I should note I've already had ICMPv6-related issues in the past: I had to turn on router-solicitation and router-advertisement to get a global ipv6 address at all. What should be enabled is still a bit arcane to me.

When you don't understand ICMP(v6) you should not block it in your
firewall, as this will cause the weirdest of problems.
