Chapter 5 Configuring the Router’s Security
DMZ (Demilitarized Zone) Host
The DMZ host feature allows one device on the network to operate outside the
firewall. Designate a DMZ host:
• To use an Internet service, such as an online game or video-conferencing
program, not present in the Port Forwarding list and for which no port
range information is available.
• To expose one computer to all services without restriction or security.
M
Warning: A DMZ host is not protected by the firewall and may be
vulnerable to attack. Designating a DMZ host may also put other
computers in the local network at risk. When designating a DMZ
host, consider the security implications and protect it if necessary.
To designate a local computer as a DMZ host:
1. Select DMZ Host from the left side of any Security screen. The “DMZ Host”
screen appears.
2. Click in the “DMZ Host IP Address” check box, then enter the IP address of the
computer to be designated as a DMZ host. Note that only one network com-
puter can be a DMZ host at any time.
3. Click Apply.
Click in the “DMZ Host IP Address” check box again to disable the DMZ host.
