      Again, please say who your ISP is. Someone else may be able to help better than I can. When I updated to 2.5.0 & 2.5.1, IPv6 just kept working.

        Well if your isp is pppoe based, would seem odd that their ipv6 would be just dhcpv6..

        Is the settings from before? As mentioned - who is your isp.. This will allow other users that have that ISP or have used them to chime in on any special settings.

        I would suggest you get with your isp for what settings you need for ipv6.

          Here is some setup info from a Canadian ISP that uses both ADSL and cable. Perhaps something here will give you some clues. As I mentioned, I haven't set up pfsense on ADSL, so I can't speak from experience.

            That's exactly how my ISP works, and that would apply to most DSL providers in the UK.

            I have it configured as above except I am only pulling a prefix.

              it is pppoe based

              After a conversation with my ISP ("CCC" in israel)
              They say I get an ipv6 address
              (Appears to them on the computer that I have an address)
              I just do not see it or something like that

              I did not touch or change anything in the ipv6 settings
              I always got an address automatically

              It could be that in version 2.4.5 it was different
              I do not know

                Are you getting a WAN address? Also, packet captures can do wonders when trying to solve problems. Try this:

                Shut down pfsense & unplug WAN cable
                Reboot pfsense and run Packet Capture on the WAN port, filtering on port 546 or 547
                Plug in WAN cable
                Post the capture file here

                BTW, it really can help if you mention your ISP, in case someone else here has experience with them.

                  Enable 'Debug' in the dhcpb6 client settings. Check the dhcp logs after connecting.

                  If you are pulling a prefix only you want see that unless you have an internal interface set to use it.

                    I wrote that my ISP is CCC IN israel

                    Are the settings that appear on the screenshots I uploaded correct?

                    Maybe there
                    I need to change something

                      Sorry, I must have missed that. However, I see you gave a prefix delegation size of 64. If your ISP provides only a /64, then you can't pass IPv6 onto your LAN. If the ISP provides a different size then you use that number. For example my ISP provides a /56, which I can then split into 256 /64s on the LAN side.

                        Yeah, I pull a /56 here with link-local on WAN.

                        You could pull a /64 and use it only on LAN. Make sure you are requesting the correct prefix size though. I have seen that fail if it's not exactly what the ISP is offering.

                          i try that again
                          And now I see the ipv6

                          why it says offline packetloss ?

                            Your ISP's router may not be responding to IPv6 ping requests. Maybe do a IPv6 traceroute (you might need to temporarily disable monitoring to do this, see below) and try using hop #3 or 4 as the monitoring IP address, or use something more global like Google DNS or something. Or you can change the gateway setting to disable the monitoring (System > Routing > [edit the IPv6 gateway] > check "Disable Gateway Monitoring"), though that might affect failover if you have dual WAN.

                              Or not use gateway monitoring. I don't use it, as it doesn't do much for most users.

                                updating
                                I returned everything to the previous state
                                Ipv4 only
                                Because for some reason everything works slowly
                                I currently will not use ipv6 maybe I will try again in a few months

                                  Yeah, that's typical of having partial v6 connectivity. Most operating systems will try to use it first if they think they have a v6 connection. If that is broken you have to wait for it to timeout before it tries v4 resulting in a pretty bad experience!

                                      You can probably configure the clients to use only IPv4 or use v4 by default.

                                      Otherwise you need to either have fully functioning IPv6 or none.

                                        While you can normally adjust a OS preference to ipv4 from v6. Some devices are more difficult than others, and can be difficult to actually disable completely.

                                        If you are having issues with ipv6 - the simple solution is just not provide it at all.. Which is easy enough to disable at pfsense. Its much easier to do that way, then trying to configure each client to not use ipv6 or prefer v4 over, etc.

                                        I don't provide any automatic IPv6 to any clients on any of my vlans. But I can configure clients on the vlans I have it enabled manually to use it..
