While this p2p route will work ok for the first Linux guest, you'll get in trouble when you add another. Define an entire subnet to for use on the virtual hipersocket LAN. 2) The symptom you describe usually indicates that the external routers do not know to route 10.8.1.93 to 10.1.1.90. So, packets find their way out into the network just fine, but they can't find their way back again.
