      They specifically mentioned to make sure the following was enabled:

      • Allowing large ICMP
      • Allowing v6 ICMP across the network

        @jknott No it's not. Still useful to have for pfsense itself as a pseudo-privacy layer e.g. for DNS requests, and I assume there is at least some good if non-essential reason it's part of an RFC and done by default by my ISP.

          @ijeff I have no idea how that would help you. AFAIK by default pfsense has rules that allow the bare minimum essential IPv6 ICMP traffic, so that shouldn't be the cause of your issue.

            I think you're right, it looks like pfSense is doing everything it needs to by default.

            I've been referred to this bug which seems to explain the exact issue I'm having. My ISP and the ISP mentioned in the bug actually use very similar network hardware (Cisco Nexus) so it may be completely related to that...

            I might wait until 2.5.0 is released with this bug fixed before trying further troubleshooting...

              I've upgraded to 2.5.0 today and will monitor and report back.

                No further issues since upgrading to 2.5.0. Looks like the bugs have been squashed!
