Now I wonder why I did not think of so simple an idea! Simply put in a
multi-port NIC card,

Another questions...I put in another network port & I end up with 3
NICs & 3 bridges...One providing Internet access, One providing
routing to virtual hosts and one providing route to ltsp network.

Now, traffic among these three networks will be routed automatically
or do I have to put in some code to enable traffic between these three
networks & internet access to the virtual host & ltsp network?
