Abstract
In a NAT type determination method pursuant to RFC 3489, address information added in a binding response from a STUN server in response to a binding request issued in a latest transmission test is compared with address information added in a binding response in response to any transmission test executed therebefore. When the address information are not identical, a NAT type is determined symmetric. Even when a router whose NAT type changes frequently according to a use status is connected, communication is capable without manual setting change by a user.
