几种 IP 地址共享方式的分析与应用

The Analysis and Application of Several Methods of IP Address Sharing

对ＴＣＰ／ＩＰ网上ＩＰ地址共享的几种常见方式（代理ＡＲＰ、ＩＰ伪装和代理服务器）在网络协议、适用范围、对客户端及服务器端程序的要求、内网可访问性、对防火墙的支持等方面的不同特点进行了分析和比较．给出了在Ｌｉｎｕｘ和Ｗｉｎｄｏｗｓ操作系统下上述几种技术的具体应用实例．

Several methods of IP address sharing over TCP/IP network are analyzed and compared in the paper, including Proxy ARP, IP Masquerade and Proxy Server. There are some relevant problems about these methods, such as the layer of network protocol, the scope to use these technologies, the requirement for client and server programs, the accessibility of private network, the supporting for firewall etc., are also discussed. In addition, the variant schemes of implementing these methods on Windows and Linux operation system, and the installation, configuration and usage of relevant software are also introduced in the paper.
