What is the easiest way to get Windows XP Professional to act as an NAT
server for only one of its attached host adapters?

Will,

ICS is a Windows XP NAT ROUTER solution - not NAT server. You can
configure ICS
on any one of multiple LAN connections.

ICS isn't all that secure I guess? What's the cheapest commercial NAT
solution that would work on a Windows XP host? Most commercial solutions
are going to be full blown stateless firewalls that require a server OS for
the install, not to mention fairly serious dollars.....

I need the NAT on Windows XP just as a performance tweak on a VMWare virtual
machine used for a non production system. The VMWare built-in NAT
functions work but have terrible performance problems. I can certainly
try ICS, but just hate to lower security on the XP host.

I respectfully disagree with Chuck's comments about ICS being insecure
or straining the resources of the server. In my opinion, ICS, with
the Windows Firewall enabled on the host, is fine, because:

1. The attack that he cites that can kill the Windows firewall has to
come from a computer on the LAN. The attack can't come from the
Internet. See this site for details:

2. In my opinion, ICS puts a negligible load on the host computer. A
typical home broadband router has a much slower processor and much
less memory than an XP ICS host computer. For example, my SMC
Barricade router has a 40 MHz CPU and less than 1 MB of memory. A
computer meeting the absolute minimum requirements or Windows XP is 10
times faster and has 128 times as much memory. A more recent computer
is at least 50 times faster than that router and has at least 256
times as much memory.
