      I appreciate your time guys.

      This is the board if it helps
      https://www.supermicro.com/en/products/motherboard/A2SDi-4C-HLN4F

      Should I provide a TCP dump on vlan interface or on the native interface ?
      I mean in my case ix2 or ix.20 ? Or both ?
      Thank you

        Look on the VLAN. If there's nothing there look on the parent for the tagged traffic. Or just do both anyway!

        If you're doing that in the pfSense GUI be aware that you cannot (currently) apply filters when looking for tagged traffic. https://redmine.pfsense.org/issues/13094

          @stephenw10 I will use your cli command

          tcpdump -i

          I see it spits a lot of info, I will try to paste relevant info like in your example.

              @nrgia make sure you add -e on tcpdump or it won't spit out vlan tag info

              but isn't that 192.168.10 your vlan 20?

                Yeah, so that looks expected for a dump inside the VLAN. Except there's only outbound traffic.

                So run tcpdump -e -i ix2.20 and see if the tagged traffic is arriving.

                  Yes 192.168.10.1 is vlan 20

                  Here you go:

                        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

                              @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."

                                  @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.
