Vlan+Simple LAN over wireless...

Here is a simple architecture that couldn´t made work.
I just want to trunk tugged and untagged frames over the same links, to reach the client with a VLAN, over a bridged based network.
The links are working fine, the Public Internet Access is working fine. I want to use this piece of network as transpor for the VLAN.
Any sugestion?
