Sorry, the configuration shown below is not supported. The HP discless
solution, as it exists today, will not work through gateways which is what
your 360 server now represents. The diskless transport will only work over
one of the LAN cards at a time, in this case the aiesds1 318 and aiesds2 
340 client being served on lan0. The only way to do what you want is to
put the server and all clients on the backbone, assumming that the buildings
are tied together via a bridge or repeater (i.e. not another gateway),
-or- physically extend your lan to the other building (which you specified as
undesirable). Sorry..
