Which command will display which router interfaces are configured as NAT inside interfaces?
- show ip nat interfaces
- show ip nat statistics
- show ip nat translations
- show ip interface
Explanation: The show ip nat statistics command is the correct tool to verify which router interfaces have been designated for NAT operations.
When this command is executed, the output includes specific sections for:
- Outside interfaces: Lists all interfaces configured with the ip nat outside command.
- Inside interfaces: Explicitly lists all interfaces configured with the ip nat inside command.
While other commands like show ip nat translations display the active mapping table, they do not provide a summary of the interface roles themselves. The show ip nat statistics command is used specifically in the source material to verify that previous configuration steps were successful and that the expected interfaces are participating in the NAT process.
