      I was testing the WAN redundancy when I noticed that the PPPoE connection I have is not coming back up once I disconnect and re-connect the cable.

      Re-saving the interface config does not fix the problem. Manually killing mpd5 and re-saving the interface config does not fix the issue. The only way that the PPPoE is re-established is if I reboot the box.

      The PPP logs contain this:

      <edit>I have found this same issue mentioned in this bug report:
      http://redmine.pfsense.org/issues/1943

      It mentions a work-around. Could this work-around be implemented in all future releases?

      <edit #2="">The work-around seems to fix this issue. What other potential problems might arise from implementing this work-around?</edit></edit>

          That thread seems to be about a different issue, because for me it was enough to implement jimp's solution from this thread:

            that workaround works partially, meaning if there is link loss only which is when u pull the plug, if the link is up and pppoe disconnects then its a reconnect loop and this happens if the isp modem is reset or if that reboots which is more likely to happen and others have a switch between pfsense and the isp modem in which case link loss is less likely to occur at all

              As long as it works for one use case I see no reason for not implementing this fix. It may not fix all possible situations, but it fixes some.

              For me this fix works because I have no provider modem in my home - I just get a Cat5E cable that I plug in my pfSense box. There is a provider box in the building and they have some kind of Huawei CPE there that does internet + voice + cable TV over a single fiber pair. My Cat5E cable plugs into that device.

                yes its true it fixes partially in link loss situations and should be implemented.

                i guess u have FTTB and i have FTTH so ur modem is in the building and mine is at my home

                  Could this fix be implemented? It's only the matter of removing one line.

                    I have no problem with reconnection, since 2.1 beta0 builds, even if this line presents.
                    May be there are some problems in other configurations if this line is removed, but I am not sure.

                    On 2.0.x builds I must to down/up physical interface (if config down em0…) to reconnect after link loss and removing that line does not work for me also.

                      I find Dynamic DNS clients can't re-connect link after for auto update.  please check and fix it.

                      :P

                        Bumping this thread.

                        Could this simple fix be implemented?

                        @jimp:

                        Failing that, give this a try: Edit usr/local/sbin/ppp-linkdown and comment out or remove this line (keep an unaltered copy around though so you can restore the copy if it doesn't help)

                        /usr/sbin/ngctl shutdown $1:
