WaterRoof is a graphical frontend for Mac OS X's firewall service. The application allows you to change the settings of the firewall on your Mac by using a graphical user interface.
You can run the frontend by simply clicking on the application. You don't have to move it to your Application's folder. When you run the app, it will ask you for administrator privileges, so you will have to type in your account password.
You can do so much than add custom firewall rules with this app, but that is probably what you will use for the most. I like some extras that WaterRoof ships with. For example, you can backup and deploy configurations and import and export them. You can manage your networks's bandwidth and even carry out reverse and who is queries from a different window within this app.
All in all, WaterRoof gives you access to most of your firewall's settings and lets you change them at will. The app works well and, as advertised, it is also free.
Pros
- Custom rule inclusion
- Configuration copying
- Flexible firewall configuration
Cons
- May break system access if handled inaccurately
