This is driving me mad ….
All the different traffic flows are being sent to the proper queues based on the related rules, that is a fact.
But beyond that, it seems that the queues respective priority is not taken in account :(
-> I added the following rule in order to prioritize ICMP traffic
Proto Source Port Destination Port Gateway Queue
ICMP high_priority_pc1 * * * * qVoIP
-> without any traffic on the line, ping requests to external IP is around 40ms.
-> with download traffic originating from low_priority_pc2, average ping requests response time is around 150ms , despite being passed to the highest priority (7) queue.
I'm lost ….
