By that I mean having a packet broadcast on a network other than the one to which you are directly attached. I am quite aware of the dangers of such packets. One caused a broadcast storm on our ethernet effectively bring down the net. As far as I know there is no defence against one of these packets coming in from the Internet. On the other hand, if the packet were a UDP packet that did not engender a response (i.e. network monitoring info, routing tables, etc.), it could be a valuble tool, which may even prove useful in some of my present work. Is there any attempt in the Internet to regulate or block such packets. If so, where and how? If not, has any one considered it? I would think that if there is any control over remote broadcasts, it must take place in the gateway attached to the destination network, but perhaps the overhead would be too great. Jon Peha
