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.
