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

      and

        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.

                  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.

                          @bigsy Does applying this patch help?

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