    Why is the IPV6-WAN so much slower than the IPV4-connection!?

      Since a long time, so not specially related to 2.7 I notice that the IPV6-WAN response times are much slower than the equivalent IP4-one's

      At the top line IPV4 at the bottum IPV6.

      Can someone explain if that is normal and what is causing those differences?

        This is probably due to your ISP. On my systems, there is no difference between IPv4 and IPv6.

          @louis2 Most probably your ipv6 gateway is slow on replying to pings. Not necessarily a problem.

          Try pinging something else at the gateway, maybe your next hop if you traceroute a bit, and see if it gets any better

            The numbers shown are not a speed indication.

            Its shows the result of a up-down ping trajectory.
            And you get it : not some destination at the other side of the world.
            The tools used, "dpinger" pings probably your upstream 'next-hop' local ISP router next to the pfSense device : that will produce very low values : you are testing the connection between pfSense and your ISP router : and that doesn't make sense.

            Edit your System > Routing > Gateways > Edit and add a more reasonable IPv4 :

            0301fa99-fc8c-44a2-8e89-085d21ec1d71-image.png

            or any other known, rather close but on the internet, IPv4 that you know will reply on pingv4.

            Same thing for IPv6 : where is it pinging to ?

            No "help me" PM's please. Use the forum, the community will thank you.
            Edit : and where are the logs ??

              I just do not know which addresses are used by default. Could be the dhcp-provided DNS-addressess ????

              What ever I did a ping test to Google and Cloudfare results below. Not so much differences between IP4 and IP6

                On my system, the addresses are the respective ISP gateway addresses.
