        If it's not enough, tell me what to "grep" for, I dumped it to a file, due to too much lines.

          Hmm, so still only outgoing packets. At least as far as tcpdump can see.

          Are you able to pcap on something upstream to see the tagged traffic that should be arriving there?

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

              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."

                  @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?

                                    172.18.0.0 is the native LAN

                                    the dump is on ix2

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

                                      netgraph

                                      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)?
