I am ivestigating queues right now.
I have a subnet I want to lower the internet-access priorities of. So I set up a connection mark ('Learn ROuterOS' Dennis Burgess writes that this less CPU intensive as the mangle has to only match the new connection state and then all following packets belonging to that connection will inherit the mark, saving CPU time).
However, in the Queue Tree, I see only a 'packet mark' option, not a 'connection-mark'.
Does that mean that if I want to use the queues i have to change my mangle rules to match every packet and set a packet-mark?
