    Hehe now you nailed it :)
    It works perfect with one exception which I dont know if its related…

    Tried 10 times.
    6 times all ok but in 4 times I got no IPv6 address on my pppoe iface.
    Everything works as expected exept gateway monitoring (it shows status pending because ipv6 address is missing on ppoe).

    I don`t know why it happens it seems really random.

    Thanks!

      Ha! Managed to replicate when pppoe does not obtain ipv6 address…

      So if link flaps for 10 seconds or just modem reboots there is no problem.

      But when link is down more than that and LCP echo requests start to fail or pppoe reconnect after 5th LCP missing is exectuted, then pppoe does NOT obtain IPv6 address and gateway is marked as pending.
      IPv6 from firewall and subnets is working just fine, again just gateway monitoring is impacted...

      BR,
      Greg

        That's good news. My bad for not thouroughly checking for any other posix_Kill() calls for dhcp6c so sorry for that.

        I have noticed that sometimes the gateway monitor does not reflect the real state after an up/down event. I tend to no believe it if I can see the addresses are all there and just leave it, the page refresh always seems to sort it out after a while.

        I'll merge those commits into one later today and update the PR.

          @marjohn56:

          The patches are:

          718cbc2d3921627e9767e59d539386c843dffcc4
          ea4de27b15441763bd227a2a942df522d98775c8

          e660bd4f34245958a290240c04afacb0823d4b74

          At the risk of looking dense - what patches where? Is there some PR for this?

              :D

              Note that if you apply the lot you'll get REASONS working too, you should see some effects from dhcp6 renews no longer triggering wan updates, makes the logs much quieter.

                I did not mean to be sarcastic, I wanted to make sure that there's a proper PR for this, otherwise you end up with half of the patches getting lost and things broken

                  J/K :)

                  About my IPv6 on pppoe iface issue, should I start new thread/redmine or is it somehow connected to this?

                    It's ALL related in there somewhere, but gateway monitoring is not an area of pfsense I'm familiar with, so whether its related to locks and reasons, i'm summing the two, or something else thats always been there I have no idea… at the moment.

                      I'll snapshot my test system and do the patches, then I'll throw some curved balls at it and see if I can replicate the monitoring issue. On a side note, I'm changing ISP in a couple of weeks and my v6 will no longer be dhcp6 without RA ( that's a mismomer and we should change it! ) but similar to Mav*Slo, so I will be able to see exactly what's going on there.

                        No no, gateway monitoring is just consequence…

                        Look what I mean:

                        When things are 100% OK:

                        And when there is no IPv6 on PPPoe:

                        
                        Status

                          Can you do a test for me, go to the shell, and firstly check that dhcp6c is running, if it is, then can you send it a SIGHUP, SIGHUP being  'kill -1 PID', see if that makes it recover.

                            DHCP6c IS running.

                            No change on pppoe :(

                                What do the dhcp logs show at that moment?

                                    So it appears dhcp6c is working, and by the look of it so is RTSOLD. Hmm, pppoe thing. Not even sure if it's related or not.

                                    Try this, see if it makes any difference. Just add it on the end of the others.
