Connecting to the Internet using just a static route is one of the simplest—but most misunderstood—topics in networking interviews.

In this video, I explain exactly how to connect your LAN to the Internet using:

A default static route (0.0.0.0/0)
NAT / PAT to convert private IPs into public IPs
A basic home/office-style topology
Step-by-step packet flow from PC → Router → ISP → Internet

You’ll learn:

✔ Why we need a default route
✔ What 0.0.0.0 0.0.0.0 actually means
✔ How the router sends unknown traffic to the ISP
✔ Why NAT is required for private IP networks
✔ PAT overload configuration basics
✔ How packets reach 8.8.8.8 or google.com
✔ Simple real-world examples

This topic appears very often in CCNA, CCNP, and job interviews.
If you understand this clearly, many other routing concepts become much easier.
