Configuring DMZ
Use the Networking > DMZ page to configure a Demarcation Zone or
Demilitarized Zone (DMZ). A DMZ is a sub-network that is behind the firewall but
that is open to the public. By placing your public services on a DMZ, you can add
an additional layer of security to the LAN. The public can connect to the services
on the DMZ but cannot penetrate the LAN. You should configure your DMZ to
include any hosts that must be exposed to the WAN (such as web or email
servers).
