Arno's IPTABLES Firewall Script 2.0.1b Description:
Arno's IPTABLES firewall script was initially written because I needed to protect my single-homed Linux machine at work. I wrote it at the time I couldn't find any script that really satisfied my needs except for one that was written by a guy called 'Seven'. I helped him for several months with the work on his script by suppling patches, reporting bugs etc. In this period I was fortunately also able to master scripting for iptables myself because soon Seven discontinued his work, I never got to even talk to the guy ever again. At that point I decided to continue his work, or actually I started my own branch based on his script. In the summer of 2002 I finally got an ADSL connection at home. Initially I used the iptables firewall that came with the great ADSL4LINUX-package. But it didn't take me long to come to the conclusion that their iptables firewall lacked important features like port-forwarding and flexbility with "trusted hosts" etc.
