摘要： PROBLEM TO BE SOLVED: To provide a mobile communication system which enables communication using mutual IP addresses in between nodes, and a shortest route, without requiring specific customization. SOLUTION: When a gateway 5 receives a packet to a communication destination node 42 from a mobile node 12, a position information management module 51 transfers the packet, as is, if no information on a sender's IP address of the packet exists in its own device. If the prefix of the destination's IP address of the packet is the prefix to a network (D) 4, a translation module 52 converts the destination's IP address into an IPv4 address, the sender's IP address to an IPv4 address associated with the IP address, and transfers the address to the destination node 42 of the network (D) 4 as an IPv4 packet.

摘要： PROBLEM TO BE SOLVED: To correctly detect an unjust packet in an MIPv6 network, and to protect a home agent device (HA) from a DoS attack or the like. SOLUTION: A communication device 100 installed on a path, through which the packet given and received between a mobile machine (MN) and the HA for the mobile machine is passed, receives the MIPv6 packet transmitted from the MN to the HA. When the received packet is transmitted in a tunnelling mode, the encryption of an IPsec applied section is released without releasing the capsulation of the received packet. A transmission-origin address and a transmission-destination address in an IPv6 basic header appearing in the section releasing the encryption are collated with filtering conditions stored in a storage section 121, thus deciding the propriety of the passage of the packet.
