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.
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
connection, and no connection currently exists, then this address will be blank or 0.0.0.0.
Type - Select the protocol (TCP or UDP) used when you receive data
from the special application or service. (Note: Some applications use
different protocols for outgoing and incoming data).
Start - Enter the beginning of the range of port numbers used by the
application server, for data you receive. If the application uses a single
port number, enter it in both the "Start" and "Finish" fields.
Finish - Enter the end of the range of port numbers used by the applica-
tion server, for data you receive.
Type - Select the protocol (TCP or UDP) used when you send data to
the remote system or service.
Start - Enter the beginning of the range of port numbers used by the
application server, for data you send to it. If the application uses a sin-
gle port number, enter it in both the "Start" and "Finish" fields.
Finish - Enter the end of the range of port numbers used by the applica-
tion server, for data you send to it. If the application uses a single port
number, enter it in both the "Start" and "Finish" fields.
If an application still cannot function correctly,
try using the "DMZ" feature.
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.
