The Technology of NAT and the Research of its Traverse Solutions

The technology of NAT has been widely used in many domains, but the problem, how to solve the problem of NAT traverse, must be adverted in the application. This paper introduces the technology of NAT and the problem of NAT traverse, and shows the problem that would be met in the application for NAT traverse with a example, and ana- lyzes the solutions and its limitation which can be used to realize NAT traverse at present in the last.
