Re: Building a Raw Bridge

What you described is a different interface for tx and rx.  What you've drawn is separate tx and rx radios which are melded in the driver and expose a single interface "wan0".  Which is it?  (If the drawing is correct, I don't think you have a problem at all, aside from trying to use two bridges when you need only one)

I'm having trouble figuring out how to make a bridge that does not block
forwarding of packets when there is no receive channel in the same

another circuit. The two directions are on two different radios. I would
think this would be like the response given to someone in July 2007
about setting a "hub" mode by setting the aging timer to 0. I tried that
and it did not work.

I also tried a few schemes with ebtables without success either. Is
there some relatively easy way to make the bridge forward everything and
not cut off the transmit after a single packet?

The WAN side uses a synchronous serial interface to the radios for
satellite communications. The other end uses a single radio and bridge.
