    Patent number: 5740375
    Abstract: A method for filtering and forwarding local broadcast traffic across network boundaries. According to one embodiment, the method comprises the step of providing a broadcast list for a source network wherein the broadcast list includes at least one entry that specifies a network address. When a local broadcast packet is received from the source network, a copy of the local broadcast packet is made for each entry in the broadcast to produce a copied packet. The destination address of each copied packet is replaced with a corresponding destination address of a broadcast list to produce a modified packet, and the modified packets are transmitted such that the modified packets are delivered to networks specified by the broadcast list.
