Problem Statement
IPv4 and IPv6 devices cannot communicate directly due to differing addressing and
data transmission protocols. This incompatibility complicates network operations and
hinders the full adoption of IPv6.
Solution: NAT for Protocol Translation
Prisma SD-WAN uses NAT for protocol translation. This feature allows
devices in different IP address families to communicate with each other. It works by
translating packet headers and addresses.
Prerequisites for IPv6 NAT Support on ION
To use NAT on your Prisma SD-WAN ION device, ensure the following
requirements are met:
- Prisma SD-WAN: A valid Prisma SD-WAN
license is required.
- ION Device Version: The device must run version 6.4.2 or higher.
- NAT-PT Gateway (for NAT64):
- A NAT-PT Gateway must be configured in the network, positioned before
the Internet Gateway.
- The service provider needs to support the well-known prefix (WKP) block
64:ff9b.
Without the NAT-PT (NAT64) Gateway support,
NAT64 use cases do not function. For more information, see
NAT 64.
- DNS64 (for NAT46):
- DNS64 must be configured to support NAT46 use cases.
- The service provider needs to support the well-known prefix (WKP) block
64:ff9b.
Without DNS64
support, NAT46 use cases do not function.
