Re: [Bridge] Bridging untagged and tagged VLANs

[Simon Barber <simon@superduper.net>]

To do this seamlessly you need a VLAN aware bridge - the kernel has 
separate support for VLAN and bridging, but not integrated. I posted a 
patch a while back to fix this - see here:

http://www.mail-archive.com/bridge@lists.osdl.org/msg01440.html

It was for a 2.4 kernel, but shouldn't take too much work to port to 2.6.
