Task Remarks
Enabling NAT-PT Required.
Configuring a NAT-PT prefix Required.
Configuring IPv4/IPv6 address mappings on the IPv6
side
Required.
Configuring a static mapping on the IPv4 side
Optional.
If no static IPv4/IPv6 address mapping is configured,
the lowest 32 bits of the destination IPv6 address is
used as the translated destination IPv4 address.

NAT-PT configuration task list on the IPv4 side
Complete the following tasks to configure NAT-PT to allow active access from an IPv4 host to an IPv6 host:
Task Remarks
Enabling NAT-PT Required.
Configuring a NAT-PT prefix Required.
Configuring IPv4/IPv6 address mappings on the IPv4
side
Optional.
If no IPv4/IPv6 address mapping is configured, the
source IPv4 address added with the first configured
NAT-PT prefix is used as the translated source IPv6
address.

Configuring NAT-PT
Configuration prerequisites
Before implementing NAT-PT, you need to:
• Enable IPv6 on the firewall. For more information, see Network Management Configuration Guide.
• Configure an IPv4 or IPv6 address as required on the interface to be enabled with NAT-PT.
