How to view the NAT Translation Table on a Cisco Router

To view the NAT translation table on a Cisco router to ensure it is not overloaded, the command you want to use is:

"show ip nat translation"

Run this command from enable mode.  This command is useful especially when wanting to see if your  NAT tables are getting slammed by a large number of web connections from potential miscellaneous software on your network.

Another command which is useful when identifying if your router is overloaded from  NAT is to check the memory.  This can be viewed with the "show mem" command.
