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

      It would also be nice to have the option for interfaces to have a 2nd IPv6 address, like for ULA addresses and subnets. Say you want to use that ULA subnet over VPNs or whatnot.

      You can certainly do that. I have both ULA & global addresses on my network.

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

        You do it with Virtual IP?

          I would expect to be able to do that using IPAliases, yes.

            Yeah can't route stuff through an IP Alias though.

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

                  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.
