      Only issue is DHCP6 Gateway is pending.

      That could be due to what you're pinging. While you can ping a link local address, your ISP might not have configured it to respond. That's the case with my ISP. What I did was run a traceroute to Google and picked the first global address to use for the monitor.

        I can ping the same addess from the pfSense CLI, so should it not also work in the Gateway Monitoring.

          You'd think so. Did you enter the address for the gateway? Or just leave the box blank. It will default to the gateway address, so you don't have to enter anything. You could try putting some working GUA, that you can ping, in that box.

            Gateway is set to dynamic and cannot be changed.

            Sorry, I do not know how to do that.

              First, go to a command prompt in pfSense and traceroute6 go Google:
              traceroute6 google.com
              traceroute6 to google.com (2607:f8b0:400b:807::200e) from 2607:f798:804:90:3899:8d05:91dc:56e3, 64 hops max, 28 byte packets

              Then ping6 the address in line 2 to see if it works:
              ping6 2607:f798:10:10d3:0:241:5615:221

              It does, so that address can be pasted into the monitor address box.

                  What happens if you disable gateway monitoring for IPv6?

                      Well, you obviously have a problem with how the monitor is configured,but I don't know how at the moment. Regardless, don't worry about it, as for most users it's not used. All I can say is use the default, if it works or plug in an address you know works.

                      Anyway, you appear to be up & running with IPv6.

                        I think you're correct. Would it help removing and adding it back in?

                        Thanks again for all your time and putting up with me.

                          As I mentioned, you don't have to put anything in, provided the gateway can be pinged. It's only when it doesn't that you have to provide some other address.

                                  What pictures are you talking about? I already included examples of me doing it.

                                      Given the pictures are already there, what would it accomplish to provide more? I often post pictures when I think it would help.
