This video demonstrates the syntax to configure a Static NAT on a Cisco Router. We then send packets through the device to show you the packets before and after translation to show you exactly what is modified with a Static NAT. We'll also look at the command `show ip nat translations` to verify the NAT operation through a Cisco router.

This is a free lesson from my course on Network Address Translation on Udemy. The course runs $30 normally, or less through the various Udemy Sales:

====
The full course has two modules:

The first module will teach you Everything there is to know about Network Address Translation: Why it exists, How it it works, What happens to packets as they get translated. This module will explain every type of translation: Static NAT, Static PAT, Dynamic PAT, and Dynamic NAT. You'll learn about each of these in a way that is completely vendor agnostic -- the concepts you learn here will apply to any vendor and any platform. You'll then learn how these four types of translations are used in Policy NAT and Twice NAT.

The second module will teach you how to Configure and Verify each type of address translation discussed in Module 1. If you configure or troubleshoot NAT on a Cisco Router, this is the module for you! We'll methodically take you through the the syntax for each type of NAT and show you various show commands that let you validate NAT's operation.

The lab topology will show and prove every NAT concept from Module 1, as we show you a packet capture before it arrives on the NAT router, and after it leaves the NAT router -- showing you exactly what is changed and in what situations.

This course is the last resource you will ever have to study to become a subject matter expert (SME) on NAT on a Cisco Router.
