3. Configure a dynamic

IPv4/IPv6 address

mapping policy on

the IPv6 side.

• Associate an IPv6 ACL with an address pool:

natpt v6bound dynamic acl6 number

acl-number address-group address-group

[ no-pat ]

• Associate an IPv6 ACL with an interface

address:

natpt v6bound dynamic acl6 number

acl-number interface interface-type

interface-number

• Associate a NAT-PT prefix with an address

pool:

natpt v6bound dynamic prefix natpt-prefix

address-group address-group [ no-pat ]

• Associate a NAT-PT prefix with an interface

address:

natpt v6bound dynamic prefix natpt-prefix

interface interface-type interface-number

Use one of the commands.

NOTE:

• The NAT-PT prefix referenced in a natpt v6bound dynamic command must have been confi

ured with

the natpt prefix command.

• If the no-pat keyword is specified, dynamic mapping policies are used for NAT-PT. If this keyword is no

specified, the NAPT-PT mechanism is used to translate between IPv4 addresses and IPv6 addresses, and

the end IPv4 address in the address pool is used for NAPT-PT.

• For ACL configuration, see

Access Control Configuration Guide

Configuring IPv4/IPv6 address mappings on the IPv4 side

IPv4/IPv6 address mappings on the IPv4 side can be static or dynamic.

Configuring a static mapping on the IPv4 side

A static IPv4/IPv6 address mapping on the IPv4 side shows the one-to-one correspondence between an

IPv4 address and an IPv6 address.

• If the source IPv4 address in a packet sent from an IPv4 host to an IPv6 host matches a static

IPv4/IPv6 address mapping, the source IPv4 address is translated into the corresponding IPv6

address.

• If the destination IPv6 address in a packet sent from an IPv6 host to an IPv4 host matches a static

IPv4/IPv6 address mapping, the destination IPv6 address is translated into the corresponding IPv4

address.

To configure a static IPv4/IPv6 address mapping on the IPv4 side:
