it should work, slightly suboptimally at the moment (i.e. it puts all
ethernet interfaces in promisc mode).

I have some mods to let you do bridging only on clusters of interfaces,
but don't know when they will be ready for commit. In the meantime, if
the above is a problem for you, the best approach would be to skip your
"external" interface in the bridging loop.

correct: one address to the card connection to the outside, one address
