Assuming your multi-player games are all local network and not internet
server based, a very easy way to do that would be to have the M$ boxes
boot with a different network address.  Use one that would not be on the
same subnet as the linux boxen and thus would never be able to go to the
internet via your firewall.

If they are internet based then blocking other internet access seems
difficult if not impossible.

Using option 1 above would be tricky unless one OS (M$) used static IPs
and the other used DHCP.
