icmpv6 firewall rules

[Ernie Luzar]

Running ipfilter and see default blocked icmpv6 packets in the log file.
Added this rule to the ipf.rules file
pass in quick on re0 proto icmpv6 all

When I load that rules file I get error on that ipv6 rule.

Can not find any info on firewall rules for ipv6 for ipfw, pf and 
ipfilter concerning icmpv6 routeradvert and neighborsolicit.

Any help would be greatly appreciated.
