Mikrotik, will it be possible to make qos on the bridge in the proposed configuration?

Question

Computer networks

I will not draw a diagram, the configuration is simple, I will write in words.
Routerboard 2011iL. The ether3 port receives a LAN from the switch, where all clients are connected. Ports ether1, ether2 are combined into softbridge bridge1. The provider’s uplink comes to ether1, we are given a small subnet of white addresses. REAL_IP1 is assigned to bridge1, through which clients will natom go to the Internet. The ether2 port goes to the switch in order to be able to directly issue white IPs to some machines. One of these machines is the asterisk telephony server, let REAL_IP2 be assigned to it. I plan to give it two vlans through the switch, - the local network and the provider's network (REAL_IP2).
And the question is simple. It will be necessary to make traffic from the asterisk to the Internet and back a priority, just let it go first. The clients going through nat - in the second. I'm not sure if it will be possible to do it, because in fact it will be traffic through the bridge .. Or does it matter what the Mikrotik does, the main thing is to mark it correctly in the ip firewall and put it in the queue?

Answer 1

In theory, you need to enable the firewall in the properties of the bridge and correctly catch traffic. It is better to try, I could be wrong (I did not do this myself).
