      ~~After updating to 2.2.1, my pfSense setup no longer assigns IPv6 addresses on the LAN side.

      pfSense itself works fine and can ping IPv6 hosts. Reverting to 2.2 restores IPv6.

      WAN Interface configuration: DHCP6

      • Send options: ia-pd 0, ia-na 0
      • Non-Temporary Address Allocation checked
      • Prefix Delegation checked
      • custom DUID

      LAN: Track Interface

      dhcp6c and radvd are running.

      A bug?~~

      Solved. Just a configuration error, not 2.2.1 related.

        Also noticed that post upgrade.

        That ZMQ doesn't seem to be working

        Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/20121212/zmq.so' - Shared object "libpgm-5.2.so.0" not found, required by "libzmq.so.4" in Unknown on line 0

        and

        sudo doesn't work

        $sudo
Shared object "libintl.so.9" not found, required by "sudo"

        Not sure if this is related.

          I seem to have the same problem.  WAN gets an IPV6 address fine, but LAN does not.  This is with Comcast, if that is relevant.

          WAN configuration is DHCP6, DHCPv6 Prefix Delegation size 60, and Send IPv6 prefix hint selected.  LAN is configured to Track Interface WAN.

            Must only effect native IPV6.  Tunnel brokers seem fine.

              @kejianshi:

              Must only effect native IPV6.

              Definitely not native in general, seems only DHCPv6+PD related. I'm looking into it.

                That will affect everyone using Comcast and Time Warner Cable + IPV6 I guess?

                  This is affecting all DHCPv6+PD setups not just Comcast.

                  dhcp6c config file does not have pd entry in it:

                  interface vmx0 {
        send ia-na 0;   # request stateful address
        request domain-name-servers;
        request domain-name;
        script "/var/etc/dhcp6c_wan_script.sh"; # we'd like some nameservers please
};
id-assoc na 0 { };

                    Ignore my last post. Forgot that you need to apply WAN after you change LAN settings for DHCPv6+PD to work. Working fine here on AT&T.

                    dhcp6c config file:

                    
interface vmx0 {
        send ia-na 0;   # request stateful address
        send ia-pd 0;   # request prefix delegation
        request domain-name-servers;
        request domain-name;
        script "/var/etc/dhcp6c_wan_script.sh"; # we'd like some nameservers please
};
id-assoc na 0 { };
id-assoc pd 0 {
        prefix ::/64 infinity;
        prefix-interface vmx1_vlan10 {
                sla-id 0;
                sla-len 0;
        };
};

                    Guys who are having issues, can you post your dhcp6c config file: /var/etc/dhcp6c_wan.conf
                    It would also be helpful if you ran dhcp6c in debug mode and posted the output. In order to do that kill existing dhcp6c and execute "/usr/local/sbin/dhcp6c -f -d -D -c /var/etc/dhcp6c_wan.conf -p /var/run/dhcp6c_vmx0.pid vmx0" after replacing interface names in the command.

                      Here's one of the broken setups:

                      /var/etc/dhcp6c_wan.conf:

                      interface em0 {
        send ia-pd 0;
        send ia-na 0;
        script "/var/etc/dhcp6c_wan_script.sh";
};
id-assoc na { };
id-assoc pd { };

                      /usr/local/sbin/dhcp6c -f -d -D -c /var/etc/dhcp6c_wan.conf -p /var/run/dhcp6c_em0.pid em0:

                        Ah come on :)
                        I have native IPv6 and WAN (pppoe) and now after upgrade LAN cannot connect via IPv6 anymore.
                        Am I affected with same problem?

                        From LAN I can reach pfsense but I cannot reach internet.
                        From pfsense WAN (pppoe) I can reach internet via IPV6.
                        =??

                          If you already did a reboot and its not working then, yes,  I'd imagine you are most likely affected.  I think you are the first to mention ppoe though.  Congratulations.

                          Getting IPV6 on the WAN with DHCP?

                            Yes, DHCPv6 PD, ip trough ipv4, do not request IP addr. and that`s it.
                            After upgrade and reboot PPPoE WAN can ping IPv6 internet but LAN does not come trough FW…

                              Just to add to the mix … My Internode (Australian ISP) IPv6 config is working fine using a tracked PPPoE WAN with DHCPv6 PD. An IPv6 address is correctly assigned to the LAN interface.

                              Interface IPv6 config
                              Use IPv4 connectivity -> Yes
                              Request only prefix -> Yes
                              DHCPv6 Prefix Delegation -> 56
                              Send IPv6 prefix hint -> No

                              /var/etc/dhcp6c_opt1.conf:
                              interface pppoe1 {
                              send ia-pd 0; # request prefix delegation
                              request domain-name-servers;
                              request domain-name;
                              script "/var/etc/dhcp6c_opt1_script.sh"; # we'd like some nameservers please
                              };
                              id-assoc pd 0 {
                              prefix-interface vr0 {
                              sla-id 0;
                              sla-len 8;
                              };
                              };

                                WebUI generates WRONG config file this is for sure.
                                WebUI generated:

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

                                But is should be:

                                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 {
};

                                I created my own .conf file and specify it at DHCPv6, restarted PPPoE and it works.

                                      WAN configuration is DHCP6, DHCPv6 Prefix Delegation size 60, and Send IPv6 prefix hint selected.  LAN is configured to Track Interface WAN.

                                      Working fine here (also Comcast) with that same configuration.

                                        It appears that only guys that are using advanced DHCPv6 configuration options are having problems. It would be interesting to hear why you are using advanced options instead of basic options because looking at your configs a lot of things do not make sense.

                                        There are couple things to keep in mind when you select advanced DHCPv6 options. First, it overrides non-advanced options so they really don't do anything. Second, settings on the LAN interface, making it track WAN for example, are ignored as well

                                        Majin3 - your dhcp6c config file does not have 'prefix-interface' statement inside of it, thus even though log you posted shows us that prefix is returned from DHCPv6 server dhcp6c simply ignores it because it does not know what to do with it. I looked at the code and I don't see how this could have worked with 2.2. If you have reverted to 2.2 and could post /var/etc/dhcp6c_wan.conf that might help a lot. Also, how did you configure custom DUID?

                                        maverick_slo - did you use advance options when your setup worked? Configs that you posted have 'request domain-name-servers;' and screenshot that you posted has empty 'Request Options' field. That does not add up because in order to have 'request domain-name-servers;' in config you would need to specify that in 'Request Options' field. And just like in previous case if you have empty 'id-assoc pd 0 {};' in your config file, prefix does not get assigned to LAN, unless you configure it manually using static assignment.

                                          I have PPPoE also and have to use the settings in the attached image before I can get my /56 PD to work as the normal settings did not work.

                                            Ugh, you are right. Seems like it was a configuration error after all and loading my snapshot of 2.2 was also loading a working DHCP6C configuration (with prefix-interface defined) I seem to have broken at some point…
                                            Thank you and sorry for wasting time. No relation to 2.2.1 whatsoever.
