A method can be used for establishing a channel for managing an IPv4 terminal. An identifier of a network port of an IPv4 terminal is sent by a home gateway. A listening port is allocated to the IPv4 terminal according to the identifier of the network port of the IPv4 terminal, so as to establish a channel for managing the IPv4 terminal between the network port and the listening port, so that the IPv4 terminal is remotely managed by a management device. An identifier of a network port of an IPv4 terminal sent by the IPv4 terminal through a home gateway is received and a listening port is opened for the IPv4 terminal according to the identifier of the network port and used for receiving a management message sent by a management device.
