Abstract
The number of IP pools is increased independently of the number of network interfaces coupled to an external network. In response to a registration request requesting registration of an IP address pool, which is a part of an IP address space, in a first network, a control apparatus is configured to cause a processor to execute: generating a logical interface configured to operate as a logical network interface; logically coupling the logical interface to a logical switch; generating a NAT module logically coupled to a second network interface and configured to mutually convert an IP address in the IP address pool and an IP address in a second network; and logically coupling the NAT module to the logical interface.
