Abstract
A communication transfer apparatus and a communication transfer method can transfer communications at low cost without the need of requesting a global IP network to switch any port number. The local internet protocol address of the origin terminal of transfer described in a record relating to a transfer out of the records of the masquerade table that is utilized for an internet protocol masquerade is rewritten as the local internal protocol address of the destination terminal of transfer, while maintaining the global port number of the record.
