      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.

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

                        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.
