A bridge on a stick only works under certian conditions, mainly support by the switch its connected to. Its obviously working for you for a period of time so thats probably ok. Make sure that you dont use scrubbing with pf as the bridge doesn't handle the fragment reassembly at the moment. Can you also try a few things when it stops - flush the bridge table using ifconfig - use tcpdump on the bridge interface to see if its forwarding packets cheers, Andrew
