Description

When TCPIP v4 was created, security and address preservation were not concerns like they are today. Fortunately, we now have network address translation to assist. In this course, Protocol Deep Dive: Network Address Translation (NAT), you will gain foundational knowledge of the potential security risks and rewards of using network address translation. First, you will learn how most experienced network administrators have worked with network address translation using Port Address Translation or linking IPs. Next, you will discover some other types of NAT also available. Finally, you will explore the interpretations of NAT by companies like Cisco that change the definition of the RFCs for NAT. When you are finished with this course, you will have the skills and knowledge of network address translation needed to set up NAT on your network layer device and to troubleshoot NAT issues.

Course Overview
Hello, my name is Robert McMillen. When TCP/IP version 4 was created, security and address preservation were not a concern like they are today. A protocol needed to be developed to deal with both very important issues. Fortunately, we now have network address translation to assist. In this course, Protocol Deep Dive into Network Address Translation, you'll learn how NAT works and how it has changed over the years to accommodate new application requirements and resolve security issues. First, you'll learn the history of NAT and gain the foundational knowledge needed to understand how NAT works and understand what it provides us as network administrators. Next, you'll learn the skills to use firewalls, routers, and servers to view NAT traffic so you can troubleshoot NAT issues as they arise. Finally, you'll learn about security issues to watch for with network address translation and how to mitigate problems and compliance concerns. When you're finished with this course, you'll have all the skills and tools needed to set up and configure NAT, as well as troubleshoot problems that may occur. I hope you'll join me in learning these important skills for network administrators and sys admins in my course, Protocol Deep Dive into Network Address Translation.
