Configuring DMZ Settings

If you have a local client computer that cannot run an Internet application properly behind
the NAT firewall, you can configure it for unrestricted two-way Internet access by defining it
as a Virtual DMZ host.
A DMZ allows a single computer on your LAN to expose all of its ports to the Internet. When
doing this, the exposed computer is no longer "behind" the firewall. Therefore, placing a
computer in the DMZ should be considered temporary because your firewall is no longer
able to provide any security to it..
You configure the Gateway's DMZ settings using the DMZ menu. To display this menu, click
Advanced > DMZ in the menu bar. Figure 97 shows an example of this menu and Table 48
describes the settings.

Remote Management
You can remotely manage the Gateway using HTTP, HTTPS, Telnet, SSH, SNMP, and
HNAP. Each method has Enabled and Disabled buttons for enabling or disabling that remote
management method. If you enable a remote management method, specify the port number
to be used with that method in the field to the left of Enabled.
Note: The Gateway's remote management address appears below HNAP.
Remote Access Allowed From
