They are doing an interesting Ethernet NAT with the following idea:
Your wireless station has MAC "A" and IP "X"
The virtual machine on the wireless station has MAC "B" and IP "Y"
1) To the outside world both your wireless station and virtual machine
IPs would share the same MAC:
IP "X": MAC "A"
IP "Y": MAC "A" (translated from "B")
2) Every ingress packet coming to your wireless station with the VM's IP
"Y" would have it's MAC changed back
This scheme could provide you connectivity but it's hacky and it
requires you to know the MAC and IP address combination of VM. So IMHO
it's not really everyday mess-free usable.
I'd prefer to have a real routing set up. Simple, fast and reliable.
