rules using iptables. The script self-configures out of the box for IP addresses, netmasks, and interfaces. All that is needed is a commandline specification of external and internal interface names. It automatically determines type of firewall to set up (standalone, routing, or NAT) based on interface IP addresses. The distribution also includes a copy of midentd, to enable identd over the masqueraded network.
