网络地址转换在Intranet中的应用

Application of Network Address Translator in Intranet

讨论Intranet专用地址和网络地址转换技术的机制,给出用路由器和Windows2000软件配置实现网络地址转换的方法,分析NAT技术用于Intranet安全的特点,证明NAT对各种网络攻击方式有独到的防护能力,给出NAT安全模型和实现结构设计,并对实现结构的6个模块功能进行了讨论。

This paper discusses the scheme of Intranet special network address and network address translator in Intranet. Implementation of network address translator by router and Windows 2000 software configuration is given. The paper also analyzes the characteristics of NAT application in Intranet security,and presents the ability to protect network to be attacked. NAT security model and implementation of structure design are given and structure implementation of six module functions is discussed.
