NAT64
Overview
You can configure two types of NAT64 translation on
a Palo Alto Networks firewall; each one is doing a bidirectional
translation between the two IP address families:
A single IPv4 address can be used for NAT44 and NAT64; you don’t
reserve a pool of IPv4 addresses for NAT64 only.
NAT64 operates on Layer 3 interfaces, subinterfaces, and tunnel
interfaces. To use NAT64 on a Palo Alto Networks firewall for IPv6-initiated
communication, you must have a third-party
DNS64 Server or
a solution in place to separate the DNS query function from the
NAT function. The DNS64 server translates between your IPv6 host
and an IPv4 DNS server by encoding the IPv4 address it receives
from a public DNS server into an IPv6 address for the IPv6 host.
Palo Alto Networks supports the following NAT64 features:
