What do you want to do with it? (Remember however, a firewall is a security
device mainly, and isn't really meant to directly protect you from viruses,
trojans, or spam. However, it can help do those, although its main
function is a security device).

Yes, but I would recommend something other than redhat for that, like one of
those distros that is meant specifically for that use. However, you can
use redhat for a gateway if you like...

IPChains should already be installed. I do recommend not using the
graphical firewall config. If you can, uninstall that program, but keep
ipchains, and from there learn how to use IPChains. There are good
articles about using IPChains to do this.
One other thing, however: IPChains is older. I'd recommend downloading
kernel 2.4.23 and IPTables, which is better and more robust. I've never
used ipchains for a gateway/router box, but i've been told that it's better
to use iptables for that use.

Uh, I don't know ipchains, so you'd have to go to www.netfilter.org to ask
them (they have several articles and howto's that will explain)
