I'm curious... how do you actually use IPv6? I'm guessing, IPv6 will be for public IP, and IPv4 will be for internal NAT. No?
Dual stack. You use both. If dns returns an ipv6 for a site (like google, facebook, and many other major sites) then you connect using ipv6, otherwise if dns returns only ipv4 you connect using ipv4. So outbound your route would do NAT for ipv4 connections, and not do NAT for ipv6 connections. At least usually. I have a plugin on firefox that shows if the conenction is all ipv4, all ipv6, or a mix (and what the primary connection is using in that case). -- Len Sorensen
