I am developing client/server applications and need to test them on Internet environment. However, I only have one PC without connecting the public internet, so I have a plan to simulate a virtual internet environment on my PC.

I think I will install the virtual machines for my purpose, but I can install only one machine because of my slowly PC.

At the moment, my PC has 2 machines: the host machine (use Windows XP) & the virtual machine (use Windows Server 2003 Ent). Each machine will have 2 network adapter (host-only & internal), and in 2 network adapters, the internal adapter is private on each machine, and host-only adapters are connected together.

With Windows 2003, routing server is ok, but I wonder on Windows XP, are there any routing server product?

Please help me. Thanks.
