网络防火墙远程控制及关键技术应用研究

On the Application of Key Technologies in the Remote Control of Net Firewall

研究了基于远程控制的服务器与客户端的Socket通信和网络防火墙中的远程控制端的算法设计。在Linux操作系统平台上将防火墙的包过滤、网络地址转换、MAC和IP地址绑定等各项功能进行整合;通过基于C/S模型的Socket通信程序设计,成功地实现了防火墙的远程控制,解决了实验室IP地址冲突以及防火墙策略设置复杂的问题。

This paper discusses the socket communication between server and client port, and design of arithmetic about the remote control of firewall. The functions of net firewall data packages filter, NAT, MAC and IP binding based on Linux OS are integrated, and throught the program design of Socket communication based on C/S model, the remote control of firewall is successfully realized. The problems of the scare of IP address and the complex tactics of setting firewall in lab network are solved.
