Configuring an Internal Server in a NAT64 Instance
The internal server function can be configured on a private network so that IPv4 users can access an IPv6 server through a NAT64 device.
Usage Scenario
NAT64 allows IPv6 users to initiate access to IPv4 services. IPv4 users, however, cannot access IPv6 users.
To address this problem, the internal server function can be configured on the private network where a NAT64 device resides. The internal server function in a NAT64 instance implements reverse translation from IPv4 addresses to IPv6 addresses based on statically configured mapping between IPv4 addresses and pairs of IPv6 addresses and prefixes.
Procedure
- Run system-view
The system view is displayed.
- Run nat64 instance instance-name [ id id ]
The NAT64 instance view is displayed.
- Run nat64 server global global-address [ vpn-instance vpn-instance-name ] inside host-address prefix-id prefix-id
The internal server is configured in the NAT64 instance.
The IP address of the internal server must be different from the IP address of a DHCP server. Otherwise, a message about the address conflict is displayed.
- Run commit
The configuration is committed.
