I'm still digging through it to see what they say about network security. Joe Hamelin, W7COM, Tulalip, WA, 360-474-7474

This quote: "Firewall" - is a term used to describe a software application designed to prevent unauthorized access to the initial entry point of a system. is indicative of the level at which the doc is written, and of the intended audience.
