摘 要: 构建于公共网络之上的虚拟专用网既可以实现安全、快捷传递信息的需求,又可以节省大量的开支。本文基于Linux系统使用iptables建立网络地址翻译(net address translation,NAT)对用户的访问进行有效的控制,运用Apache建立具有FREERAIDUS认证系统的Web服务,并在此基础上运用PHP语言和数据库系统MYSQL设计了虚拟专用网(virtual private network,VPN)用户的远程接入系统,实现了校外用户对校内图书馆的远程访问及信息分流的功能。本远程接入系统方案不仅适用于校外用户对校内图书馆的访问,而且适用于移动办公用户对本单位内网的安全访问。
关 键 词: 计算机应用;虚拟专用网;iptables;网络地址翻译;远程认证拨号用户服务;隧道技术

Abstract: The virtual private network constructed on the public network can not only realize the demand for safe and fast transmission of information, but also save the massive expenditures. This paper uses iptables based on the Linux system to suggest that using net address translation(NAT) to control the user’s visit effectively. It uses Apache to establish a FREERAIDUS certification system for Web services, and on the basis of this, uses popular Internet language PHP and database system MYSQL to design VPN users’ remote access system, which realizes the function of remote access to library and information streaming. The VPN remote access system solutions not only enable the users outside to access to the school library, but also make users of mobile office to access to their units’security network.
Key words: computer application; virtual private network; iptables; network address translation; remote authentication dial in user service(RADIUS); tunneling
