I have been intermittently trying to set up a filtering bridge for a
small network using OBSD 3.6. Installation goes well, but none of the
internal machines can access the outside world or get an IP address from
the router. The network configuration is ISP>cable modem>router/DHCP
server providing non-routable addresses>bridge>switch>internal boxes.

I read in one manual that a crossover cable was needed to connect the
bridge to the internal machine. Is that true? If so, does the
crossover cable go between the switch and the bridge or between the
switch and each internal machine?

Thanks,

G
