Our network looks like this.

The side of PC2 is my side, the PC1 is the neighbors'. PC1 runs XLink messenger in WGN Mode, but only finds the right x-box. When i run xlink on pc2, my pc, it only finds == as expected == my x-box.
The left lan is on subnet 192.168.3.0/255.255.255.0
The wlan is on subnet 192.168.2.0/255.255.255.0
The right lan is on subnet 192.168.1.0/255.255.255.0
Our subnets are routed by PC1 and PC2. My xbox can ping the other one, and of course that xbox can reach mine. We simply cant play together. It seems that xlink messenger has got trouble with multiple subnets.
Or am i wrong with my assumption?
Thanx in advance
btw. replacing that wlan with a regular lan and making this one big subnet is not an option. Why else would we've chosen for expensive wlan if we could
