There is also a great collection of articles on setting up firewalls with FreeBSD, at web sites such as: http://www.freebsddiary.org/ http://www.daemonnews.org/ For more documentation available locally, you might want to take a look at the following places too: /etc/rc.firewall This contains a lot of rules for ipfw, and will certainly be of great assistance to someone who wants to see practical examples of ipfw at work. /usr/src/contrib/ipfilter/rules This directory, part of the ipfilter source, contains a lot of ipfilter rulesets and examples for ipf & ipnat.
