Hello,
I have the same question as @cander19.. I have not tried to directly link the 2 machines with a cross-over network cable, as getting to one of them is a real pain.. I have also had no luck with networked play, and like @cander19 all the setting look good.. ip's for the machines are 192.168.1.3 for ID1 and 192.168.1.4 for ID2
