ipchains-firewall 1.7.1 released

ipchains-firewall is an easily-configurable shell script to establish masquerading and firewalling rules using ipchains. 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 masquerading) based on interface IP addresses.
