A packet repeater machine comprising:forward information storage for storing a relationship between a forward origination address and a forward destination address; a forward register for registering said forward origination address and said forward destination address to said forward information storage based on input information from outside, wherein said input information includes forward origination address information, forward destination address information, and input type information indicating the distinction between a forward registration and deletion of registration; and a header converter for converting a destination address to said forward destination address when said destination address which is stored in a packet to be transmitted from a first network to a second network, matches said forward origination address registered in said forward information storage, wherein said forward register further comprises an eraser for deleting registration corresponding to said forward origination address information from said forward information storage when said input type information indicates said deletion of registration; and a rewriter for rewriting said forward information storage so that said forward destination address of the registration corresponding to said forward origination address information becomes an address indicating said forward destination address information when said input type information indicates said forward registration and registration has already been executed.
