>Too much of pain to figure out who is right and if/how ipv6 changed ICMP then let me make this easy for you: ICMP has become a vital part of the inner workings of an IPv6 network. You will break all kinds of functionality by dropping ICMPv6 packets. If you are concerned, then drop ICMP echo requests and replies, but absolutely do not drop any other ICMP packets or you'll be one of those people that turn off ipv6 "because it's too hard to make it work" (no shit - when you actively break something, it's hard to make it work). |

You've just neatly described my experience (and naivety), because I've always dropped ICMP and wondered why ipv6 never worked. In all of the articles I've read on getting ipv6 to work, this had never been explained.
