复杂网络NAT综合应用及GNS3模拟验证

The Comprehensive Application and GNS3 Simulation for the Complex Network

为解决IPV4地址资源紧张问题,NAT技术应运而生。NAT技术将内网的私有地址转换为外网的公有地址,从而实现和Internet用户的通信,在解决IP地址不足问题的同时,隐藏了内部网络的细节,防止了部分来自网络外部的攻击,具有一定的安全作用。由于NAT技术的复杂多样性,造成复杂网络中应用的复杂性,NAT技术的综合使用要兼顾内外网各种要素,周密计划,严密组织,避免网络漏洞,对此进行了论述。

In order to solve the problem of IPV4 address resource, NAT technology emerges as the times require. NAT technology converts the internal private address to external public address and then communicate with internet users. At the same time of the solution of IP address shortage, the NAT can also hide the internal network and prevent the attack from the outside. Due to the complexity of NAT technology, the complex application of NAT in complex network can bring both internal and external problem, so you must plan carefully so that network vulnerability can be avoided.
