摘　　要：随着互联网的发展,越来越多的网络服务提供商需要客户固定设备的IP信息,致使用户更换使用场所时需重新设置而造成不便。提出了基于网络地址转换技术的网口即插即用服务,该技术利用Linux系统平台中IPTABLES等功能进行源地址转换及目的地址转换。通过测试,用户可以在不更改用户PC任何TCP/IP协议配置的情况下接入因特网进行网络聊天、上网浏览等一些基本网络操作,解决了用户因IP地址设置不正确而无法接入因特网的问题。With the development of the Internet,more and more internet service providers need customers＇ IP information of fixed equipment,which causes the inconvenience that users have to reset the IP information when they changes place.Therefore,a realization of plug-and-play service is proposed based on network address translation technology,which uses IPTABLES in Linux system to achieve source address translation and destination address translation.The test shows that users can access to the internet for chatting,browsing and some basic network operations without changing any TCP/IP protocol configuration in the user＇s PC,which effectively soloves the problem that user can＇t access to the internet due to the incorrect settings of IP address.

关 键 词：网络地址转换 即插即用 IPTABLES
