I run Win XP SP3. (I also drive a 15-year-old car & watch old John Wayne movies with a Beta Max). Ergo, my favorite firewalls are as described by the title to this topic -- old, out-dated, etc. They are Kerio 2.1.5 & Sygate 5.6.2808. Granted - neither of these oldies is the equal of modern-day FWs BUT if you were somehow *compelled* to use one or the other, WHICH of the two (Kerio or Sygate) would be YOUR choice -- and why?
