ah right - wasn't clear from context.

Look, google is your friend.  Here are some search queries that you should
look into before continuing:

http://www.google.com/search?q=iptables+ipv6+howto
http://www.google.com/search?q=iptables+logging

The best approach here is to open up all rules on the packet filter and
enable logging.  Then turn on new rules one by one and see how things
break.  As Tore mentioned separately, you will need to enable icmp6 because
this does the work of IPv4's arp.
