基于IPSec的虚拟专用网技术及其实现

VPN Technology based on IPSec and its Realization

随着网络应用的普及,网络安全问题日益突出。IPSec在IP网络通信中提供对应用程序透明的加密服务,利用IPSec构建安全VPN已成为一种趋势。文章介绍了IPSec的基本术语,给出了Linux和Windows2000平台下在两网关之间构建基于IPSec的VPN的配置方法。

With popularization of network application, the network safety has been becoming apparent. IPSec provides the transparent encryption service for the applications on the IP network communication, therefore, it is very natural to employ it in the field of VPN. This paper introduces some of the basic terminologies of IPSec, and then describes the method of VPN configuration based on IPSec between two gateways which use Linux or Windows 2000.
