Hey guys,
Not sure if this is the proper place to post this question, apologies if it is not.
I’ve been using Mikrotik routers for about a year with great success after many years with Cisco products. The other day I noticed a strange problem. The bytes / packets in the ip firewall / mangle rule were not matching the bytes / packets in the associated queue tree. The rules are for DHCP users and I saw 15 users connected, but did not see any traffic in queue tree. When I checked the firewall and interfaces / torch, saw the traffic.
I deleted / recreated the queue and it worked for a few hours, then stopped working again. No changes were made to the router, but I did upgrade to latest RouterOS which did not fix the problem. I also tried deleting / recreating the mangle rules, creating new queues and nothing seems to work.
Any help, tips, ideas would be greatly appreciated.
Please see screenshots of byte packet mismatch along with the rules / queues.
