I'm not sure if the bridging code is from ET or if it's the
standard FreeBSD but it seems to be standard FreeBSD bridging code.

I've asked Dennis at ETinc the question and his response was:
if you want to route from one DLCI to the other then you have to put them
in separate bridge groups with their own subnet. You are creating isolated
segments with the ipmap functionality...the mechanism is designed for end
users who get 1 or 2 addresses.
You COULD fix the O/S to route back to the same interface, but I dont know
how complicated that would be. I dont think there is an easy way to
disable
split-horizon.
