      @sirsilentbob That's very kind but no need for any paypal etc I am glad to hear this might be useful.

      So yeah without applying the patch you'll be missing a function called create_interface_ipv6_cfgcache() which is so the script can be a little more efficient and check if the IP is the same or not before applying any redundant changes.

      It's not strictly necessary, so if you can't apply the patch using System Patches (probably due to differences between CE and Plus) then you can just comment out the line using 2 forward slashes //. I added a note about this to the README on github. Hopefully after doing that and rebooting it shouldn't cause any more crashes.

        @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

                    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 I'm running out of ideas. What does the command below output?

                                sh -c '/sbin/rtsol -DF igb0 2>&1'

                                  @luckman212 said in FIOS - getting /56 PD via DHCP6 but no V6 is assigned to WAN:

                                  sh -c '/sbin/rtsol -DF igb0 2>&1'

                                    @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...
