The invention concerns a method for transmitting packets in a network comprising at least a first sub-network (11) and a second sub-network (12) connected through a transparent communication link, said link comprising at least a first interface device (5) connected to the first sub-network (11) and a second interface device (6) connected to the second sub-network (12). The method comprises the steps of: attributing a first set of addresses to the interface devices (5, 6) on the communication link; attributing a second set of addresses to nodes (1, 2, 3, 4) connected to the sub-networks (11, 12), the attribution of the second set being done independently from the attribution of the first set; checking whether there appears a conflict between an address of the first set and an address of the second set, and in the affirmative: changing the conflicting address of the first set to a non conflicting address. The invention also concerns a device for implementing the method as well as a method for detecting and transmitting packets to be transmitted over the link.
