HAPTER ONFIGURATION
Combination 4: Combination of a NAT-PT prefix with an interface address
■
If the destination IPv6 address of a packet contains a NAT-PT prefix, the source IPv6
address will be translated into an IPv4 address of the specified interface.
If combination 1 or combination 3 is used to configure dynamic mappings for IPv6
hosts accessing IPv4 hosts, you need to configure a NAT-PT address pool.
A NAT-PT address pool is a group of successive IPv4 addresses and is used to
translate an IPv6 packet into an IPv4 packet dynamically. When an IPv6 packet is
sent from an IPv6 network to an IPv4 network, if the dynamic NAT-PT of
combination 1 or 3 is set, the NAT-PT device will select an IPv4 address from the
NAT-PT address pool as the source IPv4 address of the IPv6 packet.
Follow these steps to configure mappings for IPv6 hosts accessing IPv4 hosts:
