Abstract: To contribute to the assurance of IP reachability from an ACS to an L2CPE, in a communication system which includes an L2CPE arranged on an in-home network, an L3CPE that performs address conversion processing in L3 between the in-home network and a communication carrier network, and an ACS that is arranged on the communication carrier network and that manages L2CPE. A management device installed on a communication carrier network: receives, from an L2CPE via an L3CPE, a connection establishment message which includes a local address of the L2CPE used to access the L2CPE from the ACS; sets, in respect to the L3CPE, a correspondence between the L2CPE local address and a global address of the communication carrier network used to convert an address to the local address; and transfers, to the ACS, the message changed so the local address included in the received message corresponds to a port-mapped global address.
