I didn't mean it to take that tone. I didn't understand what you were trying to propose. I assumed that either (a) I was missing something obvious or (b) there was an implicit assumption somewhere in your statement that I didn't pick up. It looks like you were talking about filtering IP directed broadcasts on routers destined to _your own_ customers. I hadn't picked up on that. I thought you were just going to be dropping broadcasts crossing your network. (period) The first, dropping broadcasts destined to your customers, is possibly doable, but not trivial. The second, catching all broadcasts coming in, out, or just passing through, is pretty much impossible. -- Crist J.
