	Cool!  That's good to know.  Now I can stop digging through kernel and
iptables sources.  :-)

	I trust then that the default IPv6 firewall logic/rules for FC6 will be
modified to avoid this behavior until such time as it becomes fully
functional?  Right now it's seriously broken OOB (out of the box) and
leaves the entire IPv6 networking non-functional.
