Comprehensive and Detailed 150 to 250 words of Explanation From Palo Alto Networks Network Security Analyst Knowledge:

To allow external access to an internal server while hiding the server's actual listening port, the analyst must configure Destination NAT (DNAT) with Port Translation. In this configuration, the "Original Packet" is defined with a destination of the firewall's public IP on port 443.

The "Translated Packet" is then configured to redirect that traffic to the server's internal private IP on port 8443. This allows the server to remain "cloaked" on its non-standard port, while users on the internet can connect using a standard web port. This objective is critical for policy management, as it allows for flexible network design and improves security by obscuring the internal service details from external scans.
