To do… Use the command… Remarks
Associate an IPv6 ACL with an address
pool:
If the source IPv6 address of an IPv6
packet matches the specified IPv6 ACL, the
source IPv6 address will be translated into
an IPv4 address of the specified address
pool.

Associate an IPv6 ACL with an interface
address:
If the source IPv6 address of an IPv6
packet matches the specified IPv6 ACL, the
source IPv6 address will be translated into
the IPv4 address of the specified interface.

Associate a NAT-PT prefix with an address
pool:
If the destination IPv6 address of an IPv6
packet matches the specified NAT-PT
prefix, the source IPv6 address will be
translated into an IPv4 address of the
specified address pool.

Associate a NAT-PT prefix with an

If the destination IPv6 address of an IPv6
packet matches the specified NAT-PT
prefix, the source IPv6 address will be
translated into the IPv4 address of the
specified interface.

Configure any of the four
types of dynamic mappings.
NOTE:
•
The NAT-PT prefix referenced in a natpt v6bound dynamic command must have been configured with
the natpt prefix command.
• If the no-pat keyword is specified, dynamic mappings are used for NAT-PT. If this keyword is not
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 the ACL configuration, see ACL configuration in the Firewall Web Configuration Manual.
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.
