Thanks for your reply. I've been slowly getting information about all of this and was going to post what I found but you beat me to it
Maybe just unplug your network cable?
My webapp uses APIs heavily so I often need to check how it works so that's why I can't really unplug (although it'd be nice).
- Apache: you can change the "Listen" directives
For anyone else that might be interested: https://help.ubuntu.com/community/Apach ... g%20Apache
For MySQL, scroll down to "--bind-address=127.0.0.1": http://dev.mysql.com/doc/refman/5.1/en/ ... erver.html
(although read a few posts that it might not help)
is OS X's built-in Personal Firewall not easy to configure?
Yeah it looks so, I've gotten my first one just a few days ago, but I wasn't sure if the 3rd option "Set access for specific services and applications" gives you a choice of allowing only certain IP's (like 127.0.0.1), or simply allowing/disallowing traffic for a specific app.
Looks like now I'll be on my way setting up all of this. Thanks once again for all your help guys/gals!
