For as far as I remember, this hack works really well when eth0 and 
eth0.30 are not in the same bridge (br0/br1). Anyway, I cannot think of 
a good reason for it not to work in a single bridge.

Try and dig around with ebtable, using the logging feature. Im' pretty 
sure it works, but does not have a bridge available here to test.

I googled around to try and find the original web page where a learned 
this hack, but without any success. You can try, searching for 
ebtables+BROUTING+DROP+802_1Q+vlan-id and so on...
