Is there another resource apart from Netfilter.org and Andreasson? I have some knowledge of TCP/IP, but not much Linux, which Andreasson assumes you have. I can write rulesets which seem to work, but I'd like to understand them a little more. Any pointers? Thanks,
Jay
What's wrong with the tutorials on netfilter.org? Are you missing something particular there?

I recommend "Linux Firewalls", Second Edition by Robert Ziegler. It was published in 2002, but it has coverage of iptables, good examples. You should be able to pick it up used too.
