Configuring the NAT-PT
Session Timeout Time
for Different Protocol
Packets
To do...
Configure a NAT-PT address pool and
define a dynamic IPv6-to-IPv4 mapping rule
as follows:
If the source IPv6 address of an IPv6 packet
matches the specified IPv6 ACL rule, the
source IPv6 address will be translated into
an IPv4 address of the specified address
pool.
Define a dynamic IPv6-to-IPv4 mapping
rule as follows:
If the source IPv6 address of an IPv6 packet
matches the specified IPv6 ACL rule, the
source IPv6 address will be translated into
an IPv4 address of the specified interface.
Configure a NAT-PT address pool and
define a dynamic IPv6-to-IPv4 mapping rule
as follows:
If the destination IPv6 address of an IPv6
packet contains a NAT-PT prefix, the source
IPv6 address will be translated into an IPv4
address of the specified address pool.
Define a dynamic IPv6-to-IPv4 mapping
rule as follows:
If the destination IPv6 address of an IPv6
packet contains the NAT-PT prefix, the
source IPv6 address will be translated into
an IPv4 address of the specified interface.
The natpt-prefix argument specified in the natpt v6bound dynamic prefix
■
natpt-prefix interface interface-type interface-number command must have
been configured with the natpt prefix command.

You can set the timeout time for NAT-PT sessions of different protocol packets
according to the actual conditions. NAT-PT will stop after the NAT-PT session of a
specified protocol packet times out.
Follow these steps to configure NAT-PT session timeout time for different protocol
packets:
