Same way my Bridge do. Or RSX do. You look at the source information for 
each packet received, and match it against your setup circuits for 
receive. For transmit, you know which circuit, and then you can just 
look up what remote end you are supposed to send the packet to.
With UDP you can explicitly say to which destination a packet should be 
sent. No matter if the socket have been bound to something or not. And 
if it hasn't been bound to a remote address, you get all packets from 
anywhere. The receive call can provide the source of the packet.
