IP Masquerading and REDHAT 9

I've got a Dell Pentium Pro server up and running w Redhat 9 and it
has 2 network cards.

My goal is to use the box as my router on a cable connection for my
home network that includes a Win 2000 Server, Win 2000 and Win XP
clients.

I need some 'down and dirty' guide to just get me off of the ground
and running. I've been searching the Web for a couple of weeks and
have found precious little in terms of sources for someone new to Red
Hat. Many of the references that I have found are for older versions
of Red Hat or are technically over my head.

How about it? Is there a source of info or a guide to help me get
started?
