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 Application, 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
•
The "DMZ" PC will receive all "Unknown" connections and data. This feature is normally used with applications which do not
usually work when behind a Firewall.
•
The DMZ PC is effectively outside the Firewall, making it more vulnerable to attacks. For this reason, you should only enable the
DMZ feature when required.
•
If Enabled, you must select the PC to be used as the "DMZ" PC.
Select the desired option
•
Disabled - DMZ is disabled.
•
Enabled - The selected PC will receive any "unknown" connections and data, as described above.
Multi-DMZ
This feature is only available if your ISP has allocated you multiple Internet IP addresses.
If you have multiple Internet IP addresses, you can assign one DMZ PC for each Internet IP address.
•
The "DMZ PC" will receive all "Unknown" connections and data received for the Internet IP address associated with it.
