After reading everything I could find online regarding netfilter and iptables, I've come up with a working firewall/masquerade/NAT script using a 2.4.17 kernel. I have attached the file to this message. I know this is incomplete at best, and probably has errors as well, which is why I'm posting it here. I am open to any constructive criticism of this ruleset. I've included comments to explain the intended purpose of each line, and I put several questions inside as well. Thanks in advance, Jeff Bonner
