Gateway card, gateway apparatus, gateway control method, and computer product

A gateway control method used for a gateway card that is detachably inserted into a server information processor and controls communications between different networks, the method comprising:

• retaining first apparatus authentication data for authenticating the server information processor;
• receiving a setting request for system data in the gateway card;
• obtaining second apparatus authentication data from either of a client information processor and the server information processor which has issued the setting request;
• and
• comparing the first apparatus authentication data with the second apparatus authentication data, and permitting setting of the system data only if there is a match between both of the data as a result of the comparison.

A gateway apparatus that performs communication control between different networks, the gateway apparatus comprising:

• a retention unit that retains first apparatus authentication data for authenticating a server information processor;
• a setting request reception unit that receives a setting request for system data in the gateway apparatus;
• a data obtaining unit that obtains second apparatus authentication data from either of a client information processor and the server information processor which has issued the setting request;
• and
• a permission unit that compares the first apparatus authentication data with the second apparatus authentication data, and permits setting of the system data only if there is a match between both of the data as a result of the comparison.
