Furthermore, the idea of connecting the above networks arouses great interest of network companies and network researchers. The major concerns for connecting these networks are security and private. Accordingly, the Virtual Personal Network (VPN)[1] was developed. The implementations of VPN router were built on the top of a costly hardware platform, which is unaffordable for regular household users and small businesses. In this study, we build the VPN on the top of the Linux Router Project (LRP)[2], a more economical software oriented design. Both IPSec[3] and CIPE[18] of VPN are implemented. Comparisons of two implementations are made through evaluating real network packet and using the network traffic-analyzing tool. It shows these implementations have accomplished a safe point-to-point communication and bi-tunnel communications through VPN tunneling. A preliminary investigation on the capability and efficiency of the above implementations, and the performance where integrated with firewalls are provided. In all, the implementations provide us the advantages of flexibility, economy, and easy maintenance by little sacrifice of transmission speeds.
