I realize that I may be reading a lot into this, but the fact > that he was snooping the ARP broadcasts to figure out what addresses > to NAT sounds like a bad sign. The fact that he will have to guess > the netmasks is the least of those worries... That was one of the questions I had that I wasn't very sure on; maybe you could shed a little light. My thoughts were this: how much traffic will I need to send to a customer on broadcast and not directly to his IP? In what situations would I need to know the actual netmask? I'm not sure how I feel about ignoring the netmask, so any ideas would be appreciated.
