Usage guidelines
Enable NAT logging before you enable NAT444 user logging for port block withdrawal.
For static NAT444, the NAT444 gateway generates a user log when all connections from a private IP
address are disconnected.
For dynamic NAT444, the NAT444 gateway generates a user log when all the following conditions are
met:
• All connections from a private IP address are disconnected.
• The port blocks (including the extended ones) assigned to the private IP address are withdrawn.
• The corresponding mapping entry is deleted.
