I have fxp0 and fxp1 acting as a bridge, fxp0 sees all kinds of > http traffic, napster, IM, etc. but fxp1 sees only multi/broadcast packets. because for unicast traffic, the bridge only forwards those packets for which there are receivers on that interface. Ideally it should do the same for multicast but that is a bit trickier to implement so i decided to leave this out. cheers luigi -----------------------------------+------------------------------------- Luigi RIZZO, luigi@iet.unipi.it .
