      Ok, that all makes sense.

      A bit of a pain to achieve though. It took countless refresh attempts to get beyond this stage, until pfSense 'found' the things it needed:

      Still, it eventually 'just worked' and all loaded just fine:

      It didn't crash on first interface change, so at least there is that. 🙃

        Ok, cool. There's a routing issue with v6 at the pkg server our guys are working on. And we know you're using v6! Should be resolved shortly.

        Let us know if you hit it in 23.09. Thanks 👍

          Will do.

          It survived 5 interface changes with no issue, before I ran out of time / actively complained at.

            The issue persists with the latest dev snapshot. This crash was triggered by taking the WAN interface down & up again:

            All hopes of an accidental fix were suddenly dashed...

            I have full logs, should you need them.

                  This seems a little odd too - the QDrops on ipv6:

                  The system has only been up a little while and nowhere near saturation - just background traffic really. I would not expect to see any QDrops; IPv4 is fine but IPv6 is ???

                  ..and from the previous log; all fine but for IPv6 QDrops:

                    With the news that the fix for this will probably have to wait until 24.03 (ie 6-months away) does anyone have suggestions for a non-pfSense router OS?

                    I currently run a Netgate 6100 so I will have to run a new OS on different hardware too but I do have a potential mini-server I can use arriving sometime in Oct; so that will give me something to host on. I also intend to keep my toes in the pfSense world whilst I wait this IPv6 / interface issue to be resolved but this is not something I can do when I'm away.

                    So what is my least-worst option for a router OS that is reliable for high-bandwidth PPPoE WAN and IPv6?

                    ☕️

                      Are you able to test a debug image if we generate one to get more info on this?

                      Despite absolutely hammering the connection I have here I have yet to make it fail. 😞
