        Yes, I can confirm that IPv6 works good. About 36 hours and no problem.

            @rschell idk if it's related to this update but lately i had trouble with my ipv6 tunnel, i still need to investigate but the problem is that my tunnel does not work after a reboot
            the gif is up but gateway monitor say packet loss 100%
            i had to reboot 2 / 3 times in a row to make it work again

              @kiokoman Unlikely related to the proposed patch. I'm using an 6RD stf interface and have noticed issues with loss of the WAN connection. Might be a timing issue with the gif interface, not certain.

                some kind of race condition at boot maybe, also if i wait some hours the tunnel start to work alone. but it's faster if i reboot until it start working. idk the problem started last week just after i moved pfsense from bare metal to esxi, probably something to do with that

                  @kiokoman I've noticed that bare metal vs Hyper V behave differently in subtle ways.

                    ok i think that i found what's going on, if i disable openvpn before restarting pfsense the tunnel work.
                    so i have to disable openvpn, restart pfsense, and when it's up i can start the openvpn otherwise i have trouble

                      Looks like there are no error messages on the latest STABLE snapshots.

                        do we no longer have to apply that patch manually?
                        I have not yet had time to update and verify

                              Waiting for https://github.com/pfsense/FreeBSD-ports/pull/773 to be merged. I have no problems with patched binary.

                                @kiokoman It appears you are still using the patched binary. I had my main pfSense running for 35+ days with the patch, so I am reasonably certain that it is a good work around for the issues in stable-12.

                                  Yep, it can be true, I have found it right after installing STABLE. I looked for a error messages, did not found it and did

                                  pkg install -f -y radvd

                                  It downgraded my version back to that one which is in the pfSense repository and sorry guys but it failed the same way as before. I just forgot that another one error message

                                  IPv6 forwarding on interface seems to be disabled, but continuing anyway

                                  got its own fix and I thought that the current version was updated so sorry guys for false hope!

                                    ah ok, then the upgrade didn't remove the patched radvd, well no problem it works, I'm happy

                                      I'm running the latest development release:

                                      2.5.0-DEVELOPMENT (amd64)
                                      built on Wed Jun 03 13:09:01 EDT 2020
                                      FreeBSD 12.1-STABLE

                                      This morning, I noticed the routing log filled with this message:

                                      Jun 7 10:01:16 radvd 76671 can't join ipv6-allrouters on hn1

                                      IPv6 was not working. I rebooted and the system is now working.

                                          I also notice many messages like "Jun 11 11:02:57 pfSense radvd[84278]: can't join ipv6-allrouters on ix1.116"

                                          However I would like to add:

                                          • after installing the 3 june package a few days ago ..... they were gone
                                          • today I installed the 10 june package and they where back
                                          • and I did have an IPV6 routing problem ...
                                          • than I did a reboot and ... the messages where gone
                                          • and my IPV6 routing issue seems to be gone

                                          Note that this is not at all an real test, just a quick obeservation.

                                          Louis

                                            The routing log was full of the messages this morning, so the problem is still present.
