Abstract
A unit for use at a terminal as an external wireless modem. In one embodiment, the unit includes: a wireless transceiver for connecting to a gateway between the wireless cellular network and a further, packet-based network; second interface apparatus for connecting to the terminal. The unit further includes processing apparatus arranged to receive a first link layer identifier from the wireless cellular network, gateway or further network, intended for use by the terminal as a source identifier when accessing the further network via the wireless cellular network and gateway. The processing apparatus is configured to intercept at least one message being conveyed from the terminal to the gateway comprising a second link layer identifier generated by the terminal as a source identifier, translate the second identifier into the first link layer identifier and retransmit the message to the gateway with the first link layer identifier as the source identifier.
