Explanation

PAT (Port Address Translation), also called port forwarding or NAPT, allows multiple internal servers to be reached through a single public IP address by mapping specific external port numbers to specific internal hosts. For example: external port 22 → server1 (SSH), external port 80 → server2 (HTTP), external port 21 → server3 (FTP). Standard NAT maps one public IP to one private IP and cannot differentiate between multiple internal servers on the same public IP. A DMZ is a network segment, not a translation mechanism. Stateful Packet Inspection is a firewall technique. PAT is the correct mechanism for multiplexing multiple internal servers behind a single public IP using port-based routing.
