DMZ Interface
DMZ stands for Demilitarized Zone. The DMZ interface is typically used for connecting
servers that need to be accessible from the outside world, such as e-mail, web and DNS
servers.
Typically, connections from the DMZ are only permitted to the external network, and
hosts in the DMZ may not connect to the internal network. This allows the DMZ's hosts
to provide services to the external network while protecting the internal network in case
intruders compromise a host in the DMZ. For someone on the external network who
wants to illegally connect to the internal network, the DMZ is a dead end.

To add a DMZ Server in the network, the administrator can
a)
Assign Private IP Addresses to the DMZ network. And configure a One-To-One
NAT entry to map a Global IP Address to the Private DMZ Server IP Address.
Refer
NAT Configuration
for more details.
b)
Or assign Private IP Addresses to the DMZ network. And configure a Virtual
Server entry to map a Global IP Address/Port to the Private DMZ Server IP
Address/Port. Refer
Virtual Server Configuration
for more details.
c)
Or assign Global IP Address to the DMZ network. And add a NAT Exception (i.e
disable NAT) between WAN and DMZ.
L
Note:
To make the private DMZ Server accessible from the internet, use One-To-One
NAT only when multiple services are hosted by a single DMZ Server. When only one
service is provided by the DMZ Server, it is preferable to use Virtual Server feature.
This would enable you to save the number of Global IP Addresses required to expose
your DMZ services.
