Having a look at /etc/defaults/rc.conf:

firewall_enable="NO"            # Set to YES to enable firewall functionality
firewall_script="/etc/rc.firewall" # Which script to run to set up the firewall
firewall_type="UNKNOWN"         # Firewall type (see /etc/rc.firewall)
firewall_quiet="NO"             # Set to YES to suppress rule display
firewall_logging="NO"           # Set to YES to enable events logging
firewall_flags=""               # Flags passed to ipfw when type is a file

So, if you would set firewall_script to some homegrown script that setups up
your firewall for you, instead of the default rc.firewall, all should be fine
and dandy :)
