        @stephenw10 when removing queue from Limiters

        Also this bug is annoying

        there were error(s) loading the rules: pfctl: opvnc1: driver does not support altq.
        I have opvnc2, opvnc3 no any warning and this bug for opvnc1

          You have added a ALTQ queue on that interface?

          What the exact steps required to replicate this Limiters issue?

            @stephenw10 No, after this crash I removed Limiters and going over traffic shaping wizard. Did set OpenVPN clients as separate interfaces WAN and got this altq bug now.

              I told, with Limiters active (Floating rule as well active on WAN) I removed 2 queues from settings. Before get set 3queues on each Limiters and during removing 2 of them was crashed!

                Were you routing traffic through those queues or through the parent limiter? I can't replicate that here.

                      So rules were set to use the parent limiter not any of the queues you removed directly?

                        @stephenw10 If you mean floating rule, I did ll the same as described in pfsense docs with a setting against bufferbloat, only add more 2 queues during set up on the same parent Limiters and removed later 2 of them and remain one queue only

                          Ah, OK so now we're getting somewhere. You had the Limiters setup for codelq.
