      @bigsy if_pppoe shouldn't have any impact on the WebGUI access.

      If you upgrade to 25.03-BETA and not enable if_pppoe, does all work as before?

          @bigsy that's a new one then.

          Can you still access pfSense using SSH/console and restart the WebGui (menu entry 11) and or restart php-fm (menu entry 16)?

            @patient0 Thanks for the replies. I've been switching between boot environments to test things.

            I have both console and SSH access. Menu options 11/16 didn't help.

            I then realised that there was no DNS resolution at the CLI, so I manually restarted unbound and then menu option 16 brought the webgui back up.

            It appears to be working now. I'll keep it running to see if there are any more problems.

              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 ??

                  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.

                                      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.
