摘要： A relay server (3) mainly includes a VPN group information storage part, an address filter information storage part, and a communication control part. The VPN group information storage part stores information concerning routing apparatuses that form a VPN group and a routing session. The address filter information storage part stores address filter information in association with identification information of the routing apparatus. The communication control part performs controls for: upon detection of that an address included in the address filter information overlaps, causing a translated address to be associated with the overlapping address, and transmitting the translated address to another routing apparatus; and performing routing based on the address filter information and the translated address.

摘要： A communication system, wherein:
an IP communication network includes plural network node apparatuses,
a terminal T1 is connected to a network node apparatus N1, and a terminal T2 is connected to a network node apparatus N2,
an external IP packet is sent/received between said terminal T1 or T2 and said IP communication network, and an internal packet which includes said external IP packet is sent/received between said network node apparatuses,
said IP communication network receives a telephone number or a host name of said terminal T2 from said terminal T1,
based on said telephone number or said host name of said terminal T2, a communication path in which said internal packet is transferred is set between said network node apparatuses N1 and N2,
a communication between said terminals T1 and T2 is performed via said network node apparatus N1, said communication path and said network node apparatus N2, and
said communication path is reset based on the release of the telephone communication notified by said terminal T1 or T2.

摘要： Fully meshed virtual paths obtained with smaller number of settings, thus facilitating expansion of VPN service. A communication device in a virtual private network (VPN) having a VPN accommodation function for connecting an intra-organization network or inter-organization network through the Internet includes;
a first means for generating a VPN address, a format of which includes both a VPN number for uniquely identifying a VPN in a certain scope and a closed address used in an organization or among organizations, either converting a packet header into a header having the above-mentioned VPN address or adding the above-mentioned VPN address to a packet header for transmission; and
a second means for on receiving the packet having a header of the VPN address format, either converting the received packet into a packet format equivalent to an original packet format or removing a header having VPN address format.
