NAT-PT configuration task list
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 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.
Setting the ToS field after NAT-PT translation Optional.
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 IPv4/IPv6 address mappings on the IPv4
side
Required.
Complete either task.
Configuring static NAPT-PT mappings of IPv6 servers
Setting the traffic class field after NAT-PT translation Optional.
Configuration prerequisites
Before you implement NAT-PT, complete the following tasks:
1. Enable IPv6 on the device. For more information, see "Configuring IPv6 basics."
2. Configure an IPv4 or IPv6 address as required on the interface to be enabled with NAT-PT.
Enabling NAT-PT
After NAT-PT is enabled on both the IPv4 network interface and the IPv6 network interface, the device
can implement translation between IPv4 and IPv6 addresses.
To enable NAT-PT:
