This may be a question for superuser.com, given its intent, but that site isn't up yet. :)
I'm using my MacBook's Internet sharing to share its Wi-Fi connection with my Xbox 360. This works, and I can see the Internet from the Xbox, which is fine. What I'd like to do is get my Xbox to be able to see my other computers on my main network, so that I can do media sharing. I have a network that is on the 192.168.2.x subnet, and my Internet sharing on my MacBook is set up on the 192.168.20.x subnet. My MacBook obviously can see my media PC over the wireless network. How do I get across the 2 subnets so my Xbox can see my media PC?
