      @stephenw10 isn't there a whole other thread going on for quite some time about vlan 0? I have just stayed out of that one - no experience ever using a vlan 0.

      But vlan 1 should pretty much never be tagged. That is just the default vlan ID uses use for their default untagged default network.

      But yeah that double tag thing doesn't look right to me.

      edit: Just me and my ocd I think - but why would you tag 192.168.10 with an ID of 20 and 192.168.20 with 30?, wouldn't 10 be better ;) just so you know hey 192.168.10 - that is vlan 10, I do that with my vlan 4 and 6, they are 192.168.4 and 192.168.6 networks ;)

        You can, sure, my native VLAN is untagged with vlan 1 on the switch. It worked before so I did not bother.

          Watched Tom Lawrence once, and he tagged them that way :) If it matters I can rename them, if you think it matters

          VLAN 1 is not tagged in my case. It's only in the switch. All the ports on Group VLAN 1 are untagged.

            no doesn't matter - just odd, it is common practice to use an ID that somehow relates to the IP range is all.. But the vlan ID has zero to do with the IP space used on the vlan..

              @johnpoz I will rename them, I know it's not logic to follow when debugging.
              On your primary switch what do you have for native 1 or 0 ?

                Can we see the other VLAN config tabs? What is that switch? What firmware version?

                But I would still get a laptop on to it and take some pcaps there to see what's happening.

                  My default is 9 ;) common practice to move away from 1 in the enterprise. Have never seen 0 to be honest.. Its more of a special use ID, have never ever seen 0 used on a switch as the default vlan. Every switch that I can remember has always been 1 as the default vlan.

                  switch.jpg

                  Notice - doesn't allow you to set 0, its 1-4094

                      @nrgia why do you not have any untagged ports in your 10 or 20 vlans? Do you have no devices actually plugged into this switch on those vlans, and only other switches or AP?

                        The QoS and PVID tabs?

                          So it's like this
                          On port 5 it is connected a Unifi AP - VLAN aware
                          On port 15 is pfsense (LAN side)

                            The more I look into this the more it looks like an incorrect QoS setting being applied.

                                Hmm, well you wouldn't expect it to be doing anything with those settings but try setting QoS to 802.1p mode with no port selected and see if that changes anything in pcaps.

                                It pretty much has to be the switch doing that since it's just passing the tagged traffic.

                                  I will do as you say, but I remind you that with pfsense 22.01 worked, I did not touch the switches.

                                  So, first change the setting and then to do a dump from where? pfsense or hook up a laptop to vlan2.20 port ?

                                    I'd repeat the previous dump where we could see the double tagged traffic arriving from the the device at .56.

                                    I'm suggesting that this was working in 22.01 at earlier because the driver was incorrectly stripping the tags and now after the fix it is not. FreeBSD now drops the traffic because that's what it's supposed top do with VLAN0.
                                    The last snapshot that worked was built just before that fix was added. On the same day.

                                        @stephenw10 said in pfSense 22.05 breaks VLANS, restoring pfSense 22.01 fixes the issue:

                                        I'm suggesting that this was working in 22.01 at earlier because the driver was incorrectly stripping the tags and now after the fix it is not. FreeBSD now drops the traffic because that's what it's supposed top do with VLAN0.
                                        The last snapshot that worked was built just before that fix was added. On the same day.

                                        At least I'm not crazy. :)

                                          Ok, no difference.

                                          Ok let's try to verify it is the switch doing this. Can you connect one of the access points to ix2 directly?
                                          Otherwise lets get a laptop on one of the ports and see what's arriving at the other end.

                                          It looks very likely to be the switch. There's probably some combination of QoS settings that will allow it to work. Enabling it on an unused port. Enabling it on the ports we need (pfSense doesn't care about the priority tag).

                                            Yes I can, and I can validate by having Internet on My phone.
                                            For example both WLANS are having the same tags as our VLANS.
