Thx, Doug
Understood. We need to define some "pass" commands to map the traffic to dedicated queues. We´ve studied the "pf manual" and are not quite sure how the pass actions should look like.
We have already configured the below listed tables in "ipfw.rules".
pass in quick on igb0 from t_allowed to queue allowed
pass in quick on igb0 from t_specialip to queue specialip
pass in quick on igb0 from t_terminals to queue terminals
pass in quick on igb0 from t_freeunlimited to queue freeunlimited
pass in quick on igb0 from t_free to queue free
Any idea what we have missed?

Betreff: Re: Issue using altq_priq unter FreeBSD 11.1 - help needed
You are missing the filtering commands to tell pf which traffic goes in which queue. Here is an example using bandwidth queues that I used to use. They are all commented out now since I don't need them anymore, but kept them around just in case. This configuration restricted the bandwidth for web and mail. If I remember correctly, I built this from "The Book of PF" which I believe is available on the web now.
############ Queueing: rule-based bandwidth control.
#altq on $ext_if cbq bandwidth 100% queue {normal, web, mail}
# queue normal bandwidth 99% qlimit 100 cbq(default)
# queue web bandwidth 100Kb qlimit 100 cbq
# queue mail bandwidth 250Kb qlimit 100 cbq
############ Filtering: Last Rule Matches #pass log proto tcp from any to any port 80 queue web #pass log proto tcp from any to any port 25 queue mail

My SysOps engineers are stuck in getting it done, so I`m looking forward to get a resolution or any consults onboarded.
