Remote firewall update for on-board web server telematics system

Abstract

A mobile device includes a processor, a transceiver, and a storage maintaining vehicle associations including phone numbers of telematics control units of vehicles. The device is programmed to identify a change in network address of the transceiver; encrypt the changed network address; and send the encrypted network address to the telematics control units using short message service messages addressed to the phone numbers of the telematics control units. A vehicle includes a storage including paired device data having phone numbers and network addresses of mobile devices and a telematics control unit including a firewall and web server. The firewall is programmed to, in response to receipt of a message from one of the phone numbers including a network address of the mobile device, update the storage to indicate the network address as an originating address authorized to use the web server.
