I have done some previous investigation around using tproxy4 code on a 
bridge interface.  I found that the bridge code clobbers the dst route 
entry added by tproxy4 during prerouting, and that packets processed by 
tproxy destined for the localhost need to be marked with a packet type 
of PACKET_HOST otherwise they are dropped higher up the stack.

I don't have a patch right now, but I can get you a diff of the bridge 
code changes needed to make this work if you are interested.  The 
changes are fairly minor.
