      Re: [Source IPv6 Address in Multi-WAN is WAN address](not actual LAN IPv6 address?)

      I recently made a config change to rectify an issue I brought-up in the IPv6 forum, but now I am getting daily kernel panics/page faults. Any suggestions?

        Crashed again, wish I knew why. Guess I'll re-enable IPv6 NAT? (how that makes sense, I am not sure)

          found this in the log immediately upon reboot after the latest crash:

          Just prior to the latest crash, I don't see anything particularly compelling in the logs, just a few devices trying to communicate to/from Facebook on IPv6 via their link-local addresses (weird).

            I also had a page fault somewhere in IPv6. I too use Multi-WAN and I use NAT for IPv6.

            At the time of the crash IPv6 was failed over to my backup gateway due to the issue I reported in #12947.

              Crashed again, wish I knew why. Guess I'll re-enable IPv6 NAT? (how that makes sense, I am not sure)

              textdump.tar.0

              info.0

              The backtrace here looks close to https://redmine.pfsense.org/issues/13938 -- close enough I'd try the workaround there to see if it helps.

              I also had a page fault somewhere in IPv6. I too use Multi-WAN and I use NAT for IPv6.

              At the time of the crash IPv6 was failed over to my backup gateway due to the issue I reported in #12947.

              textdump.tar.0
              info.0

              This looks close to https://redmine.pfsense.org/issues/14077 but there isn't a fix available for that one yet.

                @jimp Thanks Jim, I'll keep an eye on that one.

                  thanks jimp, I added that tunable... do I need to reboot for it to "take effect" or is it instant?

                    It should be immediate

                      reading through the redmines that were linked... I wonder if there's anything to the fact that I just recently disabled NAT I was inadvertently doing on IPv6, then within a day I started having the crashes. seems almost too coincidental. (I have not re-enabled NAT on v6 yet and probably won't unless I have another crash in which case I may just downgrade temporarily)

                        almost 3 days of uptime, no page faults so far!
