      @stephenw10 ok but this means it can actually reach the modem right? so what could be wrong?

        @stephenw10 it is sending PADI and receiving PADO shouldn't it then send PADR to accept the connection and work? Any help is appreciated

          can I somehow increase the time before it times out and retries? as it seems like it might not be seeing the PADO packet and just keeps retrying again and again while it actually does receive the PADO after a while, but never sends a PADR

            Ah sorry missed your second post. Try either turning up the view mode to show more detail or download the pcap and open in wireshark. The replies from the PPPoE server might be telling you what's happening.

              I tried exporting it into wireshark and looks very consistently trying but does get anything 😞

                Check the Ethernet properties on the replies. Is it tagged in some way?

                  I dont see any tags as far as I know, it's driving me crazy not knowing why it doesn't send back a PADR back after PADO

                  This is from the PADO coming back

                    @stephenw10 is there any way to override the timeout for waiting for PADO? It seems to timeout every 9 seconds and resend the PADI again & again and the PADO literally arrives 10-11 seconds after the first PADI 🤦🏻‍♂️ 🤦🏻‍♂️

                      Hmm, that timing seems very odd. I'd expect the server to respond far quicker than that.

                      There's no config option for that in the gui but you probably can set that via an mpd config option directly. Look in: /var/etc/mpd_wan.conf

                      If you can find an option that works you can create a custom file for that in /conf.

                        @stephenw10 said in Getting private/local IP on WAN:

                        /var/etc/mpd_wan.conf

                        Yea, I guess my ISP is too slow with its response (kinda expected).

                        I found a line in the /var/etc/mpd_wan.conf "set link keep-alive 10 60" it's under "create link static wan_link0 pppoe" I think this is the link we're looking for? should edit it to like "30 60"?

                        should I edit this one? Or there is something I should do to create a new file that overrides this?

                          I tried editing it directly and rebooting so it takes effect but it reverts back to it's default. Any idea how I can workaround this, please? almost there😁

                          (tried without reboot and just disconnecting and reconnecting WAN interface in status page but same result)

                            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.
