Yeah why iv had to try it I'll tinker with it more se if I can knock out 1 DMZ but doubt it for a compy who made 2-3 million a year ago to one making 35-50 million think they'd upgrade there network a lil bit.
ISP see's unknown MAC then stops bridge after nodes scans of networkA bridge reads a frame's destination address and decides to either forward or filter. If the bridge determines that the destination node is on another segment on the network, it forwards (retransmits) the frame to that segment. If the destination address belongs to the same segment as the source address, the bridge filters (discards) the frame. As nodes transmit data through the bridge, the bridge establishes a filtering database of known MAC addresses and their locations on the network. The bridge uses its filtering database to determine whether a packet should be forwarded or filtered.
