【摘要】 NAT和IPSEC技术在当前的Internet中得到了广泛的应用,但两者在协议设计时存在的兼容性问题成为了阻碍这两种技术得到进一步应用的关键问题。简要介绍了NAT和IPSEC协议的原理,详细分析了两种协议在兼容性上存在的问题,研究了现有解决此问题的一些技术以及它们各自的优缺点,最后设计并初步实现了一种基于Linux中Netfilter网络框架的支持NAT和IPSEC协同工作的软件模型。更多还原

【Abstract】 The incompatibility between NAT and IP security protocol has been a major barrier to their application seriously,although they are popular techniques in Internet today.NAT and IP security protocol were introduced briefly.Then the existing incompatibility problems between them were analyzed in detail.After researching some known solutions to the barrier,a model supporting interactions between NAT and IP Security based on Linux Netfilter framework was designed and basically realized.更多还原
