IPSec和NAT之间的不兼容性问题解决方案的探讨

因特网安全协议IPSec（Intemet Protocol Securicy）和网络地址转换NAT（Network Address Translation）是目前流行的网络技术。但是由于技术上的冲突，当它们一起工作时就出现许多不兼容性方面的问题。本文首先分别介绍了IpSec和NAT技术及其应用，然后分析了IPSec和NAT之间的不兼容性产生的原因以及解决它们之间不兼容性必须满足的条件，最后讨论了目前存在的几种解决方案并指出解决方案中的优点和不足，从而更有利于以后对IPSec和NAT之间的兼容性问题的研究，更有利于互联网的发展。

The Discussion of the Solutions of the Non-Compatibility Problem between IPSec and NAT

IPSec and NAT are two important protocols which are widely used in network transportion. But some compatibility problems will happen when they work together. This paper Firstly introduce the IPSec and NAT technology and their application respectively,then analyse the cause and the requirement of the solution between IPSec and NAT.Finaly it discuss some present solutions and point out the advantages and the disadvantages of the solutions,It is in favor of the research for the development of network in the future.
