To use ipfw3, add 'ipfw3_enable=YES' to /etc/rc.conf . By default, only the 'ipfw3' and 'ipfw3_basic' modules will be loaded. If you need more ipfw3 modules, set them with 'ipfw3_modules="
This ipfw3 rc script is largely based on the ipfw script.
The /etc/ipfw3.rules (a shell script) should be present to setup the firewall rules, otherwise the default setup will block all incoming connections, including your current connection!
NOTE: I wrote this script for use in my VPS last year, but switched to PF later, so more tests and improvements (e.g., flush tables on stop) to this script are needed.
