What about bridged interfaces that have a MAC, but no IP address?  I'm
still trying to figure this one out for a (4.8-R) bridge that's working
fine but still has some issues with ARP confusion and thus repeated ARP
requests from the upstream / outside router, esp regarding broadcast UDP
traffic, where the inside interface has the one IP and thus broadcast
address, for broadcast packets delivered locally to the bridge's IP? 

I realise this is a bridge issue, but it's how it interacts with ARP.

The rest of this is well out of my league, but fascinating reading :)

Cheers, Ian
