ipfw isn't some sort of daemon to be stopped and started. If you want to 
add rules, delete rules or what ever then  you just do it.

Take a look at the script in /etc/rc.firewalls and you'll see that's all 
they are doing.

so  your firewall file should be  a shell script. Even if you do man 
ipfw you'll see that in no way does ipfw accept a file name as an 
arguemnt.  Pretty simple eh?
