Connect the machine to a switch? :-) Your bridge machine should not see traffic
directed towards MACs on other ports on the switch if the switch is working
right. The switch ought to learn which MAC addresses are reachable through the
port your bridge machine is on, and will just deliver the appropriate traffic
There's probably some netgraph trickery that would let you do STP on the bridge
machine as an alternative solution, but I don't know enough about that to advise
you on it....
