Actually, not as simple as you might like. I didn't want any of the 
default firewall suites but found they were excellent examples. Got 
tired of mergemaster wanting to change my /etc/rc.firewall. So I copied 
it to /etc/my.firewall, added 'firewall_script="/etc/rc.firewall"'to 
/etc/rc.conf and no longer had any problems.

If you really want an open firewall then simply type:

% su
# ipfw add 1 allow ip from any to any

To put things back the way they were:

# ipfw delete 1

All the above does is add a new rule at the front of your rule set. Then 
later remove it so the other rules are once again used.
