Be advised, ICMPv6 is *not* like ICMP in IPv4, and knowing what can be filtered, what to filter, and where to filter it is considerably more complex than in IPv4 - which, given the prevalence of broken PMTU-D alone, is apparently not well-understood in many quarters, heh.

Most software today is very much like an Egyptian pyramid, with millions
of bricks piled on top of each other, with no structural integrity, but
just done by brute force and thousands of slaves.
