Not that hard, really. You just look, for each packet, where it came 
from, and then you know which circuit it belongs to. And outgoing, you 
just check which circuit it comes from, and that gives what remote 
address it should be sent to.

My understanding is that for VMS, they usually all are using the same 
port, and this VMS do handle.
