A TUNNEL DEVICE TO BE USED IN NETWORKS FOR ETABLISHING A CONNECTION THEREBETWEEN

摘要

The present invention relates to a tunnel device (111) to be used in a network (101) for establishing a connection between a network and devices in an external network(113) so that the devices (117, 119, 121) may be advertised in the network and remotely controlled. This is done by monitoring the availability of the tunnel connection (125) between the network and the external network. Once the monitoring shows that the tunnel connection is available a multicast query is sent to the external network, wherein the external network is adapted to respond to it by sending responses back to the receiver. These responses are then translated into advertisements and multicast in the network.
