基于连线跟踪的源地址转换技术研究与应用

Research and Application of SNAT Technology Based on Connection Tracking

面对日益严重的公用IP地址短缺问题,本文分析了共享静态IP上网和共享动态IP上网两种方式,并且针对两种共享IP上网各自所拥有的特点,研究了Linux下两种源地址转换技术,并且配合连线跟踪机制,设计了两种源地址转换方案。

Faced with an increasingly serious shortage of public IP addresses, this paper analyzed two ways about sharing static IP and dynamic IP to access to the network. For two ways of sharing their IP have characteristics, this paper researched two ways about sNAT, teclinology based： on Linux, with the connection tracking mechanism, design the two source network address translation program.
