PROBLEM TO BE SOLVED: To provide a home gateway device and a packet transfer method, capable of smoothly executing transfer processing with ensured security.SOLUTION: A home gateway device (100), when transferring a packet between a node (102) and an external network (101), rewrites a first address having an EUI-64 format, which is used as a transmission source address when the node transmits the packet, to a second address (S206). On receiving from the external network a packet having the second address as a destination address, the home gateway device (100) rewrites the destination address of the received packet to the first address (S207). |
