Often, the router will not allow you to remove or change the NAT configuration
because dynamic translations have been created. When this occurs, you need to
remove the inside or outside designation from an interface so translations cannot
be created. When this happens, all NAT translations stop on the router. Then
you can clear the translations and reconfigure or remove the NAT configuration.
