Abstract
A connection assistance apparatus avoids unauthorized access and DoS attacks, prevents a performance degradation from occurring, and does not need to recognize different connections to gateway apparatus. An authenticating unit authenticates the validity of a terminal by checking if the terminal is a valid terminal capable of communicating with a gateway apparatus according to IPSec in response to a request from a user who owns the terminal. If it is judged that the terminal is a valid terminal, then a preshared key generating unit generates a preshared key for the terminal and the gateway apparatus, and a firewall opening instruction information generating unit generates firewall opening instruction information to open a firewall of the gateway apparatus. A transmitting unit sends the preshared key to the terminal and the gateway apparatus and sends the firewall opening instruction information to the gateway apparatus.
