Can I log NATing events e.g. what private IP was translated into real IP for any destination and port. In fact we are running both NAT and PAT on our 7600 router.

Hi,


You can watch the translation using "show ip nat translations", further more the logging of NAT translations can be enabled using the "ip nat log translations syslog" command.


Syslog Analysis lets you centrally log and track system error messages, exceptions, and other information (such as NAT translations). You can use the logged error message data to analyze router and network performance. You can customize Syslog Analysis to produce the information and message reports important to your operation.
