You don't mean a physical router do you? Is there a way to software route the
two networks together since they are both on the same physical computer. I'm
afraid I'm not to savvy on the fine points of networking.

How did you did you get "its own virtual interface"? DHCP gives an address
that is on a different subnet than my local network. I tried giving it a
fixed IP address on my subnet and lost internet connection and it didn't seem
to work anyway as far as accessing the peer network.

The big difference is that I don't have the Tap driver loaded. I've tried,
albeit with the 1.56 version of Vbox, and it kills my normal networking and
makes the MPTS object very slow, to the point of not working at all. The only
way I could fix it was to boot to another system and the remove the driver
files so the next boot couldn't load the driver. This happened on RC7 as well
as RC4.

I also have the NetBIOS loaded to get the peer network working between two
eCS computers. NetBIOS over TCPIP is loaded by default during install.

The only networking Vbox is using here is the NAT driver.

Maybe I'm missing some key point that will make it work, but so far no go
here.
