        You have two router in series, cascading networks. ?

        If you want public IPv6 on your pfSense-LAN, then your pfSense-WAN have to request your ISP-box with DHCP6-Client for a prefix&subnet first ?, provided your ISP-box can function as a DHCP6-Server…

        IPv6, no pfSense issue forya. Your ISP-box has the /56. Your pfSense is a slave with other LAN subnet-value and local prefix between /57 and /63.

        Your pfSense-WAN on mask /56 doesn't look correct. (but /64 or /128).

          Sounds like your settings are OK. If your LAN IP address can ping the upstream gateway then your local setup is fine, and probably even the routing at your next hop is OK, but it sounds like maybe the routing/rules upstream from you is broken.

          A traceroute6 to your WAN and LAN IP addresses both stop at your gateway. I'd normally expect it to work if all that is fine, unless the ISP is filtering the traffic.

          If you can ping your gateway and a traceroute from the outside to your LAN subnet is OK, then the routing is probably OK at the ISP end of things.

          Sure you used /64 for the prefix on all your interfaces?

                          Consider: your ISP-Box supplies on request, you probably can not grab a number you like…

                          SO, don't do all static, but do DHCP6 from pfSense-WAN to your ISP-Box. Then read reply #19 again...

                              You may read & understand to request a prefix /62 for pfSense from ISP-box (/56) for the pfSense LAN's. The WAN address mask (/64 or /128) no problem for that, just an intermediair. The LAN's are each with a unique subnet and mask /64.

                                  Why are you now trying to divide up a /64? You'll have a horrible time trying to use IPv6 with an allocation narrower than /64 on a LAN unless everything on that network supports address allocation via DHCPv6. Some devices only support SLAAC (such as Android devices, also Windows XP if you still use it and haven't installed a DHCPv6 client). SLAAC requires you to advertise a /64 (and exactly a /64) for things to work correctly.

                                  Are you running router advertisement on your LANs (Services -> DHCPv6 Server/RA, Router Advertisements tab)?

                                  I'd start by working out what your ISP supplied box offers. If it will allow you to delegate prefixes via DHCP-PD, your task becomes a lot easier. You've said you can't bridge this device, but does the ISP allow you to replace it with a DSL bridge and use PPPoE or similar?

                                    I have a similar issue where NDP proxy would be really useful.

                                    My colo provider gives me a /64 for my rack. I use NPt to do 1:1 NAT so I can have my pfsense firewall while still allowing machines behind it to have IPv6 connectivity.  This works, but I have to manually configure a virtual IP for each machine. I'd really like to avoid that by just proxy NDPing the whole range.

                                      Don't do that. NAT sucks. The main point of IPv6 is to do away with NAT. Make them give you another /64 and route it properly.

                                        I can try, but I don't have much leverage over them. They're the central IT department for the university I work for.

                                        As an aside, this is what I really don't like about IPv6.  It takes away the ability for end users to do stuff on their own.  NAT was invented to begin with because ISPs weren't interested in giving out extra subnets; now we're back to begging for them to give out static routes again.  I remember the "bad old days" when ISPs would only allow you one computer per Internet connection…one of IPv6's goals seems to have been to enable that kind of restriction again. :/

                                          IPv6 was designed to eliminate the need for any of that. Any ISP that doesn't give you multiple subnets is implementing IPv6 incorrectly. IPv4 was scarce, IPv6 is not. There is no reason (aside from pure greed) that they should not give you at least two /64's with one routed to your address in the other.

                                            The response to my ticket asking for another routable block was "why don't you use NAT?"  Trying to get it escalated to someone who at least understands the difference between IPv4 and IPv6.  ::)
