摘要： PROBLEM TO BE SOLVED: To control a physical link of a LAN (local area network) on the basis of disconnection of a logical link of an ADSL (asymmetric digital subscriber line) line in a communication apparatus for connecting the ADSL line with the LAN. SOLUTION: The communication apparatus 103 is connected with the ADSL line and the LAN. When the communication apparatus 103 detects disconnection of the logical link of ADSL, the communication apparatus 103 forcibly inactivates the physical link of the LAN interface. Thus, a LAN device 101 such as a router connected with the LAN switches a communication line to a redundant path 300. Thus, communication is continued even when the logical link of the ADSL is disconnected. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an NAT router which can conduct suitable communication, even when an application for writing IP address information in a data part of an IP packet is conducted. SOLUTION: The NAT router 100 assigns the same address as a public IP address (B) allocated to a global interface of the router to one computer 400a, connected to an internal network. The router 100 assigns the same address as a public IP address (A) of a host UP unit 200 and a designated private IP address (X) in a local interface. Thus, even if the IP packet, in which the public IP address in written in the data part, is sent from an external network to the internal network, proper communication can be conducted.

摘要翻译：要解决的问题：即使在IP分组的数据部分中写入IP地址信息的应用时，也可以提供能够进行适当通信的NAT路由器。解决方案：NAT路由器100将分配给路由器的全局接口的公共IP地址（B）分配给与连接到内部网络的一台计算机400a相同的地址。路由器100在本地接口中分配与主机UP单元200的公共IP地址（A）和指定的专用IP地址（X）相同的地址。因此，即使将写入数据部分的公共IP地址从外部网络发送到内部网络的IP分组，也可以进行适当的通信。版权所有（C）2003，JPO
