      If I go to test-ipv6.com

      What issues?

      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...

        I knew I'd miss something.
        IPv4 tests are OK. Any other test will time out after 15 seconds.
        Opening one of the idividual tests in it's own tab will time out.

          Sounds like you don't have IPv6. When you go to ipv6.google.com, are you able to do anything?

            they can look up IPv6 DNS (pi-hole server

            via GUA or some link local address? You can look up a IPv6 address ie AAAA over IPv4..

                Help?!

                Help offered - I'm also with iDNet (good idea going with a quality ISP over a cheap one) so can offer any settings you need. ๐Ÿ‘

                    @Gertjan You're right - I'd love to see those!
                    This is what I get:

                    If I I try one of the URLs which times out (e.g. the vm3 link) as an individual page, it still times out:

                    If I try a test-netconnection on port 443, it's OK:

                      @JKnott I get the usual Google page with ipv6.google.com. If I ask it what my IP is, it responds:
                      2023-06-15 19_50_19-what is my IP address - Google Search โ€” Mozilla Firefox.png

                      If I go to ifconfig.co, it tells me the same:
                      2023-06-15 19_49_50-What is my IP address_ โ€” ifconfig.co โ€” Mozilla Firefox.png

                        OMG - it was in there!
                        You're using FTTP (I think), but your point about MTU got me thinking....
                        The WAN was set to 1492 by the ISP. The LAN defaulted to 1500. I changed this to 1492 et voila!

                        THANK YOU SO MUCH!

                        @JKnott @johnpoz @Gertjan Thank you for jumping in and helping. It was the MTU size which was killing packets... I finally got there!

                          No problem at all. It does not matter if you are on FTTP or not, the physical link on the WAN to your ADSL/VDSL2/G.fast modem should be 1508 MTU, allowing a normal 1500 MTU to traverse wearing the 8-byte PPPoE wrapper (ie as per my settings).
