This is not what these Virtual Circuits are - the VCs I mention are ATM
vc's, not 'bridging tunnels'.

Well, you can use a tunnel, it's just that you want a 'bridging tunnel',
that appears by magic so to speak. Basically you are then a two-port
repeater with a long bit in the middle.

Now, is this possible? I think it is, I'm just not entire sure how. 

Perhaps a proxy-arping pseudo bridge does what you want? In that case ARPs
are not transmitted over your tunnel, but your tunnel device reacts to ARP
requests for hosts it knows about on the other side.

If you want a real bridge, you should find a way to create a 'virtual
interface' that lives on the remote host, and run a bridge between your
regular interface and the 'virtual long distance' one.

Perhaps this is possible.

bert
