          @F022Y That is looking good, what do your LAN rules look like?

            This might be where it's gone pear shaped.

              @F022Y Have you tried Track Interface?
              Anyways you can not set the prefix to /128, it has to be /64.

              And your firewall rules on LAN look like what?

                I take this back, it looks like you did everything manually, which could be wrong entirely. 😉

                  Just running back through the setup wizard again to "default" it and in doing so the IPv6 Gateway shows as down.

                  04d0b2bb-e0a2-449a-a1af-86693dae7053-image.png

                  From the LAN firewall point of view very vanilla at the moment just defaults.

                    @F022Y Try DHCP on WAN and Track Interface on LAN. I see no reason why your WAN is "offline" now, "save" it again, to trigger it.

                        So trying to get some help from ISP (LitFibre here in the UK), connection is fairly simple.

                        Fibre into the property, ONT with an RJ45 running to their router of my PFsense box.

                        Addressing is via DHCP and DHCPv6 according to what i got out of their router.

                        55631173-04f4-4458-9658-b64ae6db3584-image.png

                        If i don't spoof the WAN MAC in PFsense i don't get my static IP with i presume is down to DHCP reservation but i'm now stumped, i have reached out to ISP incase there is a setting i need which clearly i've missed or if PFsense can't be used with them.

                          No, you have to scroll down a bit...

                            Sorry for the delay, work got in the way so couldn't down the connection then i think the little USFF pc i was using died so back to my good old ESXI host.

                            I tried the following configurations:-

                            WAN interface IPv4 DHCP (this stays the same throughout)
                            WAN interface IPv6 DHCP
                            LAN interface IPv4 Static IP (this stays the same throughout)
                            LAN interface IPv6 DHCP

                            WAN interface IPv4 DHCP (this stays the same throughout)
                            WAN interface IPv6 Track interface WAN
                            LAN interface IPv4 Static IP (this stays the same throughout)
                            LAN interface IPv6 None

                            WAN interface IPv4 DHCP (this stays the same throughout)
                            WAN interface IPv6 Track Interface LAN
                            LAN interface IPv4 Static IP (this stays the same throughout)
                            LAN interface IPv6 None

                            WAN interface IPv4 DHCP (this stays the same throughout)
                            WAN interface IPv6 WAN
                            LAN interface IPv4 Static IP (this stays the same throughout)
                            LAN interface IPv6 None

                            WAN interface IPv4 DHCP (this stays the same throughout)
                            WAN interface IPv6 DHCP
                            LAN interface IPv4 Static IP (this stays the same throughout)
                            LAN interface IPv6 Track Interface WAN

                            I'm afraid i'm not familar with DHCP from an ISP as i've always been a PPPoE user so still working it out.

                            I have left it in the following state:-

                            WAN interface IPv4 DHCP (this stays the same throughout)
                            WAN interface IPv6 DHCP
                            LAN interface IPv4 Static IP (this stays the same throughout)
                            LAN interface IPv6 Track Interface WAN

                            This isn't showing me a DHCPv6 address in the interfaces and IPv6 tests at thge likes of https://test-ipv6.com/ are still failing.

                              @F022Y There are, unfortunately, a bunch of ways to configure IPv6, instead of just one. You need to figure out what your ISP wants you to use. Your ISP will delegate you a /64 block to use on your LAN.

                              https://docs.netgate.com/pfsense/en/latest/interfaces/configure-ipv6.html
                              "The Track Interface choice works in concert with another IPv6 interface using DHCPv6 Prefix Delegation. When a delegation is received from the ISP, this option designates which interface will be assigned the IPv6 addresses delegated by the ISP and in cases where a larger delegation is obtained, which prefix inside the delegation is used."

                              Your recent photo above shows WAN tracking LAN which is backwards. (and the opposite of your text in the post)

                              Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
                              When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

                                You don't track LAN, but the WAN 😊

                                Also : tip of the day : never presume that things are working : check it.
                                The 'thing' that that get an 'IPv6' for the WAN interface is called "dhcp6c".
                                The same process also asks 'prefixe(s)' so your LAN (or more LAN's) can have their own dedicated /64.

                                First, goto System > Advanced > Networking and check

                                4bb0536a-c44d-441d-ba45-d2bf43b9d8a0-image.png

                                Next : goto Status > System Logs > DHCP
                                Your looking for a known process : dhcp6c (and not dhcpd which is the dhcp server process for your LAN interfaces).
                                You should see something like this (read from bottom to top) :

                                This pure rocket science langue shows that my upstream ISP router gave me one prefix :

                                IA_PD prefix: 2a01:cbaa:beef:a6dc::/64 and that one is 'mapped' (by the tracking) on my LAN interface as it's static IPv6
                                The rest of the 2a01:cbaa:beef:a6dc::/64 is used by the dhcp6 SERVER so t can hand out IPv6 out off this /64 pool :

                                My dhcp6 server setup on LAN :

                                6b38b183-9fde-445a-920d-fc5a4b0b2f44-image.png

                                and now my IPv6 capable devices on my LAN are all getting an IPv6.
                                Most of them have "DUID static" IPv6 leases, so my printers, NAS, servers etc always get the same IPV6.

                                My interfaces :

                                as you can (can't see actually - I've barred it) see, the WAN IPv6 which is the 'range' of the LAN of my ISP router.

                                Btw : My ISP says in its GUI that it has a /56 for me, that is 256 prefixes of /64.
                                But it only gives me one !!

                                That's why I have this :

                                d14eb37b-694b-43c9-9f80-a81dd0d296c6-image.png

                                I can chose only 0 of 0 - actually 1 out of the 1 available prefixes obtained (see logs above).
                                But "0" is an hex index here. as these indexes go from 00 hex to FF hex = 255.
                                So "0" is the first valid one.

                                Also : the fe80:xxxxx adresses are like RFC1918 : so just like 192.168.1.1 - we all have the same addresses.
                                A 'real' rout-able IPv6 start with 2xxx:xx:xx:xx:xx:xx:xx:xx:x

                                No "help me" PM's please. Use the forum, the community will thank you.
                                Edit : and where are the logs ??

                                    @Gertjan Yeah i clicked submit then noticed my screenshot error (took it while testing) and then had a server issue at work so had to stop "playing".

                                    Thats really helpful info and gives me something to work on, i'm a simple man of PPPoE so this is a new config type for me so it's all weird and wonderful.
