P2P NAT网络通信
NAT(Network AddressTranslators)，网络地址转换：网络地址转换是在IP地址日益缺乏的情况下产生的，它的主要目的就是为了能够地址重用。NAT分为两大类，基本的NAT和NAPT(NetworkAddress/Port Translator)。 最开始NAT是运行在路由器上的一个功能模块。 最先提出的是基本的NAT，它的产生基于如下事实：一个私有网络（域）中的节点中只有很少的节点需要与外网连接（呵呵，这是在上世纪90年代中期提出的）。那么这个子网中其实只有少数的节点需要全球唯一的IP地址，其他的节点的IP地址应该是可以重用的。 因此，基本的NAT实现的功能很简单，在子网内使用一个保留的IP子网段，这些IP对外是不可见的。子网内只有少数一些IP地址可以对应到真正全球唯一的IP地址。如果这些节点需要访问外部网络，那么基本NAT就负责将这个节点的子网内IP转化为一个全球唯一的IP然后发送出去。(基本的NAT会改变IP包中的原IP地址，但是不会改变IP包中的端口)
