要在相同的网络终端上绑定到不同的套接字上，所以必须为这些套接字设置SO_REUSEADDR属性（即允许重用），否则侦听会失败。 4、S的【协助打洞】连接收到A的申请后通过【主连接】通知B，并将A经过NAT-A转换后的公网IP地址和端口等信息告诉B。 5、B收到S的连接通知后首先与S的【协助打洞】端口连接，随便发送一些数据后立即断开，这样做的目的是让S能知道B经过NAT-B转换后的公网IP和端口号。 6、B尝试与A的经过NAT-A转换后的公网IP地址和端口进行connect，根据不同的路由器会有不同的结果，有些路由器在这个操作就能建立连接，大多数路由器对于不请自到的SYN请求包直接丢弃而导致connect失败，但NAT-A会纪录此次连接的源地址和端口号，为接下来真正的连接做好了准备，这就是所谓的打洞，即B向A打了一个洞，下次A就能直接连接到B刚才使用的端口号了
