You'd only use routing if each PC had a public IP address, and one
address was routed (upstream from your pair of machines) to the other.
If you have only one IP address, that address needs to be on the server
with two NICs, and you need to set up a *private* network for the
communication between your two machines.  You'll sort of turn your web
server into a firewall, rather than a router.

To connect to the Internet in general from your desktop, you'll probably
want to run natd.  The man page for natd should be your starting point.
