Using a Special Application
•
Configure the
Special Applications
screen as required.
•
On your PC, use the application normally. Remember that only one (1) PC can use each
Special application at any time. Also, when 1 PC is finished using a particular Special Ap-
plication, there may need to be a "Time-out" before another PC can use the same Special
Application. The "Time-out" period may be up to 3 minutes.
If an application still cannot function correctly,
try using the "DMZ" feature.
DMZ
This feature, if enabled, allows one (1) computer on your LAN to be exposed to all users on the
Internet, allowing unrestricted 2-way communication between the "DMZ PC" and other Internet
users or Servers.
•
This allows almost any application to be used on the "DMZ PC".
•
The "DMZ PC" will receive all "Unknown" connections and data.
•
If the DMZ feature is enabled, you must select the PC to be used as the "DMZ PC".
•
The DMZ feature can be Enabled and Disabled on the
Advanced Internet
screen.
The "DMZ PC" is effectively outside the Firewall, mak-
ing it more vulnerable to attacks. For this reason, you
should only enable the DMZ feature when required.
