ipfw Preference Pane (short ipfwPane) lets you control the ipfw(8) firewall again. With Leopard Apple did introduce the new application firewall. The former packet based firewall (which Mac OS X inherited from FreeBSD) does however still exist.
There is just no longer an UI available for it, as it was in 10.4. This is the problem ipfwPane solves — it provides nearly the same simple interface like the Sharing preference pane in the Tiger days did.
This gives you again a more fine-grained control over which ports you want to allow and which you want to block. And other than with Leopards application firewall you can now also block built-in applications and services if you want to.
I am happy to announce the first public release of ipfwPane. The features include everything you could do with Tigers old firewall. You can create, edit and delete rules and modify UDP and TCP port ranges in a single rule.
There is also a list of predefined ports built into to app. This list is based on this article from Apple. But as this is the first public version some predefined rules might work. So if you find a bug, please tell me about it.
ipfwPane v0.2 is available for download here.
After you downloaded the disk image, mount it. In it you will find a file called "ipfwPane.prefPane". Just double click on this file and the Preference Pane will be installed.
To use ipfwPane, go into "System Preferences" (reachable from the menu) and then go into the "ipfw Firewall" category.
