FirewallBuilder

For ipfw, Firewall Builder generates a policy in the form of a shell script (as for iptables).

To install the policy, copy the generated script to the /usr/local/etc/ directory using ssh and then execute it. To make the firewall run this script at boot time make the following modifications to the /etc/rc.conf file:

firewall_enable="YES"                        
# Set to YES to enable firewall functionality
firewall_script="/usr/local/etc/firewall.fw" 
# Which script to run to set up the firewall
