If I have understood your question, or even part of it, I think that we are 
using NoCat for the same sort of thing ... between APs and a router.

So NoCat does NOT route but instead acts as a bridge (only).

I think the key steps I took (as a nocat newbie) were :-

1) set up a bridge device (eg br0) containing your two ethernet interfaces
   and assign any IP address to br0 instead of eth0 or eth1

2) configure nocat to use br0 as the "external device" *and* as the "internal 
device" (don't mention eth0/1)

3) enable "RouteOnly  1" - confusingly (to me) this *stops* nocat from acting 
in a routing mode!

This seemed to work for us but I might be wrong!
