      but just confirming, there is not way with 1:1 or NPt to use the ISP range (which is dynamic) and set the internal network of FD00.

      Maybe there is, haven't tried it yet, because you can use the dynamic ones too (with some caveats).

      One thing one could try is maybe this, make an unused VLAN and give it a dynamic prefix via track interface. Then use that prefix to do NPt with your interface which is using the ULA and see how pfSense respond.

      In the future it would be nice if pfSense would allow to reserve prefixes just for that cause. Or find another way of fixing the problems when using dynamic prefixes.

        Not that I'm aware of. Regardless, NAT is a bad idea on both IPv4 and IPv6. It's needed on IPv4 due to the address shortage, but not IPv6. However, your prefix should not be changing, provided Do not allow PD/Address release is selected, though I know there are some stupid ISPs that don't respect it. I've had the same prefix for a few years and it's survived replacing both the modem and the computer I run pfSense on.

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

          I don't have this option anymore or am I blind...

            Yes. It's on the WAN page.

                How old is your version of pfSense? It was added a few years ago. It wasn't there when I started using pfSense around 6.5 years ago, but was added not long afterward. Before then, simply disconnecting/reconnecting the WAN cable was enough to cause a prefix change.

                  How old is your version of pfSense?

                    I'm on 2.6.0. I have no experience with 22. Perhaps you should contact the Netgate people about this.

                      Maybe @stephenw10 can confirm, that that option (Do not allow PD/Address release) is missing in 22.05-RELEASE.

                        It is set on for me per my above post. But, I am on 2.6.0 (which is 22.2 config rev).
