Jay's Iptables Firewall is a bash script that lets you easily install and configure a firewall on a Linux system.





Jay's Iptables Firewall is a bash script that lets you 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 since support for multiple interfaces was added.

The basic features are sharing internet over a LAN, forwarding TCP or UDP ports over the LAN (for programs which require to be directly connected to Internet (to receive files by ICQ, eDonkey, KaZaA, ...)), log for prohibited accesses and more.

The firewall is very restrictive "All incoming traffic is blocked except ...". It carries out a filtering of the IP, TCP, UDP, and ICMP headers. Protect from DDOS (Distributed Denial Of Services) attacks, Smurf attacks (participation to a DDOS), Invalid IP sources and much more).

The configuration of the firewall is assisted by an interactive configuration tool.

You should be able to use the "firewall-config.pl" script for a interactive configuration, or use "firewall-config.pl -g" to generate a empty configuration's file and configure it by hand.
