      I say again:

      Once the host sends a Router Solicitation, and receives a valid
      Router Advertisement with a non-zero Router Lifetime, the host MUST
      desist from sending additional solicitations on that interface, until
      the next time one of the above events occurs.

      DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

        It might be a good idea to just capture all ICMPv6 and not limit it to ff02::1.

        I use the link local address for the WAN interface and ICMP6. That works well and catches both multicast and unicast packets.

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

          Your ISP is broken.

          Yep, I've read the RFC and I think you're right.
          I've opened a ticket and I hope they will fix it.

          But my question remains: Why is the route reappearing after saving the settings page? :)
          The router is not receiving a RA.

            I'll bet it is.

              The ISP now sends RAs periodically, so this part is solved.

                Does the route now stay? You actually got someone there to fix it?

                    Almost unbelievable: an ISP that actually fixes its stuff? That indeed is noteworthy!

                      It's a small local (germany) ISP, offering FTTB for a reasonable price.
                      And you're right: You can talk directly with the technical staff, that's awesome! They're doing a great job!

                        I bookmarked this thread. Especially in light of the other "German ISPs are immovable objects" threads around here. Vote with your deutchemarks, people.

                          Problem is, that those small little pearls are mostly local ISPs in specific regions or cities. Even if I'd wanted to go all out and "shut up and take my money", it won't get me far. In most non-crowded places you're happy if you can get DSL with PPPoE or Cable from the same few companies. There are only some like e.g. DG / Deutsche Glasfaser / "german fiber" that will get you FTTH or FTTB.
                          So more often then not, voting with ones wallet isn't possible as no other/better service is available. ๐Ÿคท
