Transmission port problem

Looking back at a previous post on how to open ports
I saw this post

Open System Prefs >> Security >> Firewall. Make sure "Set access for specific services and applications" is selected.
Click the "+" button and select Transmission from you Applications folder.
Make sure the pull down menu is set to "Allow incoming connections".

Click to expand...

It seem to worked for people.
Here's my question, when i click system prefs, security, i do not see any firewal things. instead i see the filevault thing.

Here's a screenshot of what i see.


Thanks for helping

Which version of OS X are you using? In Leopard, opening System Preferences, Security, shows a dialog box with three tabbed choices:

General, FileVault, Firewall

Are you not seeing the same thing?

I'm using MacOSX 10.4.11

Please don't tell me osx 10.4 doesn't have that function T.T

You're using Tiger. You have a firewall but it's not accessed from the same system preference dialog as Leopard. See the following MacWorld article:

Macworld | Mac OS X Firewall
