The present invention concerns a method at a network device, the device comprising a first interface to a first network, a second interface to a second network, and routing means, for enabling access to a file shared by a first device located on the first network, the network device having detected the presence of the first device on the first network, the first device comprising at least one shared file. The method comprises the step, at the network device, of detecting that the first device is not accessible, on reception of a request from a second device located on the second network for getting a shared file on the first device, storing the request, on detection that the first device is accessible, retrieving the shared file in a memory of the network device, and sending a notification to the second device that the shared file is available at the network device or sending the file to the second device.
