    • A system for accessing a node of a private network includes an assigning portion for assigning external port values to respective network nodes based on information collected from the network nodes of the private network, and storing the assigned external port values; an exchanging portion for exchanging the external port values of the respective network nodes of private networks; and an address converting portion for converting the external port values into corresponding private IP addresses and internal port values when a network node of one private network accesses another network node of another private network by using the external port values of another network node of another private network. Accordingly, a network node of a private network without a global IP address becomes accessible.
    • 用于访问私有网络的节点的系统包括:分配部分,用于基于从专用网络的网络节点收集的信息将外部端口值分配给各个网络节点,并存储所分配的外部端口值; 用于交换专用网络的各个网络节点的外部端口值的交换部分; 以及地址转换部分,当一个专用网络的网络节点通过使用另一个专用网络的另一个网络节点的外部端口值来访问另一个专用网络的另一个网络节点时,将外部端口值转换为相应的专用IP地址和内部端口值 。 因此,没有全局IP地址的专用网络的网络节点变得可访问。
