Abstract: Practical experiment has an important assistant effect on theory teaching. It is necessary to study thoroughly methods of practical experiment because information security is a new specialty. Considering sharing with basic specialty experiment equipment for fee is restricted, it is difficult to ensure experiment having scientific, advanced and practicable in network laboratory. In this paper, how to develop VPN experiment in basic network laboratory is introduced. Students of security specialty should do VPN experiment as VPN is a typical security technique which can ensure data transmission security by Internet.
