That is what I want to do. I have really big dishes for the 5ghz link 
and a good fade margin already. I also have a 2.4ghz card to act as the 
AP with a little panel antenna. What I am confused about is how to set 
the interfaces up using just one board.

The backhaul needs to be bridged, I need to see the MAC address that are 
comming across it. I suppose I could forgo that requirment if it really 
is easier to route it. I can mess with the MAC's at the router at the 
far side of the backhaul. The AP does not need to be bridged but that is 
how I have always done it. So mostly what I need is idea on how 
everything needs to be setup maybe with an example so I can copy it and 
put in my own IP's.

What I have now which is really weird is I have a 2 port WRAP running 
18v PoE acting as a router/AP then another 1 port wrap acting as the 
backhaul. It gets its power from the DC jack off of the two port wrap. 
It is not pretty and needs to be fixed up.
