摘　　要：网络地址转换技术即NAT(Network Address Translation),是为解决互联网IPv4格式中IP地址匮乏问题的一个重要技术,也是一门非常实用的技术。通过采用NAT技术,可以使用较少的互联网合法有效的IP地址,实现单位或部门内部大量私有地址的计算机上网,从而扩展了互联网的接入能力,有效地缓解了地址不足的问题,并且具有较好的安全性。本文作者在Cisco2611路由器上采用NAT技术,利用校园网分配的合法IP地址,实现了学院二级院系小型计算机网络上网,是建立部门级网站的典型应用。Network Address Translation （NAT） is not only a kind of important technology to solve the problems of the scarcity about IP addresses in IPV4 format, but it is a very practical technology as well. By using NAT technology and a few legal and available Internet IP addresses, we can make a lot of computers with private IP addresses in a unit or department browse Internet, which can expand capability to link Internet, effectively solve the problems about the scarcity of IP addresses and have better security. The authors have implemented a small campus network to link Internet by using NAT technology and computer network legal IP addresses. This is a model case to establish a web site of a branch.
