Episode 48: The Default Gateway — Directing Traffic Outward
This episode explains the role of the default gateway, which directs traffic from a local network to destinations outside its subnet. Without a properly configured gateway, devices can communicate internally but cannot reach external networks or the Internet. The exam frequently tests your ability to identify gateway settings and troubleshoot when they are missing or misconfigured.
The discussion expands with examples of how gateways work in practice. A workstation on a LAN forwards traffic for an external server to the default gateway, typically a router interface, which then determines the next hop. Troubleshooting scenarios include identifying incorrect gateway entries that block Internet access or duplicate settings causing routing conflicts. By mastering this concept, you can approach exam questions and real-world problems involving network reachability with confidence.
