      @stephenw10 Here's the updated logs. For safety, I've replaced the WAN IP with $_WAN_PUBLIC_IP_$ and my ISP's gateway with $_ISP_GATEWAY_$.

      Log #1 - Connection works after system restart

      Log #2 - Fails to reconnect if the connection dropped for any reason

      This line keeps appearing:

      IFACE: Adding IPv4 address to pppoe2 failed(IGNORING for now. This should be only for PPPoE friendly!): File exists

      Thanks!

        Hello, did you find out what was the problem ? Because I have the exact same problem with the exact same errors after upgrading to 2.4.4 .

        [opt1] IFACE: Adding IPv4 address to pppoe0 failed(IGNORING for now. This should be only for PPPoE friendly!): File exists 

        [opt1] IFACE: Removing IPv4 address from pppoe0 failed(IGNORING for now. This should be only for PPPoE friendly!): Can't assign requested address

        Tried everything, nothing helps. The connection works on VyOS and directly on the PC.

          @joxxxx I have yet to find a solution. For me, the (re)connection works fine on other OSes and devices as well.

          Let me know you find out anything. Unfortunately I'm considering migrating to something else.

            @vegbrasil After countless hours, I found out that the pppoe layer of pfsense 2.4.4 is bugged ! Something changed and because of that, the connection cannot be made with the above errors. Tried it also on a clean 2.4.4 install.

            Re-installed 2.4.3 and all works again without any problems ! The thing is that I cannot install any packages anymore because it wants me to update to 2.4.4...

            Btw, tried the dev 2.4.5 version and the bug is still the same.

            I hope this will be fixed because it mus affect a lot of people...

              Hmm, there must be something different about your connection. I have two WANs here, both are PPPoE. The only issue I saw was when the ISP(s) had an outage. However the logs showed it as very broken, nothing like what you're seeing.
              If PPPoE was broken in general there would be hundreds of posts about it by now.

              Are you able to try a different NIC type?

                @stephenw10 I've been using pfSense with the same FTTH PPPoE connection and two different NICs models:

                • Realtek NICs (re): crazy bugs, completely unusable - expected, I guess;
                • Intel PRO/1000 NICs (em): Problem of the initial post: first connection is fine, re-connection never happens. If we forget this problem, everything is working great and I can max-out the connection (150 Mbps).

                Upgraded and tried clean install between 2.3.5 and all 2.4.x versions.

                Thanks!

                  Hmm, yes, this seems like it must be some other issue since you were seeing it in 2.4.3 also.

                    I'm using a quad ethernet intel pro and never got any problems since v 2.0 or something like that on vmware and the vmx3 driver.

                    After analysing a bit the problem, could it be that I have this problem because pfsense sees his local ip address as the FTTH gateway ?
                    Maybe something changed in pf 2.4.4 in the pppoe connection that forbids the use of it ? (This could explain the two errors I get).

                      I'm using the exactly same hardware and since we're having the same problem, we may have found the initial cause.

                        @stephenw10 On my side, 2.4.3 is working perfectly and reaching the 1Gbits of the fiber connection. The problem is 2.4.4 and above where it doesn't want to allocate the ip address it gets (I can see the received ip address in the logs, but the error prevents it to be used).

                          How did you get anywhere with this problem?

                          I'm experiencing the same issue:

                          Could it be the PPPoE is not receiving a gateway address and the IP address its been given is a /32 255.255.255.255 address

                          This is the case with mine.

                          I started on 2.4.3 upgraded to 2.4.4 (this causes the WAN to drop and it attempt another connection - 2.4.3 got this error and left the link up)

                          Feb 4 12:22:20 ppp [wan] IFACE: Adding IPv4 address to pppoe0 failed(IGNORING for now. This should be only for PPPoE friendly!): Destination address required

                            @timboau-0 I still have the issue, running the latest stable version of pfSense.

                            This weekend I needed to visit a site that was offline due this reconnection problem. I'm thinking of making some sort of simple script to reboot the server if the WAN is offline for a few minutes...

                            Thanks!

                                  /32 is valid for a PPP connection as is a gateway outside the subnet.

                                  Obviously no gateway at all isn't though.

                                    I got my config working on 2.4.3 (but I think it will break on 2.4.4) - I had a slightly different problem to the above.

                                    With 2.4.3 I can authenticate and the interface stays up
                                    2.4.4 I authenticate and the interface cant be configured as it doesnt have a gateway IP so it goes down and then re-connects. (repeat)

                                    I fixed my problem : (Not being supplied a gateway via PPPoE)
                                    Configuring the interface with PPPoE (as per usual)
                                    Then creating a NEW interface on the same port as STATIC (save)
                                    Then open the interface again and create a gateway using that same IP

                                    I can see that if I lost authentication now on 2.4.3 I would likely loose connectivity as the PPPoE wont try again (without a reboot or port cycle)
                                    I worry on 2.4.4 that it will fail the interface configuration due to the missing gateway then the 2nd interface wont work either..

                                        Did someone noticed the same File Exists! error for PPPoE on 2.5.2 ? I have the same issue after the upgrade.

                                            Which problem exactly are you seeing? PPPoE connection with no gateway? Can we see some logs?
