      I just made a post inquiring about a not-getting-an-IPv6-on-pppoe problem before I found this thread.
      My setup is described here: https://forum.pfsense.org/index.php?topic=104895.0

      I've tried applying your patch to see if I could get ipv6 on WAN, but it doesn't appear to work for my problem.
      If there's anything I can do to help, I'd be happy to.
      Screenshot from first boot after applying the patch attached.

      I've just replied in your other thread.

      I urge you to give MTU 1500 operation a go using RFC 4638, as I described in that thread - it should work with your setup, assuming bhyve and your NIC is capable of using jumbo frames on your WAN interface.

        MTU 1500 works as advertised. But I'm not getting an IPv6 on WAN (yet)

            Steps
            revert previous patch, delete it
            update to newest built:
            2.3-BETA (amd64)
            built on Wed Jan 06 07:53:18 CST 2016
            FreeBSD 10.2-STABLE

            create newest patch (from your description), fetch it

            After fetch, test it, but…

            Apply = clean
            Reverted = not clean

            /usr/bin/patch --directory=/ -f -p2 -i /var/patches/568d8e2e969e1.patch --check --reverse --ignore-whitespace
            
            Hmm...  Looks like a unified diff to me...
            The text leading up to this was:

            done
            

            Apply patch
            reboot

            Test 1
            after reboot no IPv6 traffic
            Multiple Interface disconnect-connects, still no IPv6

            Test 2
            Same after several reboots:

            • IPv6 Link Local
            • IPv6 Address
            • Gateway IPv6

            Leaving me in a non operationel IPv6 state now.
            If you like, I can do more tests

            Edit: If I find the time, I will reinstall 2.3.b and recover the configuration to make sure the problem has nothing to do with all the updates I performed.

              After uninstalling patch, again updated to newest (2.3.b 7-jan 2:26) version of pfSense refetch, apply en reboot IPv6 is working again. Also after several reboots

              Don't have a clue why it did't work te last attempt, maybe I made an configuration mistake (It was late on the evening…)

                It's good news that things are now stable with your IPv6 connectivity.

                It would be useful if you'd try the patch again. It hasn't changed since you last tried it.

                Please also give outline details of the connection - especially the settings for "IPv4 Configuration Type", "IPv6 Configuration Type" and "Use IPv4 connectivity as parent interface" (in the "DHCP6 Client Configuration" section).

                I hope to reach a point of having confidence in this patch so that I can submit a pull request. I'm confident in the work-round used for Issue 2 (a proper fix needs changes in mpd5). Though I now believe I understand Issue 1 well, I would like some additional user experience of the fix for Issue 1 before submitting a pull request because of the complexity of the underlying issues.

                  I've posted a link to this thread in the 2.3-BETA forum, in the hope of further feedback on these issues.

                    Well thats odd…

                    On 2.3 with or without patch pfsense can communicate via IPv6 with outside world but LAN clients cannot.

                    What?

                      What?

                      Your config & data could make it interesting ;)

                        Upgraded from 2.2.6 to 2.3 rebooted 2 times all was working.
                        Then I just saved pppoe iface and now only pfsense can talk ipv6 hosts not.

                            Your PPPoE configuration looks correct, assuming your ISP uses a similar configuration to mine (WAN IPv6 address allocated via SLAAC, static address allocation for local networks but you have to delegate the prefix from the ISP to install a route to that prefix) and you are allocating static IPv6 prefixes to your local networks from the correct prefix.

                            If this is what you are trying to do, you will need to enable Router Advertisements on your local networks unless you are installing a static route on each machine.

                            What is unclear is whether dhcp6c is running and, if so, what it is doing.

                            Can you run the four shell commands I introduced and explained earlier in this thread (either using SSH or Diagnostics -> Command Prompt), copying and pasting the results (as text) into a private message to me. These commands are:
                            clog /var/log/ppp.log | grep -A 1 -E -e 'IPV6CP: LayerUp' | tail -n 2
                            ifconfig pppoe0 inet6 | grep -E -e '( fe80::|nd6)'
                            ps -auwwx | grep -E -e '(dhcp6c|rtsold)'
                            clog /var/log/dhcpd.log | grep dhcp6c | tail -n 40

                            If you get no output from the second command, the interface might be called pppoe rather than pppoe0.

                            It would also help if you save your configuration, open it in a text editor and include the section between <interfaces>and</interfaces> in your private message. This section will be fairly near the top of the file. That's the most concise and accurate way to let me see your full interface settings. The <dhcpdv6>to</dhcpdv6> section would also be useful - this contains the DHCPv6 server and Router Advertisement settings.

                              I found the bug and it`s actually old one :) But upgraded :)

                              This is it: https://forum.pfsense.org/index.php?topic=90699.msg501975#msg501975

                              GUI generates WRONG .conf file.

                              I used this:

                              interface pppoe0 {
                               send ia-pd 0; # request prefix delegation
                               request domain-name-servers;
                               request domain-name;
                               script "/var/etc/dhcp6c_opt2_script.sh"; # we'd like some nameservers please
                              };
                              id-assoc pd 0 {
                              };
                              

                              And it`s working great now.

                              Gui generated this (WHICH IS GREAT BUT SEE BELOW)

                              interface pppoe0 {
                               send ia-pd 0; # request prefix delegation
                               request domain-name-servers;
                               request domain-name;
                               script "/var/etc/dhcp6c_opt2_script.sh"; # we'd like some nameservers please
                              };
                              id-assoc pd 0 {
                              };
                              

                              After I click APPLY CHANGES on pppoe interface this OK conf dissapears and few seconds later newly generated config appears (below one).

                              
                              interface pppoe0 {
                              	request domain-name-servers;
                              	request domain-name;
                              	script "/var/etc/dhcp6c_opt2_script.sh"; # we'd like some nameservers please
                              };
                              
                              

                              So GUI generates good config but apply button messes it up completley.
                              Just a heads up guys!

                                Can you try this in 2.3 and see if it happens there?

                                    Good catch!

                                    It would be worth comparing the entries in the relevant part of the <interfaces>to</interfaces> block of your configuration between the broken and working scenarios.

                                    I'm unclear whether this was ever fixed in 2.2.x.

                                      Ah, OK. My fault for not looking back more in the thread – the thread title is still 2.2.5.

                                          Ah, OK. My fault for not looking back more in the thread – the thread title is still 2.2.5.

                                          As I noted in the 2.3 board earlier today, the issues discussed in this thread relate to both 2.2.5/2.2.6 and 2.3. I'm not the original poster, so I can't change the thread title.

                                          @jimp:

                                          I'll leave that to maverick_slo - though there is already a post in the 2.3 board.

                                          Hopefully fixing the bug maverick_slo has found will help in the process of validating my fixes for the two issues discussed in this thread, so that I can get on with submitting redmine bugs for those issues and pull requests for the fixes.
