Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a communication system capable of automatically executing the updating of network constitution information to be stored in respective communication terminals in accordance with system change without requiring manual operation. SOLUTION: The communication system preregisters network constitution information expressing the correspondence relation of the names of respective client terminals T11 to T1i and NAT routers NT1, NT2 to their IP addresses in a database DB, and when a network constitution information updating request is generated in a maintenance server MSV due to the addition of a client terminal T31 or the like, updates the network constitution information registered in the database DB. After the updating, the network constitution information in the database DB is transmitted to respective client terminals T11 to T1i, T21 to T2j, T31 to be request sources in accordance with network constitution information acquisition requests from respective client terminals T11 to T1i, T21 to T2j, T31.
