[c-nsp] v6 NAT-PT Support

[Mack McBride]

You need DNS64 as well as NAT64.
NAT-PT is just NAT64 without additional support for FTP and SIP and such.

Dear All,

While doing a v6 NAT-PT test, I'm able to access v6 web but unable to browse
the v4 Internet. For sure some config issue. Can anyone take a peak or
suggest any alternative for THIS platform?
