there is actually no proof of the current order depency is really
a good idea. Other access lists work without that constraint.

Maybe now we can do a real design? No need to continue on the wrong
path (if it is wrong).

not that "chains" are the only and the best solution to firewall rules
out there :-)

Even with in database rules only you can do the switches - you remove
all entries, keeping your current connection and then bring them
back when you are ready. Just a matter of some SQL commands in a script.
