An address translation device (100) translates to GA3 (a global IP), the private IP (PA1) of a second packet (first received packet) transmitted from PA1 on a LAN (101) to GA1 on a WAN (102); and translates to 1024 (a global port), the private port number (3000) of the second packet. Since the destination IP (GA2) of a first packet (third received packet) from PA1 to GA2 is different from the destination IP (GA1) of the second packet, the address translation device (100) translates the private IP (PA1) of the first packet to GA3, which is the same global IP allocated to the second packet; and translates the private port number (3002) of the first packet to 1024, which is the same global port number allocated to the second packet. |
