You should either attached a bridge to a vlan device or stack a vlan
device on the bridge port depending on what you are trying to achieve.

The bridge handler takes all packets of the device that it is attached
to, so having a vlan also attached to the same device will not work.
You may get different results on older kernels depending on what NIC
you were using but that was a bug.

Hi and thanks for your reply

I tried that.

I had under 2.6.36.3 following combination:

eth1 in br0 ->  all traffic without vlan id
eth1.3 ->  traffic with vlan 3

with 2.6.37 i should do the following
eth1 in br0 ->  traffic w/o vlans
and br0.3 ->  traffic with vlan id 3

But still there is no rx for vlan 3.
Any suggestions? Or am i missing something?

I think you should have a look at ebtables command, in particular, the BROUTING chain of broute table. If this chain ask the packet to be dropped, then bridge will ignore it and give a chance to the upper layer to use it. Upper layer might be IP, or in your particular setup, VLAN.

HTH,

In order for eth1.3 to receive the traffic with VLANID=3, while having the bridge get everything else, you should add an entry to the
