COMMUNICATION TERMINAL, COMMUNICATION METHOD AND COMMUNICATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a communication terminal capable of correctly operating communication even for communication inappropriate to address conversion, when performing communication to separately use each of a plurality of communication interfaces by address conversion.SOLUTION: A communication control unit 82 selects a communication interface unit 81 for use in packet transmission and reception from among a plurality of communication interfaces 81, to perform control to convert a source address, included in a packet, into an address usable in the selected communication interface unit. A source address control unit 83 detects or predicts the occurrence of target communication inappropriate to address conversion by the communication control unit 82, to perform control to set a source address, which does not change before and after the address conversion on the target communication packet by the communication control unit 82, to the target communication packet, prior to the address conversion.
