I don't know of any card that can do this... That's an idea for a kernel hack where you put the card into promiscuous mode and then filter from there for only certain addresses. But that would be a heavyhanded hack and I can see it chewing up quite a bit of resources on a busy network. 'james -- James A. Crippen ,-./-.
