      My ISP also uses RAs, but also DHCPv6-PD to assign my local prefix.  On the WAN side, while it's assigned a global address, it uses a link local address for the router.

      When i setup my WAN on DHCP i do get a IPv6 address.

      @marjohn56:

      Your ISP is doing something similar to mine, how is the initial negotiation for IPv4 handled is it PPPoE?

      What version of pfSense are you running, It may be in an earlier message but I did not see it.

      We have been given a subnet of IPv4 addresses so no DHCP or anything at the IPv4.

        Silly I know, but have you allowed IPv6 in System->Advanced->Networking?

            If you leave the WAN side as dhcp6 you should get something. Set it to dhcp6 and then look at the dhcp logs and look for dhcp6c entries, see if anything is there.

              I do, then i try to use the  2XX1:2XX0:5XX0::/48 on the LAN side but it still don't route.

                Set your lan v6 to track the Wan interface. Set up your dhcp6 server on lan too. You do not want the whole 48 on your lan, 64 is fine.

                    Telia added a route to my route for the /48 i have got and now it works. So the problem was that Telia didn't route the traffic back to my router.

                    Case closed! Thanks for all your help!

                      Do you now have multiple /64s available?

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

                        Good stuff, they are not the only ISP to have done that, seems a common problem.

                          Yes, they route the whole /48 to my router and i can split it to multiple /64 and my router takes care of that routing.

                            Good, that's the way it's supposed to work.  Now all you have to do is figure out what to do with the other 65,535 /64s.  ;)

                            BTW, I only get a /56 from my ISP.  :(
