        @jarhead I wonder if frontier is making changes so their fiber offerings are compatible to all third party products.

          Hmm, that's weird. Were you able to confirm they are actually using VLAN0 there?

            Yes. Plus, if they weren't, my router would have worked also.

              Yeah, it would just be easy to think you are hitting that because you expect to.
              I know of no reason why two nearly identical devices would behave differently.
              Different NIC firmware maybe?

                Hi Stephen, can you verify 22.11 that is scheduled for November of this year will be using freebsd 14 or main (as it is)?
                Thanks

                  That is certainly the intention. You can never be 100% sure but I'd be very surprised if it wasn't at this point.

                    I loaded dev snapshot this morning onto my back-up router em0 and wasn't able to connect on VLAN0. I don't have a way to test igb0 without taking my main router down.

                      @c45p32 I will be using my test pc this afternoon and it has the em0 driver also. I'll let you know my results also.

                        In my testing here neither igb or em appear to pass vlan0 tagged traffic. It doesn't appear in a pcap.
                        But other drivers do and pfSense will accept and respond to that without netgraph.

                        So as I understand it the script does work in Opnsense / FreeBSD 13.1?
                        Can someone confirm that?

                        If so it's either a regression in 14 or they have patched it themselves. Or they are using the kmod non-iflib driver.

                          @stephenw10 Opnsense works with em and vlan0.

                            @jarhead Hasn't Opnsense not had this problem at all (natively working with VLAN0)?

                              @schwiing Just since moving to FreeBSD 13. Had the same issue before 13 though, ie not accepting vlan0.

                                @jarhead Sounds right. I'd assume then with PFsense going to FreeBSD 14, this should be solved...maybe i wont need a switch between the ONT and Router.

                                  You would think but it doesn't appear to be the case so there must be more involved here.

                                    Correct.

                                      Hmm, looks like they are using identical drivers.

                                      Did you test with em or igb specifically? Though they are the same driver.... except if they're not!

                                        @stephenw10 would anyone be able to test with ix?

                                          It works with ix with the netgraph script in 2.6 and I expect it to work with ix without a script in 2.7 because main has the vlan0 dhclient patch.

                                          It's worth trying that on em/igb too since I can't see any different there. Though I can't see how it could work given it doesn't even appear in a pcap. I could be missing something....

                                            I loaded opnsense onto that same backup router and I can’t get it to work on em0. I even went into the attic, got the ISP router to formally release the IP and still no go. So not sure how people are getting it to work on opnsense. I’m on Frontier fiber College Station, Texas.
