基于IPSEC和NAT技术的UDP封装方法

UDP Package Method Based on the IPSEC and NAT Technology

网络地址转换技术(NAT)与IPSec在因特网上都是得到广泛应用的技术,但是它们之间却是不兼容的。文章首先介绍了NAT和IPSec两种协议的基本原理,分析了两者的不兼容性,然后讨论了解决该问题必须满足的要求,最后给出了利用UDP封装法实现NAT透明穿透的解决方案。

NAT and IPSEC are the technology widely used on the Intemet, but between them it is not compatible. The article first introduced the basic principles of the NAT and IPSEC agreements, analysed the incompatibility between the two, discussed the requirements that must be met to solve the problem and finally presented the method to realize the solution of NAT transparent penetration.
