Practical Networking's video: NAT Terminology: Static NAT Static PAT Dynamic PAT Dynamic NAT -- NAT Operation and Concepts

This video answers these questions about NAT: * What do the words NAT vs PAT mean? * What do the words Static vs Dynamic mean? Upon answering those questions, you'll be able to understand what each of these Network Address Translation methods do: Static NAT, Static PAT, Dynamic PAT, Dynamic NAT. This is a free lesson from my course on Network Address Translation on Udemy. The course runs $30 normally, to get it for $12.99, use this link: https://www.udemy.com/course/network-address-translation-cisco-routers/?couponCode=E5E6423B43996E82EE41 If this link's coupon is expired, check this page for the most up to date discounted referral links: https://www.practicalnetworking.net/classes/ (or pracnet.net/classes for short) ==== 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.
