While I don't really disagree with that statement, I'm not entirely sure
what CPE firewalls and home devices have to do with enterprise deployments,
the topic I was discussing. We've been actively working this for the past
three years now and have yet to encounter an IPv6 specific enterprise risk
for which no appropriate mitigation exists. That's why I called out the
assertion that security weaknesses in IPv6 were *preventing* enterprise
deployments as FUD. And until someone specifically names some major
unmitigated IPv6-only security weakness blocking enterprise deployment
instead of vague hand-waving or lists of security risks (as opposed to
weaknesses) with well-defined mitigations, I'll stand by that statement.
