Hi, All I am learning about DMZ, I found that some articles define it as a public zone protected by a firewall, and in order to be accessable from Internet, DMZ needs routable IP (reserved IP such as 192.x.x.x can not be used ), while other articles say that a DMZ just like another internal private network, it just includes all servers such as WWW, FTP, and so on, so it just open for the private network. So I am a little bit confusing about it. Could any body give me some a piece of advice? Thank you in advance.
