      Try just setting gateway to none and try using the two IPV6 DNS I provided.

        why do you have your rules in floating and not on the actual interface - out of curiosity?

          The pfSense UI will not allow me to enter those DNS servers without configuring gateway interfaces.

          As for the floating rules, there's a few other VLANs which they apply to, I'm just not concerned with IPv6 on those VLANs.

            Thats strange to me…

            I have 5 interfaces and, up till recently "none" was selected for all my dns server interfaces.  IPV4 and IPV6.

            Anyway - obviously whatever box you are on is getting IPV6 obviously.  I assume you are not testing connectivity from pfsense, but rather are using the same machine you are attempting to browse the internet from?

              Correction, I was able to implement these without specifying the gateway interface and I got the same result.

              I also disabled the firewall on my workstation for good measure. Still fails the IPv6 tests.

                But your WORKSTATION is able to ping, for example, those two IPV6 addresses I gave you?

                  Yes, that is correct.

                    I've resolved this issue. The firewall rule IPv4+6 was not applying correctly. Listing an explicit IPv6 Any -> Any rule fixed the problem. I'll work to explore these rules in more detail.

                      Strange - Just to look into chrome, past this in your chrome browser:

                      chrome://net-internals/#dns

                      Then click "clear host cache"

                      Probably will make zero difference, but why not…

                      If that doesn't work, take a look to see if there is some strange rule in your firewall (or lack of a pass rule) that is letting ICMP pass but not allowing HTTP/HTTPS.

                        Ahh - so not passing IPV6 correctly (-;

                        Works now?

                          And again why do you have them in floating in the first place? Are they set to quick, rules in floating are for SPECIAL rules..

                          For example
                          " I'm just not concerned with IPv6 on those VLANs."

                          But you had a rule that should allow ipv6 out, which would be applied to ALL interfaces..  I don't recommend putting anything in floating unless it really needs to go there.
