Len, I'd like to use this, but got hurt by reject_unknown_client, and some others that are DNS based checks. You know better than any of us how many DNS admins are asleep at the switch. What I can get away with is blocking all of China & Korea, etc, but not the very poorly admin'd non-profits. They are the bunches that we communicate with over healthcare matters routinely. Should I be worried? Slip it in on a weekend, and see if anyone is hollering by Tuesday or Wednesday??? Any thoughts/cautions are appreciated.. -A
