If I have a firewall, do I have a DMZ?
No, you do not necessarily have a DMZ if you have a firewall. A DMZ is a network that is semi-protected (not on the public network but also not on the fully protected private network). Many hardware firewalls create a DMZ for public mail servers and Web servers. Most small networks or homes do not have DMZ networks. Most medium-to-large corporate networks would have a DMZ.
