Hi
I dont know if this is possible, or how to do it. Whatever i try, i somehow manage to bring down our AP 
What i try to do:
I have a bridged client side unit, mode is station. The goal is to have the mikrotik client router transparent.
What is the main problem, is that i need everything that goes out of the antenna to the AP, to be tagged with vlan 2910.
This is so the computer/router/whatever that is connected to the eth of the antenna, gets traffic from the correct network.
If the client side tags the vlans, then the ap will pass it along to a cisco, wich will send it to the right network.
This is probably easy, but i have not much experience with RouterOS, and i would deeply appreciate some help 
Thanx
