1. A networking device comprising a plurality of identical interfaces being adapted to connect to either of a Wide Area Network, WAN, or a Local Area Network, LAN, the WAN providing access to a broadband network, all of the identical interfaces being preliminarily preconfigured to be WAN interfaces for accessing said WAN, comprising:
- changing means for, upon receipt of a discover message from a LAN device connected on a preconfigured WAN interface, dynamically modifying said preconfigured WAN interface to become a LAN interface,identifying means for requesting an access to the broadband network through all of said plurality of identical interfaces simultaneously by broadcasting a discover message, and for identifying an interface that receives a response to the discover message as a WAN interface for accessing said WAN, andselecting means for, if more than one WAN interface for connecting to the WAN has been identified, selecting based on a selection rule one WAN interface for accessing said broadband network, wherein said selection rule is configured to be amended by a remote configuration for selecting a first interface for accessing said broadband network as a third network.

7. A method for accessing a broadband network through a Wide Area Network, WAN, in a device comprising a plurality of identical interfaces adapted to connect to either of the WAN or a Local Area Network, LAN, said interface connected to said WAN being a WAN interface, comprising at the device:
-
preconfiguring all of the identical interfaces preliminarily as WAN interfaces for accessing said WAN, upon receipt of a discover message from a LAN device connected on a preconfigured WAN interface, dynamically changing said preconfigured WAN interface to become a LAN interface, simultaneously broadcasting a discover message for requesting access to the broadband network to all said interfaces of the plurality of identical interfaces, receiving an answer to the discover message from one or more interfaces, identified as WAN interfaces for accessing said WAN, and selecting, based on a selection rule, an interface, among said WAN interfaces, to access said broadband network, wherein said selection rule is configured to be amended by a remote configuration for selecting a first interface for accessing said broadband network as a third network.

8. A gateway device comprising a plurality of identical interfaces being adapted to connect to either of a Local Area Network, LAN, or a Wide Area Network, WAN, the WAN providing access to a broadband network, all of the identical interfaces being preliminarily preconfigured to be WAN interfaces for accessing said WAN, comprising:
-
changing means for, upon receipt of a discover message from a LAN device connected on a preconfigured WAN interface, dynamically modifying said preconfigured WAN interface to become a LAN interface, identifying means for requesting an access to the broadband network through all of said interfaces of the plurality of interfaces simultaneously by broadcasting a discover message, and for identifying an interface that receives a response to the discover message as a WAN interface for accessing said WAN, and selecting means for, if more than one WAN interface for connecting to the WAN has been identified, selecting, based on a selection rule, one WAN interface for accessing the broadband network, wherein said selection rule is configured to be amended by a remote configuration for selecting a first interface for accessing said broadband network as a third network. - View Dependent Claims (9)
