The only way I can think of would be to install two extra network
ports. One will connect to the client network, two will connect to a
separate network (either use a crossover cable or a switch - but it
MUST be separate from the client network). Not sure if you could do
this with a bridging and virtual interfaces instead of real ports.
Bind the relay agent to the client network and one of the other
ports, bind the server to the remaining port.
