Eygene,

Thanks very much for this information! I didn't even notice that the bridge
and wan interfaces had the same MAC. I'm at work at the moment, and the box
is at home, but I'll try manually setting the MAC to a value not used by
other interfaces later tonight and see what happens.


Thanks again!
