      Can you give me an example, please.
      I don't have Wireshark installed.
      I found it, it's in the UI, Packet capture

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

        length 68: vlan 0, p 0, ethertype 802.1Q, vlan 20

        That seems odd.. why is showing vlan 0 and vlan 20?

        What is this guy 28:6d:97:7f:bb:0c, is that pfsense

        That isn't outbound from pfsense.. Your other post shows ix2 as ether ac:1f:6b:45:fa:8a

        A mac vendor lookup shows it as SAMJIN Co., Ltd.? Never heard of that company.
        Seems "The Company provides its products mainly to Samsung Electronics."

          Mmm, that is a very good point! Like it's QinQ.

            @johnpoz If you must know 28:6d:97:7f:bb:0c is a Samsung Smarthings v3 Hub which is on vlan 20 :) It screams for Internet connection, but it doesn't get it :)

              @nrgia but showing vlan 0 with a p0? But that is inbound to pfsense.. I don't have a lot of experience with setting priority on vlan 0, etc. But that could be maybe why pfsense not actually seeing the tag 20?

                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?

                                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)?

                                        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.

                                        Ok did what you asked:

                                        pinged another 192.168.10.58

                                         tcpdump -e -i ix2 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....
