      In the latest snapshots you have an option to use the IPv4 interface as parent for IPv6.
      You have to use the checkbox labled "Request a IPv6 prefix/information through the IPv4 connectivity link" for this.

      Then the IPv6 information is requested through the PPPoE session.
      If you ISP only provide you with a prefix and not with an interface address you have to check the box labeled "Only request a IPv6 prefix, do not request a IPv6 address" also.

      You are right, when I tick this box the correct interface is used.

      Must say though that the wording for the checkbox is bad since there is no IPv4 involved anywhere.
      It's IPV6CP on the PPP connection.

      @avink:

      This works perfectly. the configuration files are ok.
      Unfortunately the DHCPv6 client daemon is not started when you request the v6 info through the PPPoE session.

      I can confirm this issue. I also needed to manually start dhcp6c.

        That box has been checked for me all the time and no it doesn't make it work ! There's something wrong, it used to work now it doesn't, right after an upgrade, …

          They will need more information like in which snapshot it worked?
          I am also seeing the same thing here on my vdsl2 (pppoe) connection.

          Watchdog keep trying to start up radvd every mins but fails, please let me know if I could be more of help, things like other system log and so on.
          Unfortunately I can't really say which snapshot worked as I only just started using ipv6 in latest snapshots. And the only time ipv6 worked for me was months back before RC.

          meanualy start with this command worked.

            Currently I'm running the snapshot from July 25.

            Last saturday I tested the snapshot from August 31 because I saw a lot of link flaps on the system (still think this is a driver issue, but that's another thread), and it had the same issue.
            I have to start the daemon by hand.

              I think that the only issue you are seeing here is that dhcp6c is started before pppoe has been connected and fails.
              Can you confirm this is the case ?

                My log was pulled after pppoe has connected for about 12hours, in that 12hours watchdog just showing the same thing every mins.
                Unless I start it manually.

                  Upgraded to Sep  3 02:29:12 EDT image and can confirm dhcp6c is still not started on boot.
                  Don't know if it is dhcp6c is started to early. You can check from attached (anonymized) system.log pulled after boot and after manually starting dhcp6c

                  Then upgraded to Sep  3 14:08:44 EDT image and can confirm dhcp6c IS not started on boot.
                  (anonymized) system.log attached too.

                    You seem to be low on resources since php processes are getting killed all over.
                    Also can you share your configuration seems you have some strange thing in there!

                    EDIT: Can you try with todays snapshot since there were some changes done for low resource systems.

                        Try this commit https://github.com/pfsense/pfsense/commit/d6df2c4c71678b5edd98892ca40facbb80f4ed1c manually or use a tomorrow snapshot and see if this behaves better.

                          Just upgraded to the "Sep 4 01:46:07" snapshot. This snapshot and the Sept 3 14:08:44 snapshot both DID start dhcp6c correctly

                          On memory usage: both Sep 3 snapshots had 8 lines with the word "kill" in them. The Sep 4 snapshot has only 3.

                            Tried it. What should it improve? I still have 3 lines with "kill" in sysem.log and dhcp6 is started too.

                              ok now dhcp6c doesn't crash, .. however the ipv6 routes are not working

                              /usr/local/sbin/dhcp6c -f -d -D -c /var/etc/dhcp6c_wan.conf -p /var/run/dhcp6c_pppoe0.pid pppoe0

                              makes them work though, ..

                              if i do sockstat -46lp546, it shows a lot of dhcp6c clients on that port and also a php and sh script. however they keep cycling, as if they crash constantly
