Match each Network Address Translation (NAT) implementation concept on the left with its corresponding operational description and traffic mapping behavior on the right.
- Static NATMaps a single private IP address to a dedicated public IP address permanently, supporting unsolicited inbound connections to internal DMZ servers.
- Dynamic NATMaps private IP addresses to an available pool of public IP addresses on a first-come, first-served basis without modifying Layer 4 transport ports.
- Port Address Translation (PAT)Translates multiple private IP addresses to a single public IP address by tracking unique Layer 4 source port numbers for each session state.
- Static PAT (Port Forwarding)Maps a specific public IP address and destination transport port pair to a specific internal private IP address and service port.
Cevap
Static NAT matches the permanent one-to-one IP mapping for DMZ servers. Dynamic NAT matches the pool-based mapping without port alteration. Port Address Translation (PAT) matches many-to-one translation using Layer 4 source ports. Static PAT matches destination port redirection to an internal host and service port.
Each NAT type is accurately paired with its technical execution model: Static NAT provides permanent 1-to-1 IP mapping for unsolicited server access; Dynamic NAT allocates 1-to-1 public IPs dynamically from a pool without port alteration; PAT multiplexes many private IPs to one public IP using Layer 4 source ports; and Static PAT maps targeted public incoming transport ports directly to internal hosts.
