Parameter acl-number: IPv4 access control list (ACL) number, in the range of 2000 to 2999. natpt-prefix: NAT-PT prefix, 96 bits in length.

Description Use the natpt v4bound dynamic command to configure a dynamic IPv4-to-IPv6 mapping.

Use the undo natpt v4bound dynamic command to remove the dynamic mapping.

For a packet from an IPv4 host to an IPv6 host, if the source IPv4 address complies with the specified ACL rule, a NAT-PT prefix will be added to translate the source IPv4 address into an IPv6 address.

c CAUTION: The natpt-prefix argument in the natpt v4bound dynamic command must be specified by the natpt prefix command in advance.

Example # Use ACL 2000 to identify the source address of an IPv4 packet and add the NAT-PT prefix 2001:: to translate the source address into an IPv6 address.

Parameter ipv4-address:Source IPv4 address to be mapped.

ipv6-address: IPv6 address to which the source IPv4 address is mapped.

v6server: Specifies to implement the protocol-specific port mapping at the time of address mapping.
