Why are you using NAT with IPv6? There is very little reason pros for
using IPv6 with NAT, and many cons. Afterall, NAT is just a hack for
IPv4 to prevent address exhaustion. IIRC, ISPs are not to give out
single IP addresses, but rather /64 allocations.
Anyone care to correct me on this?
"NAT-PT (Network Address Translation - Protocol Translation) is an
IETF RFC specification for an IPv4 to IPv6 protocol translator." -
In answer to your specific question, some people also like DNAT for
security reasons because it makes it harder to connect to internal
hosts from the Internet than having routable IP addresses with no NAT,
or static NAT. But I'm sure that's not what Philip's main aim is here.
