You have it half right. You *could* use one card and a hub, but that would
totally defeat a good portion of the usefulness of the linux box - being a
firewall.
So you want 2 nics.
Then configure the linux box to do ip masquerading (also known as NAT) and
as you already said, you just use it as a gateway from the win boxes. It
is the ip masquerading that serves the same purpose as the proxy software
under NT, but just does it in a way that is better/easier for a local lan
to use.
