Porting kernel 2.4 iptables script to 2.6

[Robert L Cochran]

I have an old firewall script which was originally adapted from one 
provided in the book "Linux Firewalls, 2nd Edition". The script is 
running on a Red Hat 9 machine with a 2.4 kernel. I've built a new 
firewall machine running the latest Fedora Core 4. The script doesn't 
work on this machine. If I could be pointed to a script that can be 
customized to my needs and will work on Fedora Core 4, I would be most 
grateful. I am also willing to post my current script for suggestions.

Thanks a lot!
