First of all, you might want to upgrade the kernel of your Linux
firewall to version 2.4.x and start using iptables instead of ipchains.
Ipchains is not capable of stateful firewalling so it's really a bit
outdated piece of software now. Rule syntax of iptables is very similar
to ipchains, so it souldn't be too difficult to learn.
Check out these:
iptables/netfilter project home page
(netfilter is iptable's other name...=)
Linux kernel archives
Hope this helps you!
