What command is used to display all static translations configured for NAT or PAT?

The command used to display all static translations configured for Network Address Translation (NAT) or Port Address Translation (PAT) is "show ip nat translations." This command provides a comprehensive view of the active NAT translations, including the static entries, which are crucial for understanding how the internal IP addresses are mapped to external addresses.

When you run this command, it lists all current translations, showing both inside local addresses (IP addresses assigned to hosts in the internal network) and corresponding inside global addresses (public IP addresses used on the external network). This visibility is essential for troubleshooting and ensuring that NAT is configured correctly.

The other commands serve different purposes. For example, "show ip nat statistics" focuses on overall NAT operation statistics, including the number of translations and the number of active translations, but doesn’t provide a detailed list of the actual translations. "Show ip nat configuration" is not a standard command and, while useful commands may exist for NAT configuration, they would not provide translation information. Similarly, "show ip nat mappings" is not a recognized command in Cisco IOS for NAT. Therefore, "show ip nat translations" is the most effective method for retrieving and verifying the current NAT and PAT configurations.
