Mac OS X: How do you set ipfw rules on startup?

Question

How do you apply a list of ipfw rules at startup on Mac OS X?

i.e. I have a list of rules like these that I'm applying manually.

sudo ipfw add 00100 ...
sudo ipfw add 00101 ...
sudo ipfw add 00102 ...

Answer 1

Right your rules into a shell script and then create a launchd plist to fire off the script at boot.

Answer 2

You can also use a tool like NoobProof or WaterRoof to set the rules up and save them in a startup configuration.
