Another thing to bear in mind: many commodity VLAN-aware switches cannot 
cope with another device bridging frames between two VLANs, as their address 
databases store {MAC address, VLAN, port} and do not permit duplicate MAC 
addresses.  In my experience (of 3Com managed switches of various models) 
this manifests itself in all manner of bizaare and unexpected ways.  So if 
your "in" interface is connected to a managed switch, expect unpleasantness.

This is not (AFAICT) a bug with the Linux bridging driver, but a design 
limitation of such switches.
