Paper Abstract

This paper analyzed the type of work principles of the NAT server, and by using UDP Hole Punching and port speculation technology, a program was designed to penetrate the NAT server and direct communication among the intranet users was achieved. This paper also evaluated the communications among users in various types of NAT servers, and it showed a success rate of 95%. By analyzing the principles and setting rules of firewall, together with the application of HTTP tunnel, the designed procedures have penetrated the firewall to visite the user without lowering the security level of the system. The eventual establishment of communication modules facilitated the direct peer-to-peer GIS data transmission.
