      I don't know what to say, but pfSense 22.01 see it just fine.
      The native LAN is working just fine, vlan 20 and vlan 30 are dead.

        Mmm, can you generate some traffic from pfSense on VLAN 20 and run that again so we can see what outgoing packets look like?

        Though I would expect to see some there anyway....

            Try to ping something in the VLAN20 subnet and it will ARP for it.

              @nrgia trying pinging some IP from pfsense, it would for sure atleast send arps that would be tagged or should be.

              edit: haha jinx :) great minds think a like it seems ;)

                Yeah so try running: tcpdump -e -i ix2 vlan

                Then try to ping anything in the vlan 20 or 30 subnets from pfSense. You should see at least the ARP traffic and how it's tagged.

                  Are you running any version of the netgraph vlan0 tagging scripts for your WAN?

                    172.18.0.0 is the native LAN

                      I saw "netgraph"in that defect. So If I don't know what it means, I think I don't use it.

                        Ok, so we see pfSense sending traffic as expected. But no response. Presumably because that device is behind some sort of odd double tagging somehow.

                        Can you try pinging something else in that subnet?

                          @stephenw10 how do you want the dump to be, on ix2(Native) or ix2.20(VLAN)?

                                The native (parent) NIC. We need to see the tagged traffic in the pcap and capturing on the VLAN removes that.

                                Using tcpdump -e -i ix2 vlan will show only VLAN tagged traffic which will make things easier to read.

                                  Hmm, so that clarifies what we saw before. The only incoming traffic is strangely double tagged.

                                  But that does prove we can see incoming tagged traffic. Which implies nothing else is sending VLAN 20 tagged replies.

                                  Do devices at .58 and .60 actually exist? Can you check for the incoming ARP requests there?

                                  There has been some driver changes in ix including that specific fix for VLAN0 traffic but that was before 22.01 not between that and 22.05....

                                    This is what I have on DHCP leases screen:

                                    https://imgur.com/a/FOgNOyU

                                    They exist but they are offline

                                    Only IOT devices are on these VLANS, most of them are Wireless, the only one wired is 192.168.10.58 and connected to a specific port.

                                    The last pfSense that worked(besides 22.01), to have timeline, was pfSense-CE-memstick-2.7.0-DEVELOPMENT-amd64-20220314-1916. After that all snapshots behaved like it is now.

                                      @stephenw10 Can we try something else...I don't try to be smart or anything, but how do I set those 2 VLANS to have PROMISC tag? I know it works for you. But maybe we can try

                                          Yep figured it out from here https://www.freebsd.org/cgi/man.cgi?ifconfig

                                          As you said, it does not work but I had to try. Don't get my wrong, thank you both for what you did until now. I'm just desperate. :)

                                          I'm open to ideas, if you still have any.

                                          Would it be useful to compare with a dump from 22.01, to see how vlans are handled there in my case? Should I revert back for now? Or should we try something else?

                                            I would get a laptop on an access port on one of those VLANs so you can see what's happening at that end.

                                            It's possible something got fixed and that has broken your setup because the double tagged traffic is now dropped as expected.
                                            We don't see double tagged ARP replies from those devices though so it's unclear if they ever see the requests.

                                            What is handling the VLANs in between? How is it configured?
