   Pekka Savola created the original IPv6 Security Overview document,
   which contained suggestions for ICMPv6 filter setups.  This
   information has been incorporated into this document.  He has also
   provided important comments.  Some analysis of the classification of
   ICMPv6 messages and the term 'any-to-end' were used by Jari Arkko in
   a document relating to ICMPv6 and IKE.

   The Netfilter configuration script in Appendix B was contributed by
   Suresh Krishnan.
