摘要： A network management system which can easily rebuild the system even when a switch in the configuration of cars occurs. A monitor apparatus including monitor cameras (1-1˜1-4, . . . ) and recording devices (1-5, . . . ) in each car (21a, 21b, . . . ) is networked. Each intra-car network is constructed as a LAN, a router (1-10 (RT1), . . . ) is connected to the LAN in each car, and an inter-car network is constructed as a WAN. The same apparatus in each car and apparatuses provided at the same positions are connected to a port of the same port number and the same LAN address is allocated to such an apparatus. As for an access from a WAN side, which apparatus is accessed is defined only by a difference in port number. Network information of the car switched car can be set merely by switching the setting of the WAN address of the router, . . . .

摘要： When an internal terminal (TM1 to TMn) replaced with another terminal due to the breakdown or the model upgrading and the DHCP function allocates a new private address for the MAC address of the terminal after replacement, the newly allocated private address is managed in association with physical ports (PP1 to PPn) in an expansion NAPT table. Then, in this state, when an IP packet is delivered from an external terminal (TM0) on the side of a WAN(2), the transmission destination address of this IP packet is converted to the private address of the internal terminal after conversion in accordance with the expansion NAPT table using the physical ports as a key.
