I should have added that most of the rest of configuring
IPv6 is getting a IPv6 feed and configuring the interfaces.
How you do that is often OS specific.

If your upstream does not provide IPv6 natively you will
need to move your IPv6 packets using IPv4. I would recommend
getting a tunnel to do the though there are other mechanisms
(6to4 and Terado).
