1. A method, comprisingcooperating with two or more device service controllers (DSCs), each residing on a separate local area network (LAN) and a first DSC proxies communications for network devices on a first LAN and a second LAN;

  • instructing a first DSC to obtain an available local virtual IP addresses from a device that is located exterior from the LAN where each DSC resides;

    allocating and assigning Virtual IP addresses to network devices to proxy communications for the networked devices on the first local area network (LAN) where the first DSC resides;

    instructing a second DSC to obtain an available local virtual IP addresses from the device that is located exterior from the LAN where each DSC resides;

    allocating and assigning Virtual IP addresses to network devices to proxy communications for the networked devices on the second local area network (LAN) where the second DSC resides;

    storing a first pair of an assigned virtual IP address assigned to the first DSC and some unique identifying information regarding the first DSC in the device;

    storing a second pair of an assigned virtual IP address assigned to the second DSC and some unique identifying information regarding the second DSC in the device;

    establishing a route from the assigned Virtual IP address to a destination network device on a LAN associated with a given DSC, based on stored pairs of information stored in the device; and

    broadcasting a broadcast packet across the route from the first LAN to the second LAN by tunneling between the two networks using the established route to forwarding a broadcast packet from the first LAN to the second LAN.
