Easy iptables rules editor
Version: 1.3 BetaTired of manually editing iptables rules to make your firewall just work? Given a simple network of a gateway with n external ips, this script will let you firewall off your lan from the rest of the world while performing source and destination NAT for various services. The best part though, is that you don't have to play with iptables rules anymore, just edit the flat files.
Operating System: Linux
Note that I don't maintain this script anymore due to the fact that while it's easy to configure, it's hard to configure for special purposes. It's also not very efficient as it doesn't use any custom chains. Feel free to download it for kicks or just out of curiosity, but if you want it done right, I suggest you pick up a copy of Linux Firewalls and roll a script yourself.
