Tiag, The next question I would ask of you is "Why do you feel you need a DMZ?". Others have replied with the definition (and basic layouts) of a DMZ. While you're certainly looking at securing things, your posting appears to be (as others have noted) confusing the terms DMZ and firewall. The next step for you is to answer the question I've posed (for yourself and your boss). If you don't have publicly accessible (by design) servers, then a DMZ can become a liability rather than an asset. However, if you do have web servers, mail servers, news servers, etc., then figure out who should access them, how they should be accessed and how (or even if) those servers need to communicate with the rest of your network. Then you can begin researching and designing a reasonably secure network *and* have ample justification to give your boss.
