Abstract
An apparatus comprising a wireless modem for use at a terminal, the modem being adapted to connect to the terminal via a first connection, and to connect via a second, wireless connection to a gateway between a wireless cellular network and a further, packet-based network. The modem is operable to connect to the gateway via the second connection using a point-to-point link protocol that does not require a physical address for the gateway, and is operable to connect to the host terminal via the first connection using a point-to-multipoint link protocol that supports point-to-multipoint connection and does require a physical address for the gateway. The modem is configured to intercept a message being conveyed between the gateway and the terminal, to generate a substitute address that identifies an interface of the modem, and in response to intercepting the message to communicate the substitute address to the terminal.
