Configuring a NAT-PT prefix
Follow these guidelines when you configure a NAT-PT prefix:
• The NAT-PT prefix must be different from the IPv6 address prefix of a local interface. Otherwise,
incoming packets matching the prefix get lost due to NAT-PT translation.
• To delete a NAT-PT prefix that has been referenced by using the natpt v4bound dynamic or natpt
v6bound dynamic command, you must cancel the referenced configuration first.

Configuring IPv4/IPv6 address mappings on the
IPv6 side
IPv4/IPv6 address mappings on the IPv6 side can be static or dynamic.
Configuring a static mapping on the IPv6 side
A static mapping on the IPv6 side shows the one-to-one correspondence between an IPv4 address and
an IPv6 address:
• If the source IPv6 address in a packet sent from an IPv6 host to an IPv4 host matches the static
mapping, the source IPv6 address is translated into the corresponding IPv4 address.
• If the destination IPv4 address in a packet sent from an IPv4 host to an IPv6 host matches the static
mapping, the destination IPv4 address is translated into the corresponding IPv6 address.
