          That looks like the successful case. What does it show when it fails?

              Hmm, yet it is adding addresses and knows what the gateway is....

                  @stephenw10 said in IPv6 Issues since upgrading:

                  You must have a globally routable IPv6 address somewhere though.

                  Yes, I can understand that and I can ping IPv6 addresses from pfSense but not from any of the LAN clients. The LAN clients to have IPv6 addresses. I enabled "Do not wait for RA" in the WAN DHCP6 Options and this is how my system looks now.

                  The IPv6 gateway address shown for the WAN gateway in the GUI does not appear in the ifconfig results. Surely something is wrong here.

                    The gateway would be in the routing table not the ifconfig output. The only time you'd see it there is if it's a point to point connection like ovpn or ppp.

                    Can you ping out from pfSense's LAN side IPv6 address? If you can but not from clients it's probably a missing firewall rule. If not it's probably a missing route.

                      Not sure what you mean here. If I log into pfSense via SSH I get replies with "ping -6 google.com"

                      However I cannot ping from any LAN Clients that do have IPv6 addresses. Any ideas appreciated.

                        But can you ping out from pfSense using the LAN address as source?
                        It could be whatever is upstream from pfSense does not have route for that /56 it's passing.

                              @stephenw10 - Yep, here are the results.

                              64 bytes from 142.250.66.238: icmp_seq=1 ttl=121 time=6.232 ms
                              64 bytes from 142.250.66.238: icmp_seq=2 ttl=121 time=6.627 ms

                              3 packets transmitted, 3 packets received, 0.0% packet loss
                              round-trip min/avg/max/stddev = 6.232/6.369/6.627/0.183 ms
                              

                              So I need to find the issue with the LAN clients not being able to ping IPv6 addresses.

                              EDIT: And the IPv6:

                                Ok so pings from the /56 delegated subnet work so upstream routing is fine. And pfSense knows that subnet is on the LAN. So as long as your have firewall rules to allow it clients should be able to ping out from an address in that subnet.

                                Check the firewall logs for blocked traffic.

                                Check the clients have a default v6 route via the pfSense LAN.

                                  Thank you @stephenw10 for your assistance. I will do some checking.

                                  Can you explain how the clients get a v6 route? I have DHCPv6 Server disabled as that is what my ISP told me.

                                  Once again, I appreciate your time.

                                    They should see it via router advertisements. If they are getting an IP in that subnet then SLAAC must be working so I'd expect them to get a gateway/route.

                                    Not sure why your ISP told you to disable the dhcpv6 server though. You should be able to use both.

                                      This is a typical Windows PC that can't connect to v6 addresses.

                                        It doesn't have a routable IPv6 address from the /56 subnet so.... it can't work.

                                        Did you also disable router advertisements on the LAN? That needs to be enabled.

                                          Is this what you mean?

                                            Yes. Try enabling the dhcpv6 server again though.
