        Hmm, to do what? You can source traffic from it. You can add a ULA gateway on it and route through that.

            @Zermus said in NAT66 support is needed and 2nd interface IPv6 IP option for ULA would be nice:

            we need NAT66 lol.

            I think pfSense already does that. But who is we?

              If I understand it correctly you can't use NPt because the translation prefix conflicts with the assigned prefix on the WAN?

                  You can just add a 1:1 NAT rule between the VIP and the ULA address. I tested that here and it works as expected.

                          You do it with Virtual IP?

                          I have both global and unique local addresses on my LAN.

                          PfSense running on Qotom mini PC
                          i5 CPU, 4 GB memory, 32 GB SSD & 4 Intel Gb Ethernet ports.
                          UniFi AC-Lite access point

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