Communication apparatus, control method, and computer-readable storage medium

A control method for a communication apparatus including at least a first network interface and a second network interface, comprising:

• making a setting of a default gateway with respect to one of the first network interface and the second network interface;
• setting a first obtaining method for obtaining an IP address of the first network interface and an IP address of an external server with which the communication apparatus performs communication via the first network interface;
• setting a second obtaining method for obtaining an IP address of the second network interface and an IP address of an external server with which the communication apparatus performs communication via the second network interface;
• and
• controlling communications using the first network interface and the second network interface,
• wherein in the setting the first obtaining method and the setting the second obtaining method, one of manual obtaining for setting an IP address input by a user and automatic obtaining in which a router connected to the network interface sets an IP address can be set as a method for obtaining an IP address, and
• if the first obtaining method is set to the manual obtaining, the second obtaining method is set to the automatic obtaining, and the setting of the default gateway has been set with respect to the first network interface, the controlling the communications includes controlling communications using the plurality of network interfaces by using at least the IP address of the second network interface obtained by the automatic obtaining without using the IP address of the external server obtained by the automatic obtaining via the second network interface.

A non-transitory computer-readable storage medium that stores a program for causing a computer, provided in a communication apparatus including at least a first network interface and a second network interface, to:

• make a setting of a default gateway with respect to one of the first network interface and the second network interface;
• set a first obtaining method for obtaining an IP address of the first network interface and an IP address of an external server with which the communication apparatus performs communication via the first network interface;
• set a second obtaining method for obtaining an IP address of the second network interface and an IP address of an external server with which the communication apparatus performs communication via the second network interface;
• and
• control communications using the first network interface and the second network interface,
• wherein in the setting of the first obtaining method and the setting of the second obtaining method, one of manual obtaining for setting an IP address input by a user and automatic obtaining in which a router connected to the network interface sets an IP address can be set as a method for obtaining an IP address, and
• if the first obtaining method is set to the manual obtaining, the second obtaining method is set to the automatic obtaining, and the setting of the default gateway has been set with respect to the first network interface, the control of the communications includes controlling communications using the plurality of network interfaces by using at least the IP address of the second network interface obtained by the automatic obtaining without using the IP address of the external server obtained by the automatic obtaining via the second network interface.
