2 Firewall Tab |
Having selected Security in System Preferences you need to to select the Firewall Tab (red Arrow)
To get here you will have opened System Preferences > Security and the Firewall tab.
New and Changed. As the firewall in Leopard (10.5.x) is so different to the previous versions and in a New place I have marked this as New and Changed.
There are three states the Firewall can be in selelcted at the Blue Arrow. Allow All Incoming Connections is effectively an Off selection. It will allow any connection to your Mac. Allow Essentials only is a On setting that is quite restrictive and will not let iChat work. Allow... Specific Services... needs applications added to the list. You can add items to the list here or the System will ask you to allow an application or not when you next start it up. As you can see I have added iChat to my list in the Picture.
At the end of the Allow Specific application Listing is a two choice drop down of Allow Incoming Connections or Block them.
That's it.
There are no ports to set.
iChat will work with the top Allow All and the bottom Allow Specifics (if in the list) options. It is not classed as an Essential Applictaion and you can not add applicatons to that list.
What the Firewall now does is flag an Application as being Allowed somewhat in the form of a "Certificate" from the Firewall. All the ports that applications uses are allowed - BUT - only for that Application. This means that if another applications want to use the same ports, you have to Allow that application specifically as well.
One word of Caution is the Stealth Setting in the Advanced button (See Next Picture)
