Abstract: These instructions are intended for use by
experienced system administrators who are familiar with firewall
concepts but don't have time to research all the details
themselves. It is not intended as a tutorial, an entire book
would be needed for that and as soon as one is written we'll
mention it prominently. Nor is this intended to be an exhaustive
discussion of the pros and cons of various kinds of firewalls,
for that you should read Bellovin & Cheswick's Firewalls and
Internet Security.
