      Shouldn't it work this way

      Yes. So you might (also) have different problems.

        I'm just asking to understand the process: Shouldn't it work this way if it's the thing you guys told about?

        My prefix hasn't changed in almost 7 years, so I don't have much experience to work from. However, I would expect the pfSense LAN interface to show the new prefix and the router advertisements should tell other devices on the LAN what the new prefix is.

        I haven't lost my mind. It's around here...somewhere...

          I don't know, I still don't think it's a prefix problem because I used it as it is for a long time without a single problem and now I simply can't connect to the internet with it.

          But I can't see any problem on my settings and my ISP says there's nothing wrong on their side either. I'll just turn my IPv6 network completely off until I figured it out because it really causes my network go crazy.

          Do you have any recommendations to check or solve?

            @crazypotato142 Check the IPv6-addresses closely, are they really using the same prefix or do they differ. It must be the same prefix as pfSense LAN has.

            In Windows use ipconfig /release6 and then ipconfig /renew6 and watch out for problems.

              @Bob.Dig They are like this right now:

              Note: I can't ping an IPv6 address over pFsense interface either.

                @crazypotato142 The first address already looks wrong. At least the prefix is the same.

                  pFsense itself can't connect to anything over IPv6 either. I can't use IPv6 ping, not even get into the Update page cuz Netgate has IPv6 addresses for their website.

                    That screams for a big problem, might be your ISP at this point.

                      I'll test it with their default router and keep here updated. Thank everyone for the help.

                          I saw in your settings that you request a prefix only, not a WAN address. You might have to specify your LAN interface as the source address. You use the -s option for that.

                            How do I do that?

                            Also I didn't do such a thing after we got my IPv6 in this thread

                              I don't know, I still don't think it's a prefix problem because I used it as it is for a long time

                              In an earlier post I suggested you capture the DHCP6 sequence to see what prefix you're assigned, to see if it's what's actually being used. Have you tried that?

                              In the capture you'll see 4 packets:

                              1173e38f-fdff-42d1-8e52-c99545293ff1-image.png

                              Then, in the last packet, should be something like this:

                              2b23ee5b-92e5-46c6-8bc4-d7c7e82c6bf6-image.png

                              Compare the prefix with the one your network is using.

                                Package Capture stops when I plug the WAN cable. I'm doing it according to this: https://forum.netgate.com/topic/172514/capture-full-dhcp-or-dhcpv6-sequence

                                Update:
                                It doesn't work with the default router my ISP gave either. Prefix and IPs everything seems fine but nope, it still doesn't connect. I also checked Windows ipconfig while on it and it just showed single IP for each, prefix matched as well.

                                  I just tried and it works fine here.

                                  Do you have a switch that you can use to make a "data tap"?

                                    @JKnott I'll try it again later today.

                                    Unfortunately no, I don't have a managed switch.
