      @luckman212 Oh I DID apply the patch, but it's still giving those hourly errors.

      I can comment out the specific line, but before I do, anything else I should modify or anything else you need info on? I guess I could go from CE to plus maybe next weekend or so...

        @sirsilentbob You only applied the companion patch which activates the automatic assignment (so a cronjob isn't needed.)

        You still need the other patch from https://github.com/pfsense/pfsense/pull/4595/ to bring in the missing function.

        If you don't want to (or can't) apply that one, then I suggest just commenting out line 57 as mentioned in the readme and going with a cronjob every XX min.

          @luckman212 Ok. Sorry, I misunderstood! I thought there was just the one.

            @luckman212 Hi,

            Nice work. I follow all the instructions and I have when a run the command assign_gua_from_iapd.sh, there are 2 error the first one "specify an interface", so then run the command specifying the interface assign_gua_from_iapd.sh igb0 then I had the follow out put "waiting a few seconds for IA_PD no IA_PD detected in logs". I am on Verizon FiOS and I have access to IPv6. So what I am doing wrong?

            Thanks

              @betapc What prefix are you requesting in your FIOS WAN Interface config? I just checked because it's been a while since I looked at this script tbh. The script is hardcoded to look for a prefix delegation of /56 (if you request a /64 for example, it won't work).

              How does your config look? For example, here's mine
              4dc8c224-c0e2-4080-8efb-1e3300acddc4-image.png

              Can you run this command from your firewall console and post the output?

              grep 'IA_PD prefix' /var/log/dhcpd.log

                @luckman212 Thank you for replied. I run the command in the console and the output is nothing, just a blank line.

                I am using FiOS and have same setting requesting /56 prefix delegation like in your screen shot.

                The only thing is for my LANS show like this "SubnetPrefix Delegation (2600:xxxx:xxxx:xxxx::/64)". I don't have any control about that part.

                Screenshot 2023-01-26 055624.png

                Thanks again for your help.

                  @betapc Something seems to be missing from your dhcpd.log. Mine looks like this

                  ae0c5151-960a-4b46-be8a-354acbc188a5-screenshot_jJHk9EoW.png

                  Are you doing something unique with your logging setup? What does tail -n50 /var/log/dhcpd.log show?

                    I don't think so. I have default setting for logging.

                          @betapc Hmm. I wonder if you're hitting this known bug affecting Alcatel ONTs + Intel PHYs by chance? Could you retry after disabling Hardware Checksum Offloading at System → Advanced → Networking?

                            @luckman212 I already have disable the checksum, I have all 4 checks as show in the picture above, when I run the ifconfig -m igb0 command.

                                  @betapc Is that the full output? Doesn't seem like you're receiving a PD in those frames.

                                  There should be lines like this

                                  rtsol: ndo->nd_opt_type = 25
rtsol: ndo->nd_opt_len = 3
rtsol: nsbuf = 2600:4041:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx
...
rtsol: write to child = 2600:4041:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx(39)

                                    @luckman212 Yes that is the full output, I don't see those line. I have IPv6, all my LANs received IPv6 and I can connect to the internet with IPv6 only. I release all the IP address and renew same didn't change anything.

                                    So, what do you think will be the problem here?

                                      @betapc I'm not sure. Do you have debug enabled for dhcp6?

                                          @betapc I'm sorry but I'm really not sure where to point you next. Maybe someone else has an idea...

                                            @luckman212 Thank you very much. I will wait for pFsense version 23.01 to be release and see what happen when I do a clean installation.

                                            Do you think ipv6/dpinger fixes from PR #4595 will be included on version 23.01? and maybe a fix to handle IPv6 to WAN for cases like this on Fios?

                                            Thank you for your contribution to pFsense.
