Hi Kevin,
Expanding my original question.
I have a need to open and close iptables rules based on particular
time, say 1 week later, 1 month later, etc.
Currently I have a simple script to do that:
- Create the rules.
- Create atd job to delete the rule based on the defined time.
- Log it.
It works, but not elegant :)

Does fwbuilder have that function?
