      Given you have a /32, why would you want to use NAT, when you have so much public address space? Just assign another /64 to those computers. The reason for NAT was to get around the IPv4 address shortage and there's no shortage of IPv6 addresses.

        @jknott security..

        You don't put public it's on a local secure lan.

        Also want it to connect to other internal networks on ipv6

          That's what firewall rules and routing are for. If you don't enable that network to route to the Internet, it won't. If you do, you use appropriate rules to allow only what you want. Claiming NAT protects you is a false sense of security.

          BTW, you can route between public and unique local addresses just fine. I do it here.

            What do you have setup for NAT for configuration?

              This is my basic setup

              CISCO vLan IP as GW - 2b02:2bc8:1:1::1/64

              pfsense details
              pfsenseIPv6 Gateway - 2b02:2bc8:1:1::1
              WAN IPv6 - 2b02:2bc8:1:1::3/64

              LAN IPv6 - fc00:1:1::/64

              NAT Outbound Settings

              Interface - WANv6
              Source Network - fc00:1:1::/64

              it pings the WANv6 interface IP from fc00:1:1::/64 pc's

              and when i ping from pfsense i can ping fine as well but not on nat.

              So we want the fc00:1:1::/64 to ping the 2b02:2bc8:1:1::/64 range

              When i dont set the WAN IPv6 on the interface i can ping fine, if i set the gateway i cant ping

              Firewall rules are all ok and IPV6 is allowed and icmp enabled

                    I don't use NAT on IPv6 at all. No need for it.

                      @chrisjmuk said in IPv6 LAN to WAN NAT:

                      would i need to create any static routes?

                      Routing between networks directly connected to pfsense is automatic. Networks beyond that require manually configured routes. The exact method depends on the client. i.e. Linux, Windows, OS/2, etc.

                        @jknott found the issue, was stuck in the state, needed to clear.

                        another issue is that i can cant ping a certain ip on my cisco and it cant ping the pfsense, ::1 but can ping ::20 no idea why.
