This messes up my firewall somehow -- I need to reboot to get it running again. Esssentially my firewall gets turned off and won't turn on again because "another firewall" is already running. ????? What the heck does this have to do with firewalls?

It also doesn't work -- Step 2 returns an error. Perhaps the two are related. Keep up the good work, though; this is off to a good start. :)
