A QUICK pass through this man page to make it conform to mdoc standards and to clean up some of the English. The job is nowhere complete. This man page would be a good project for someone who knows something about the firewall software, and would like to contribute to the documentation effort. Many of the things in this man page are out of date and do not reflect reality. 1996-07-11 02:37:59 +00:00			`.Pp`
