Abstract
A communication system comprises a NAT device, a terminal device, and a communication control device. The communication control device comprises a first storage unit that stores a NAT address, a first receiving unit that receives a type request signal, a first determination unit that determines whether the NAT address matching a source IP address of the type request signal is stored in the first storage unit, and a first transmitting unit that transmits the type information associated with the NAT address matching the source IP address to the terminal device. The terminal device comprises a second transmitting unit that transmits the type request signal, a second receiving unit that receives the type information, and a communication control unit that performs Peer to Peer communication with another terminal device that is subordinate to another NAT device by performing communication using a method to establish communication based on the received type information.
