Embodiment Construction

[0034] Next, embodiments of the present invention will be described with reference to the drawings. First, refer to figure 1 , the outline of the relay communication system 100 according to this embodiment will be described. figure 1 It is an explanatory diagram schematically showing the configuration of the relay communication system 100 .

[0035] As a main configuration, the relay communication system 100 includes relay servers 1 , 2 , and 3 , an IPv6 address providing server [IPv6 address providing server] 5 , and a management server 6 .

[0036] The relay server 1 is connected to the LAN 30 through the LAN cable 31 . A router 32 and a PC 33 are connected to the LAN 30 in addition to the relay server 1 . The router 32 performs processing for connecting devices connected to the LAN 30 to the public wired communication network 41 . The public wired communication network 41 is a WAN constructed by wires such as metal cables or optical fibers.

[0037] In addition, the rela...

Abstract

The invention provides a relay server and a connection method thereof. To conduct communication based on a VPN, in relay server which can be connected to both a wired WAN and a wireless WAN, which WAN to use is decided. The relay server, has a connection information storage unit, a first connection control unit, a second connection control unit, a VPN control unit and an exclusive control unit. The connection information storage unit stores connection information. The first connection control unit performs control used for being connected to a public wired communication network. The second connection control unit performs control used for being connected to a public wireless communication network. The VPN control unit uses the VPN as a relay server of a communication partner to communicate. Under a circumstance of being connected to a WAN through the second connection control unit, the exclusive control unit prohibits connection to the WAN performed by the first connection control unit, and under a circumstance of being connected to a WAN through the first connection control unit, the exclusive control unit prohibits connection to the WAN performed by the second connection control unit.

Description

technical field [0001] The present invention mainly relates to a relay server [relay server] capable of communicating between terminals connected to different LANs (Local Area Networks) and its connection method to a WAN. Background technique [0002] Conventionally, a communication technology called a virtual private network (Virtual Private Network, VPN) is known. By using a VPN, another LAN connected via a public line can be used as if it were a directly connected network. [0003] The relay communication system described in Japanese Patent Laid-Open No. 2009-157825 is composed of a plurality of LANs, and a relay server and a client terminal are arranged for each LAN. In this relay communication system, a VPN is constructed by connecting LANs to each other using these relay servers. This configuration enables direct communication between client terminals connected to different LANs. Also, Japanese Patent Application Laid-Open No. 2009-157825 discloses a configuration i...
