Abstract
In a network relay device, unauthorized access from an internal computer to an external network is detected, an unauthorized destination service port used for the unauthorized access is specified, and a substitute port is allocated. A service relay unit and the internal computer are instructed to use the substitute port instead of the unauthorized destination service port, and an unauthorized access notification is sent. Mutual conversion of the unauthorized destination service port and a substitute service port is carried out, to relay a packet between an internal network and the external network.
