First of all a quick diagram of my current network:

Basically I am trying to get XBox A and XBox B to talk to eachother in system link games such as Halo over the LAN. The problem is that XBox B is the otherside of a wireless connection, and the only link to the main LAN is via a wireless PCI card in the PC there. I figured I had 2 obvious choices, to either get another AP and hub switch to bridge the 2 LANs, or install another NIC in the PC and connect it to XBox B via a X-Over cable. I vouched for the latter basically because I already have the hardware, and no money to buy another AP and hub

In theory this should work, but my main problem is configuring the Win2K PC connected to XBox B so that it passes the connection to the LAN on the otherside of the wireless link, whilst keeping XBox B on the same subnet/IP range as XBox A. Sofar I have tried setting up an IP bridge between the NIC and the wireless card using this software:

I also tried using Win2K connection sharing on the wireless card, but of course this put XBox B on a different subnet/IP range. As a last ditch attempt I tried switching on IP forwarding in the Win2K registry, but that did squat all also. Has anyone got any other suggestions, or know of some handy windows software which will do this for me? Just for the record only XBox A is modded to run other software.
