Jay's Iptables Firewall

Jay's Iptables Firewall is a bash script that allows one to easily install and configure a firewall on a Linux system. It was initially written for use on a home LAN, but can be extend to any type of network. It features support for multiple (external/internal) interfaces, TCP/UDP/ICMP control, masquerading, synflood control, spoofing control, port forwarding from specific interfaces, VPNs, ToS (bandwith managment), denying hosts (IP or MAC address), ZorbIPTraffic, Spyware list IP, Pre/Post scripts, log options, and more. The firewall is able to launch custom iptables rules, and the configuration of the firewall is assisted by an optional, interactive, curses-based Perl script.

        Release Notes: The unclean module has ben removed for kernel 2.6 compatibility. The spyware/deny-IP feature has been optimized (bandwidth may have slowed with too many IPs). The forwarding option allows you to forward some ports from the LAN side. An option for keeping modules loaded after 'stop' has been added. A small bug has been fixed in the 'ping_for_all' feature, and the LAN can now ping your firewall while ping_for_all=0 (default rules for the LAN). A config file has been added for the 'firewall-spy-update.pl' script.
