Mikrotik-Mark-Id and Mangle Rules

Hello!, I’m using a routerboard for ending PPP sessions from PPPoE Clients.
Those clients get validated using radius.

Question:
It is possible to mark PPP trafic from radius using Mikrotik-Mark-Id and then do something identifying this traffic with the Packet Mark attribute (for example to use in a Queue tree or in a Firewall rule)…

I have tested it, assigning a certain “Mikrotik-Mark-Id” from radius and then trying to identity the traffic from this session with mangle, but the traffic don’t match the rule I created in mangle.

Any ideas?
