基于Linux的网桥和NAT网关集成的实现

Implementation of Integration of Bridge and NAT Gateway Based on Linux

提出了一种集成网桥和NAT网关的局域网络的实现方法 ,利用现有资源较好地解决了IP地址分配和主机互联的问题 ,提高了网络的效率 ,防止了Intranet内部通信的信息泄漏 ,增强了网络的安全性 ,使性能普通的网络设备得到了充分的利用 。

This paper presents an approach to build LAN of integration of Bridge and NAT Gateway. This approaches can solve the problems of IP addresses distribution and hosts interlinkage through the full use of present sources, improve net efficiency, prevent information leakage and enhance security in Intranet, and use the ordinary net equipment fully. This method also illustrates how to use Linux, the excellent free OS to establish Integration of Bridge and NAT Gateway.
