Information processing apparatus and communication control method

A non-transitory computer-readable medium having encoded thereon a computer program for controlling communication in an information processing apparatus provided with a plurality of logical partitions assigned logically divided computing resources, and configured such that operating systems are independently run in the respective logical partitions, executable to perform:

• wherein, if at least one of the plurality of logical partitions is a designated logical partition that is assigned a network address uniquely-identified by an external network on behalf of the plurality of logical partitions, the network address being shared by the plurality of logical partitions through the designated logical partition, the plurality of logical partitions being connected to each other via a virtual network interface for performing internal communication between the plurality of logical partitions, and the designated logical partition being connected to a physical network interface for performing communication with the external entity, then
• causing the designated logical partition to assign an available port number to a logical partition other than the designated logical partition for communication with an external entity, and
• forwarding a packet that has been received by the designated logical partition via the physical network interface from an external entity, using an assigned port to the logical partition to which the respective port number has been assigned via the virtual network interface.
