4.4.4 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.
Note:
If an application still cannot function correctly, try using the DMZ feature.
4.4.5 Multi-DMZ
This feature, if enabled, allows the DMZ computer or computers on your LAN to be exposed
to all users on the Internet.
•
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.
If you have multiple Internet IP addresses, you can assign one DMZ PC for each Internet IP
address.
If you only have 1 WAN IP address, only DMZ 1 can be used, and only one (1) PC can be the
DMZ PC. The current WAN IP address is displayed. If this address is assigned upon connec-
tion, and no connection currently exists, then this address will be blank or 0.0.0.0.
Note:
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.
