IP forwarding on multihomed computer

[f-troop]

I have a multihomed Windows 2000 professional computer.
One NIC is connected to a workgroup and the other NIC is
connected to a DOMAIN. I need the workgroup to have
access to the internet via the multihomed computer. I
have enabled IP routing via the registry on the multihomed
computer and tried to add static routes but the no avail.
Any suggestions?

How do you normally get out to the Internet? You most likely pass through a
NAT box. You need to check your route tables ( use route print ). The
machines in the workgroup can have the professional machine with IP
Forwarding as their default gateway. You then need to make sure that the
other machines know how to get back to that subnet. This can be
accomplished by placing a static route on your NAT ( or however else you get
out to the Internet ) and point the subnet specific route to go through the
professional box as well. this works well in a small topology, when you
start having many routers involved, you will want to have that static route
redistributed.
