Is it possible to build a configuration with both static and dynamic NAT translations?
A. Yes. However, the same IP address cannot be used for the NAT static configuration or in the pool for NAT dynamic configuration. All the public IP addresses need to be unique. Note that the global addresses used in static translations are not automatically excluded with dynamic pools containing those same global addresses. Dynamic pools must be created to exclude addresses assigned by static entries. For more information, refer to Configuring Static and Dynamic NAT Simultaneously.
