The second terminal device includes: a local address obtaining unit configured to obtain a first local IP address and first authentication information of the first terminal device from the connection management server, if a first global IP address matches a second global IP address; a determination unit configured to determine, by using of the obtained first authentication information, whether a first particular terminal device with which the second terminal device can communicate by use of the first local IP address is the first terminal device; and a target data communication unit configured to communicate first data with the first terminal device by using the first local IP address, if the first particular terminal device is determined to be the first terminal device.
