Securing my Mac Server - Suggestions, Comments, Resources welcome to post.

I posted this a while back, I guess I was too vague on my question since a lot of people have seen this with no reply. I am going to try again.


1. I am going to be using a stripped down G4 to feed my internet connection through. It has dual nic cards. One for internet the other for private network.


What suggestions do you have to secure this as a bottle neck so that nothing leaves or comes in through this set up?

Is this the way you secure your OS X Server?

If not, how do you secure your OS X Server?

Any suggestions or thoughts would be great...
