Two weeks ago I wrote about the Leopards Application Firewall.

While I like the new Leopard firewall (and yes, it DOES work properly), I decided I wanted a network firewall on top of the Leopards Application Firewall.

You can download my ipfw rules here (16 Nov, New version). What you do is this:

  • Download WaterRoof and install it.
  • run sudo sh ipfw_rules
  • Make WaterRoof start at bootup:
    waterroof
    waterroof
  • Save the ipfw rules (the ones you loaded when you ran the script):

Tada! You have a sane set of ipfw rules. Now go enable Leopards firewall aswell!
