      @stephenw10 I tried the default and set up my own check service, and of course both are reporting the correct IP address. I am using a custom DDNS service (ipv64.net). I had no problems with it with 2.7.x. So that's why I think it's a problem with the 2.8 release.

            Hello,

            can you try to add as check service: http://checkip.dns.he.net ? or: https://checkip.amazonaws.com/ ?

              Try running in Diag > Command Prompt:

              Screenshot from 2025-06-03 13-05-23.png

              It should return the correct public IP as a string.

              Is everyone hitting this using pppoe by chance?

                    OHhh - so there must be, in your case, a other cause for not getting the pppoe0 adress ... 🤔
                    I have here also dyndns with pppoe but not with cloudflare as provider ...🤔

                      I have pppoe here too but not cloudflare dyndns - i guess its something specific to cloudflare ... 🤔

                          Hmm, the error it's showing should be independent of the service in use. It tries to read the IP, checks its a valid IP address and fails that check.

                          I'm wondering if it's passing the wrong interface type after the pppoe changes hence asking if anyone is hitting it on a non-pppoe wan?

                          Also is anyone using using not the actual 'wan'? Like opt1, opt2 etc?

                            @stephenw10 Just to clarify: I am still using the old module, not the new if_pppoe kernel module for PPPoE client

                              Ok. It may still be the issue though as the pppoe code was changed to allow both connection types.

                                @stephenw10 Just configured another DynDNS Service and switched to the new if_pppoe kernel module. The problem is still there

                                  Only after switching to if_pppoe?

                                  Which interface are you using pppoe on? The actual 'wan' interface?

                                    @stephenw10 before and after switching. Just wanted to confirm that the new if_pppoe module is not the culprit.
                                    I am using the 'wan' interface

                                      Hello.
                                      I am experiencing the same faulty behavior.
                                      When debugging the PHP-Command in pfSense, it returns an IPv6 in my case.

                                          Yes.
                                          Still quite common in Germany. (V)DSL so it's based on pppoe.

                                          Dynamic DNS updates stopped working just as 2.8.0 was installed. Quite a bummer for me because I am heavily depended on that function.
                                          I also tested it with the old pppoe driver and the new one - same behavior, despite I am not using cloudflare.

                                            Do you only have an IPv6 address there?

                                            I'm using PPPoE over VDSL here and it work fine. There must be something else in play.
