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 is a standard PC on your LAN, but it will receive any
"unknown" connections and data, as described above.
