      If you copy the file to /conf it will be used in preference to the system generated file.

      Also check other config options: https://mpd.sourceforge.net/doc5/mpd.html

        @stephenw10 ok so I should copy mpd_wan.conf to /conf and edit it there leaving only the line that needs to be overridden in the file correct? just making sure because I tried a couple of things but nothing is enforcing the edit we want. Thank you for all your help Steve.

          Nope it uses the complete conf file from there so it has to contain everything it did in /var/etc

              @stephenw10 copied the whole config file and edited it and it is overriding correctly but it's still retrying every 9 seconds after timing out. Might this line be useless for this? if so, what can I edit in it that could override this?

              I think this should be available in the GUI as other people might have the same issue too, there are a lot of slow and stupid ISPs.

                  Yeah, the keep-alive setting probably isn't what you want there, I expect that to apply once the link is up:

                  This command enables the sending of LCP echo packets on the link. The first echo packet is sent after seconds seconds of quiet time (i.e., no frames received from the peer on that link). After seconds more seconds, another echo request is sent. If after max seconds of doing this no echo reply has been received yet, the link is brought down.

                    @stephenw10 what can I do then? there is no way to get PPPoE to work on pfsense then?

                      Well there may be other mpd options there that would help here. I've never tried because I've never seen a PPPoE link that took that long responding.

                        @stephenw10 do you know any other mpd options that might help? it's literally a 3-second difference

                          @aelakkad it connects fine on windows and on the router itself so why does pfsense force 9 seconds when it could be more than that?

                            Without seeing the actual pcap data it's hard to see exactly what the timing is. It look to me like pfSense is sending requests with increasing delays; 2s then 4 s etc. The server sends a response after ~4s nd that restarts pfSense's sequence. So pfSense could be rejecting the response, without logging that for some reason. That could be because it's a response to the first request not the current one.

                            Try adding: set debug X where X is 0 by default but can be higher.

                              @stephenw10 do I add it in the /conf/mpd_wan.conf file or in the tcpdump commad?

                                Im trying to highlight them below, they look very consistent and keeps going like that the difference is almost exactly 10 seconds

                                  The debug line would be in the mpd_wan.conf file.

                                  Ok, so we can see the unique id of the request is sent 3 times then the server replies. But it could be replying to any of those three requests.

                                  The fact that the reply triggers pfSense to start with a new request though seems indicate it's refusing the offer.

                                    @stephenw10 what would make it refuse the offer? I set debug 10 and did another pcap

                                    packetcapture-igb0-20230922022327.pcap

                                    is there a way to stop it from rejecting the PADO?

                                      I'm still not 100% sure it is actually seeing the replies. It could be that it only ever tries the same ID 3 times whether or not it sees a reply for example.

                                      With the debugging logs do you see 3 sent messages for each 1 received message?

                                      This really seems like the solution is going to be something simple like it needs an identifier set. But I assume you didn't set anything like that in the Windows client?

                                        @stephenw10 how can I export a better debug log, I've set it to 10, should I set it to more for example? And is there a way to download/export the system log from the GUI so it could be more helpful to us?

                                        Is there some way to implement the identifier set? I did not set one in windows, only username and pass, nothing else at all.

                                          We're off the map at this point. 😉
                                          I've never had to set debug logging to get PPPoE connected so I can't tell you. Try it and see. You can download the full system log file from /var/log/system.log

                                          You can set a service name in the PPPoE client. It's almost never required though.

                                            @stephenw10 yea I asked the ISP and no service name required. I just don't understand why pfsense wouldn't just wait a couple of seconds, the router and pc do wait. Like it's literally a couple of seconds and we cant override it and it's rendering the whole this useless it's very frustrating.
