A method of mapping a first interface to a second interface both of an electronic data communication device (16), which first interface enables exchange of data with a first electronic data communication network (13) and which second interface enables exchange of data with a second electronic data communication network (12), the method comprising the steps of: <SL> <LI>(1) obtaining an address representative of said first interface; <LI>(2) generating an identifier; <LI>(3) storing said identifier and said address representative of said first interface in a memory with a mapping therebetween; <LI>(4) transmitting said identifier to said address representative of said first interface; <LI>(5) awaiting receipt of data comprising said identifier and an address representative of said second interface from said electronic data communication device (16) via said second electronic data communication network (12); and <LI>(6) if said data is received, said identifier can be used to map said address representative of said first interface to said address representative of said second interface. </SL>
