Network Address Translation — CompTIA Network+ (N10-009) Practice Questions
Network Address Translation is a core IP services topic on the N10-009 exam and describes the process of rewriting source or destination IP addresses as packets traverse a gateway device, typically to bridge private RFC 1918 address space and the public Internet. The exam expects candidates to distinguish between inside local, inside global, outside local, and outside global address terminology when analyzing NAT configurations. PAT, which extends NAT by also translating port numbers, is the most common deployment and is how home routers allow dozens of devices to share a single public IP. Troubleshooting scenarios often involve NAT misconfiguration as a cause of one-way communication or application failure.
