Seems like you're facing the problem where bridge0 inherits its MAC from
the 'wan' interface.  Try to specify bridge0's MAC explicitely (via
ifconfig's 'link XX:XX:XX:XX:XX:XX' arguments); you can use some random
MAC, for example the one that is generated at the system's bootup for
bridge0 (example from one of my hosts):
-----
$ dmesg | grep bridge0 | grep Ethernet
bridge0: Ethernet address: 2e:13:01:19:11:66
-----
May be this will help you to work out your problems.

If so, then you'll probably need sys/net/if_bridge.c revision 1.117,
  http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/src/sys/net/if_bridge.c?rev=1.117;content-type=text%2Fplain

If this won't help, I'll try to think a bit more about this issue ;))
