PMFirewall is an Ipchains Firewall and Masquerading Configuration Utility for Linux. It is designed to allow a beginner to build a custom firewall with little or no ipchains experience. This firewall should work for most Workstations, Servers, and Dual NIC routers using either a dialup or LAN setup. It is restrictive to outside attacks while still being as transparent as possible to those inside.
