    Hi,

    DMZ (DeMilitarized Zone)

    In network security jargon, a DMZ is a network that serves as a buffer between a secure protected internal network and the insecure Internet.

    A DMZ usually contains servers which provide services to users from the Internet, such as web, ftp, email (SMTP, POP3 and IMAP4), and DNS servers. Although these servers must be open to limited access from the Internet, they should also be protected by a firewall.

    How to Create a DMZ

    The most simple method of creating a DMZ is to utilize a firewall with three or more network interfaces. Each interface is assigned a specific role:

    • Internal trusted network
    • DMZ network
    • External un-trusted network (the Internet)

    Using a 4-port Ethernet card in your firewall will enable you to create a network in this configuration, or even enable you to create a network with two separate DMZ's.

    Separating your DMZ hosts into multiple DMZ's will help to limit the damage that can be done if one of your DMZ hosts is compromised.
