This should work fine with vlan headers, do you have any indication of
where the problem is? you may need to get packet dumps at the sending
and receiving ends.

Grab a tcpdump at the sending bridge0, sending interface, receiving
interface, receiving bridge0. You can send them to me if you need help
deciphering them.
