Forward all traffic from wan to lan?

This seems like a simple problem, but I'll be %^%^ if I can figure it
out.

Here's the scenario:

I have a server running on a windows XP box (a game server). The box
has 2 NICs, one with a lan address (192.168.0.xxx), the other outside
the firewall with a wan address (say 23.23.200.200).

I want to be able to connect to the server locally with my lan machines
(the server 'binds' to the local IP address), but let outside users use
the wan address. The game server does not support multiple net
interfaces.

Is there a way to get XP to forward (bi-directional) traffic from the
WAN interface so it appears to be coming from the LAN interface for the
game server? It needs to be tcp & UDP traffic.

Any help will be *most* appreciated.

Thanks
Rob

Though a better arrangement might be to use a NAT router for the Internet
connection, and set the gamesever as the DMZ.

Whichever you use, the source IP will still annouce itself as its 'rea'l IP
of course. That might or might not be acceptable if the gameserver is
designed to allow access from only one subnet-mask. It should be OK if there
are no such restrictions built-in.
