Network Address Translation （NAT） is an important and difficult content of computer network, network technologies, network management, and other related courses of network engineering. This paper introduced the background and principles of the network address translation, and designed the experiment based on protocol analysis and NAT session information. By analyzing NAT ses- sion information and the results of protocol analysis, the experiment shows in detail the principle of 3 types network address translations, static, dynamic, and port-level NAT. This experiment does not only allow students to understand the principles of NAT deeply, but also enhances their self-study abilities for various protocols, improves the teaching quality of network experiment.
