How do packets go through Simple Queue Mikrotik?

Question

Mikrotik

How will the Simple Queue behave if there are 2 queues with absolutely identical conditions (or one queue is a special case of the other)? Will the packet hit both queues in sequence?
It is also interesting, will the same behavior be, for example, for dummynet?

Answer 1

Queues behave in the same way as a firewall. The package is compared by conditions from top to bottom. If there is a match, the queue is applied and the packet with the downstream rules is not compared. Therefore, narrower (by conditions) queues should be placed above the more general ones. For example, if you want to assign a certain speed to a subnet, but one IP address from it has a higher or lower speed, then the queue for this IP must be placed above the rule for the subnet. If you have fasttrack connections, they won't be queued. Therefore, either highlight the packets you need in the firewall with the accept action, or disable the fasttrack rule.
Z.Y. In general, in winbox it is easy to understand whether the order of the rules is important or not. Wherever there is a "#" in the header of the first line, the order is important.
