NPTv6
IPv6-to-IPv6 Network Prefix Translation (NPTv6) performs
a stateless, static translation of one IPv6 prefix to another IPv6
prefix (port numbers are not changed). There are four primary benefits
of NPTv6:
You can prevent the asymmetrical routing problems that
result from Provider Independent addresses being advertised from
multiple datacenters.
NPTv6 allows more specific routes to be advertised so that
return traffic arrives at the same firewall that transmitted the
traffic.
Private and public addresses are independent; you can change
one without affecting the other.
This topic builds on a basic understanding of NAT. You should
be sure you are familiar with
NAT concepts
before configuring NPTv6.
