DMZ Addresses
Note: For the SonicWALL PRO 100, PRO 200, PRO 300, PRO 230, PRO 330, and GX series only
The SonicWALL provides security by preventing Internet users from accessing machines on the LAN.
This security, however, also prevents users from reaching public servers, such as Web or e-mail
servers.
The SonicWALL offers a special DMZ ("Demilitarized Zone") port that provides Internet access to
network servers. The DMZ sits between the local network and the Internet. Servers on the DMZ are
publicly accessible, but they are protected from attacks such as SYN Flood and Ping of Death. Use
of the DMZ port is optional.
Tip If you are configuring the SonicWALL SOHO3 or the SonicWALL TELE3, please go to Chapter 8,
Network Access Rules, for information about setting up publicly accessible servers.
Using the DMZ is a strongly recommended alternative to placing servers on the WAN port where they
are not protected or established Public LAN servers.
