Configuring NAT-PT 685n ■ The natpt-prefix argument specified in the natpt v6bound dynamic prefixnatpt-prefix interface interface-type interface-number command must havebeen configured with the natpt prefix command.■ For ACL configuration, refer to “Configuring ACLs” on page 1881.Configuring the NAT-PTSession Timeout Timefor Different ProtocolPacketsYou can set the timeout time for NAT-PT sessions of different protocol packetsaccording to the actual conditions. NAT-PT will stop after the NAT-PT session of aspecified protocol packet times out.Follow these steps to configure NAT-PT session timeout time for different protocolpackets:To do... Use the command...
