I’ve been using PfSense @ home dual-stack on Cox for a year or two. As far as I can tell any IPv6 problems are Cox issues.

Not all features are at parity with v4 (the captive portal doesn't support v6, for example), but the core features of stateful firewall, DHCPv6, etc seemed to work without any fuss.

They all claimed they did, but were unable to verify any successful installations. Later they told me it was on their "Roadmap" but were unable to provide an estimated year, because it was a trade secret. Starting this last year at BlackHat US, I again visited every product booth, asking if their products supported dual-stack or IPv6 only operations. Receiving only the same unsupported answers, I decided to focus on one product category. To the gurus of the NANOG community, What are your experiences with installing and managing Next Generations firewalls? Do they support IPv6 only environments? Details? Stories? If you prefer not to disparage those poor product companies, please contact me off the list.
