METHOD FOR OPERATING LOCAL COMPUTER NETWORK CONNECTED TO REMOTE PRIVATE NETWORK BY IPsec TUNNEL, SOFTWARE MODULE AND IPsec GATEWAY

摘要

PPROBLEM TO BE SOLVED: To disclose a method for enabling a terminal to address-designate a local device in spite of simultaneous connection through a blocking tunnel to an IPsec gateway. PSOLUTION: A gateway (PASS-D) stores the correspondence between a public address (AD-1) of a local router (ROUT-1) providing the connection of the terminal to the Internet and a private address (ad-3) assigned to a terminal (T-L) in the addressing plan of a remote network (RES-D) during the establishment of the tunnel. Furthermore, the gateway (PASS-D) sends a print flow to the local router (ROUT-L). Thus, the print flow is directed to a local printer (E-L) by a port translation technique.
