      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.

          I did like you suggested:
          pfSense->Unifi AP->Mobile Device
          The only SSID that gets internet is the one without VLANS same with the switch.

          So it's not the switch. I excluded all the switches.

            Ok, did you get a pcap from it?

            You might have to run it without 'vlan' in case traffic is arriving untagged entirely.

              Another test you could do would be to add a port on the switch as untagged in VLAN 20 with the pvid set to 20 and connect a host to it. Does it pull a lease from VLAN 20.

                No I was connected only on my mobile device, but I can do the following:

                1. Connect with a laptop via Wi-fi
                2. Or directly to pfsense via cable

                How do you prefer?

                  A pcap on ix2 in pfSense as before would show if it's still seeing the off double tagged traffic arrive. If it is that implies the AP is tagging it and the switch is just passing that.

                  Testing the switch without the AP would also confirm that.

                    @stephenw10 Yes but I want the same port to have both 20 and 30. Can I do that as you instructed? I mean let's take an AP, you will have multiple SSIDs but connected to different VLANs

                      The tests done previously were done via wire, not wireless, the last test was done after you suggested to change the QOS setting.

                      I'm not sure I follow what you suggest to do now.

                        Suggestion

                        Do you know how to make a "Monitor/Span Port" on the Switch ?
                        If yes ... You said you had a Manjaro Linux where you could run WireShark.

                        Make a Monitor port on the switch , that monitors the port connected to pfSense , both RX & TX.

                        Connect wireshark to the Monitor port , and make a packet trace that way.

                          If you can make one VLAN work 100 will also work, that's not the issue.

                          There are two tests you can do.

                          Connect one of the APs directly to ix2. Run a pcap in pfSense on ix2 as you did before. Try to connect to the SSID using the VLAN and see what appears.
                          If you see nothing try running it without the 'vlan' option in case the traffic is arriving untagged.

                          With the switch comnected to ix2 add a port as untagged in VLAN 20 with the pvid set to 20 and connect a host to it. Does it pull a lease from VLAN 20.
                          If not run a pcap in pfSense again to see what's happening.
                          You can also pcap on the wired host to see what that sees.

                            I think you are referring to port mirroring, too many wires. But good idea :)

                                This test is like this:

                                1. Connect AP directly to pfsense LAN port
                                2. Connect a laptop wireless to Native LAN(via non tagged SSID) in order to access pfSense
                                3. Start tcpdump on ix2
                                4. Try to connect a mobile phone to VLAN 20 SSID
                                tcpdump -e -i ix2 vlan

                                  Ok, interesting. No outbound traffic there but there's no reason that should be any different.
                                  We still see all the VLAN0 tagged traffic arriving which implies the APs are tagging it.

                                  I would bet if you run the second test with only the switch it will work fine.

                                  What sort of QoS settings do you have on the APs?

                                    In a moment, I had to do some tricks for the tests :). Don't worry I cooperate :) Thank you for staying this long with me.

                                      Ok, interesting. No outbound traffic there but there's no reason that should be any different.
                                      We still see all the VLAN0 tagged traffic arriving which implies the APs are tagging it.

                                      I would bet if you run the second test with only the switch it will work fine.

                                      I don't think Ubiquity does that on AP. AFAIK you must purchase a router or a switch to achieve that, but I can look in the Unifi Network Controller .
                                      I don't see nothing that I can turn on the AP regarding QoS.

                                        Last test as you instructed:

                                        1. Added port 7 to VLAN 20 group and marked the port Untagged
                                        2. Set PVID 20 to port 7
                                        3. Started tcpdump on pfsense for ix2
                                        4. Connected the cable to a desktop and to port 7

                                        The desktop MAC is b4:2e:99:c7:b4:26

                                        tcpdump.txt - sorry was too big

                                        No lease, no internet

                                        Maybe I should've removed port 7 from VLAN1 group also?

                                          Hmm, well that's weird!

                                          As long as you changed the PVID on port 7 to 20 then it would only be one way traffic anyway. I shouldn't prevent traffic VLAN20 working.

                                          Were you able to take a pcap on the connected desktop?

                                          It's hard to imagine what could be tagging that. It seems very unlikely the AP and switch would be doing so independently.

                                            I thought you're off for today :)

                                            I started to revert back to 22.01, in order to get things running again.

                                            If you need pictures with the switch I can provide. I don't have any reason not to follow your suggestions. I'm the first who wants to solve this.

                                            I tried to dump the desktop, but the interface was not getting any ip just a local one with 169...something...so I provided the ix2 one, dumped from pfsense.

                                            I can reinstall 22.05 tomorrow if you are still willing, and still have ideas :)
