Abstract

Upon receipt of a packet addressed to a virtual IP address assigned to each first device from a second device outside a base network, a processor identifies a base relay apparatus that accommodates the first device, to which the virtual IP address is assigned, on the basis of the virtual address and a protocol type of the received packet, and also identifies a reception port number of the identified base relay apparatus, which corresponds to a combination of the virtual IP address and the protocol type of the received packet, from among reception port numbers each assigned to a combination of the first device accommodated to identify a transfer destination, and a protocol type. Then, the processor relays the received packet to the identified reception port number of the identified base relay apparatus.
