           Summary: ip6tables maks auto configuration packages as INVALID
           Product: iptables
           Version: unspecified
          Platform: i386
        OS/Version: Debian GNU/Linux
            Status: NEW
          Severity: blocker
          Priority: P1
         Component: ip6tables
        AssignedTo: laforge at netfilter.org
        ReportedBy: Die_Obstfliege at gmx.de


I use $IPTABLES -A INPUT -j DROP -m state --state INVALID in my ip6tables
config.
When my client tries to resolv an ipv6 address the firewall marks the packages
as INVALID and drops them. ( so far Router Solicitations, Neighbor
Solicitations and Neighbor Advertisements and maybe other packages too )

ip6tables-INVALID: IN=eth0 OUT= MAC=33:33:00:00:00:02:00:13:77:ae:f2:1f:86:dd

without this check the client gets the IPv6 immediately.
