IPSec与NAT“争端”的研究与解决

Study of the Contradiction between IPSec and NAT and Its Solutions

本文对网络安全协议IPSec和网络地址转换NAT的工作原理和机制作一个简单的概述 ,并在此基础上指出这两种网络技术的矛盾所在。介绍了目前解决这种矛盾较好的两个方案 :RSIP和UDP ,并重点描述了后者具体实施的步骤。

This paper makes a brief review of the working principle and mechanism of IP Security Protocol (IPSec) and Network Address Translation (NAT). Then it points out where the contradiction between these two networking technologies exists. Finally, it presents two possible schemes of RSIP and UDP to solve this problem, with emphasis on the procedures of implementation of the latter.
