Episode 43: NAT — Hiding Networks Behind a Single IP
This episode introduces Network Address Translation (NAT), a process that allows multiple internal devices to share a single public IP address. It explains the core function of NAT in conserving IPv4 addresses and providing a layer of obfuscation between private networks and the Internet. NAT is a frequent exam topic because it connects concepts of addressing, routing, and security.
The discussion continues with practical examples, such as how NAT translates private source addresses to a public address when accessing external websites. It also examines common troubleshooting issues, such as port forwarding misconfigurations or NAT devices interfering with peer-to-peer applications. You’ll learn to recognize NAT scenarios in exam questions and apply its principles in professional contexts where address conservation and external connectivity are required.
