What mode is iwn0 in?  Access point?  Client?

You can add a wireless client interface to a bridge, but frames sent
with a different source MAC than the wireless NIC's MAC may be dropped
by the access point.  I guess it's possible that the source MAC will be
overwritten with your wireless NIC's MAC; then replies will carry the
wrong destination address.
