      I'm familiar with Wireshark but have only run it once and that was a long time ago. I may need some help to figure that one out.

      I'm sure there's some good guides on the web though. Can report back once I figure it out

        Stephens idea is better to use pfsense built-in packet capture.

            I always enable promiscuous mode to be sure but that shouldn't be required here. I won't hurt either.

              @stephenw10 Ok. I ran a packet capture and renewed WAN + relinquished my lease. Didn't get an IP back so I had to reboot the ONT, after which I got an IP back. Stopped the capture and got a .cap file. Here's what it says (masked my IP):

              07:44:40.852150 IP 0.0.0.0.68 > 255.255.255.255.67: UDP, length 300

              07:45:03.113370 IP 0.0.0.0.68 > 255.255.255.255.67: UDP, length 300
              07:45:03.131465 IP xx.xx.xx.1.67 > xx.xx.xx.xx.68: UDP, length 300

              07:45:07.731435 IP xx.xx.xx.1.67 > xx.xx.xx.xx.68: UDP, length 300

              Did I do it right? Can't really tell.

                Yes, now change the detail level to full and hit 'view capture'. Scroll down to the replies and see if there are any tags.

                  @stephenw10 Ah, i didn't set it to full before - good catch.

                  Apologies for the dumb question but, what does the tag look like? What term should I search for?

                      @stephenw10 I don't see the term "vlan" anywhere in that packet capture. My guess (if I did it correctly) is that it's not tagged.

                        Yeah, I'd be amazed if it was and still worked in 22.05. Good to check though. 👍

                                @stephenw10 Steve, do you need me to check something? I am one of those stuck under 22.5 and working, everything else did not work as you can see in all my other posts. :-)

                                  I can confirm as of this morning, College Station, TX still wants vlan0.

                                  11:34:03.435271 00:00:00:00:00:00 > 00:00:00:00:00:00, ethertype 802.1Q (0x8100), length 60: vlan 0, p 0, ethertype IPv4, (tos 0x0, ttl 246, id 54321, offset 0, flags [none], proto TCP (6), length 40)
                                  xxx.xxx.xxx.72.50650 > xx.xxx.xxx.xxx.3050: Flags [S], cksum 0x8ea1 (correct), seq 1903919664, win 65535, length 0

                                    You are seeing it pull a lease in 22.05?

                                    If not it won't work there with VLAN0 without the netgraph script. You'll need to go to 2.7 or wait for 22.11 snaps (which should be any time now).

                                    Steve

                                        The updates look like their coming pretty fast. I'm surprised 22.11 dev isn't available yet
