These instructions all presume that you are running Mac OS X version 10.2
or higher.
What follows are the basic instructions for configuring that firewall that
comes with Mac OS X. With OS X version 10.2 and greater, Apple included a
firewall feature. This feature is easily configurable, however is not as comprehensive
or as easy to setup as the firewall application 'Brickhouse'.
Brickhouse licenses have been purchased for Monash University staff. Instructions for those who are interested in using Brickhouse.
Step 1: Click on System Preferences
At the bottom of the screen you should see the dock at the bottom of the
screen. At the dock, find the System Preferences icon and click it.
Step 2: Click on Sharing
Next, once inside System Preferences, click on SHARING under
the 'Internet & Network' section.
Step 3: Click the lock to make changes
Once you are in the Sharing preferences, you will need to unlock the settings.
To do this you will need to click on the padlock in the bottom lefthand corner
of the window.
Once you have clicked it, a dialogue box will appear, prompting you for authorisation
to make these changes.
Once you have logged in, click OK and the padlock should
be unlocked. This means you are now able to make changes to the Sharing preferences.
Step 4: Click on the Firewall tab
Inside the Sharing preferences there are three tabs: Services, Firewall and
Internet.
Click on the Firewall tab.
Once inside here, you will need to determine what services you are running
on your computer and what you want to make available on your computer to the
Internet.
By default (or if you are simply not sure) then make sure none of the boxes
in the Firewall section are ticked.
Step 5: Activate the Firewall
When you are ready, click the START button to activate the
firewall.
This is how the screen should look once you have done so.
Step 6: Close the padlock
Once activated, click the padlock in the bottom lefthand corner again to
store the changes permanently and close the window.
Congratulations, you have now successfully configured the firewall on your
Macintosh!
Other Software
For some users the basic firewall configuration above may be insufficient.
Especially for power users who require a greater degree of customisation of
their firewall configuration.
For such users, Monash University has obtained licenses for 'BrickHouse'
- a highly configurable firewall interface for Mac OS X. For instructions
on how to download, install and configure Brickhouse, please visit:
