Basics: Apache, intranet, and internet access

Hello,

I'm quite new to Apache, and I have what I think is a very basic question.

I installed Apache 2.2.4, and use it with JBoss/Tomcat, using ajp13 conduit.

• This all works very well as long as I'm on the server (where JBoss, Apache are installed)

• But when I'm trying to access my server from another computer on my intranet, I only get a "Unable to connect" on my browser.

• I'm using the internal server IP (starting with 192.), which is delivered by the router.

Is there a basic documentation that explains how to set up an Apache intranet on windows ?
And the following question: what if I want to access the server from outside the intranet ?

Thank you
