      I then realised that there was no DNS resolution at the CLI,

      Check the resolver log ( and system log ) if you can find a reason why the resolver didn't start.
      /var/log/resolver.log and /var/log/system.log.

      No "help me" PM's please. Use the forum, the community will thank you.
      Edit : and where are the logs ??

        @Gertjan system.log during boot up has a lot of messages along the lines of:

          Looks like it's looping. Do you have Do not wait for a RA set in the dhcpv6 settings?

          Try unchecking that. If that allows it to connect normally that's a known issue that should be fixed in the next public build.

            @stephenw10 Thanks. 'Do not wait for a RA' is NOT checked in the DHCP6 client configuration.

              Hmm, interesting. Do you see the connection logs repeating? Like it's continually re-connecting?

                No, the connection seems to establish and stay up.

                  Hmm, but the logs are still filling continually?

                    Sorry, but I'd like to correct you that "Do not wait for RA" should be checked to bypass this issue.

                      It depends which issue. If your ISP sends a lot of RAs you probably want it checked. If not then leaving it unchecked can avoid a race condition.

                      Both should be fixed in the next build.

                        No. The logs fill with those messages on rebooting after enabling if_pppoe and also on each subsequent reboot.

                        This stops once I restart unbound via the cli and then use menu options 11/16 in order to be able to access the webgui. Once that is done the continuous log messages stop.

                              Thanks. Afraid it didn't help - I applied the patch, rebooted and the same behaviour was exhibited.

                                I'm still experiencing the same problems as originally described on the latest 25.03-BETA (amd64)
                                built on Thu May 15 15:15:00 BST 2025                                 whenever if_pppoe is enabled and the system rebooted.
                                No problems when if_pppoe is not used.

                                  Hmm, do you have a more complete log of what you're seeing?

                                  If you set 'Do not wait for RA' does the behaviour change?

                                    @stephenw10 i can provide logs if you want to look at them. I previously tried the ‘do not wait for RA’ option and there was no PPPoE connection.
