In order to provide a home gateway device capable of achieving smooth forwarding processing while ensuring security, when forwarding a packet between a node (102) and an external network (101), this home gateway device (100) rewrites a EUI-64 format first address used by the node as the transmission source address at transmission time into a second address (S206), and when a packet is received from the external network that is addressed to the second address, this home gateway device (100) rewrites the destination address of said received packet to the first address (S207). |
