      You're using PPOE.
      The word 'MTU' means something to you ?
      Try lowering it - there are ping tests that show you when packets are fragmented (MTU to big) and when you lower the MTU, you'll hit a moment when they stop being fragmented. That will be your perfect WAN MTU setting.

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

        I have an MTU of 1492 as my ISP suggests.

          Try something basic. Can you ping the the IPv6 sites? It could be your ISP has a problem, even though you have valid addresses. I ran into that a couple of years ago. Regardless, a browser should try IPv6 first and then IPv4 if it fails. Is that happening?

          PfSense running on Qotom mini PC
          i5 CPU, 4 GB memory, 32 GB SSD & 4 Intel Gb Ethernet ports.
          UniFi AC-Lite access point

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

                  A browser should :

                  150f3567-a68d-48a8-a5b7-e59f072e5145-image.png

                  Use IPv6 (if it is available** on the device)
                  and if no answer, it should fall back to IPv4 (if available ;) )

                  available means : it should have some sort of IPv6 starting with ff.... or 20..... and it has probably multiple IPv6. Execute "ipconfig /all" or ifconfig on your device to check.
                  It should know about a IPv6 capable gateway, which should point to pfSense - and a DNS (also a the LAN IPv6 of pfSense)
                  Or : if you have a mouse :

                  7bd8f6c3-3a41-4d3e-8357-392c64e32181-image.png

                  and you can check the status also over there which shows everything.
                  All this to check if your device is all set up.

                  On the pfSense side :

                  c0c5781d-e75a-4e8f-b6d5-4515ef095fe5-image.png

                  As I have a IPv4 (only) WAN and a 'special' interface that gives me IPv6, as my ISP doesn't know what IPv6 is ....

                  Another test :
                  http://test-ipv6.com/

                        suddenly i can open webpages with ipv6 but not all of them
                        i tested disabling ipv4 on my client (pc) network card and leave only ipv6

                        i.e. ipv6-test.com not opening
                        the netgate forum opens fine
                        some other local forum page not opening
                        ipv6.google.com opens
                        youtube opens
                        google.com opens

                        Any clue what is going on?

                        no logs at the firewall
                        i can only see the ip:53 request and the reply after that no logs

                          if it is pppoe
                          go to the interface and set MSS to 1452, test and see if it's better.
                          eventually lower the value to 1440

                            After another call to my ISP the problem finally solved!!!
                            There was nothing from my side!

                            Thank you all for your support.
