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.
Multi-DMZ
This feature, if enabled, allows one (1) or more computers on your LAN to be exposed to all users on the Internet. You
can set a DMZ PC for each WAN IP address. If you only have 1 WAN IP addresses, only 1 DMZ PC can be used.
This allows 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".
To use more than one (1) DMZ, your ISP must assign multiple fixed IP addresses to you. You must enter each IP
address; you can then assign a DMZ PC for each IP address.
URL Filter
The URL Filter allows you to block access to undesirable Web site
To use this feature, you must define "filter strings". If the "filter string" appears in a requested URL, the request is
blocked.
Enter a descriptive name to identify this Special Application.
Type - Select the protocol (TCP or UDP) used when you receive
data from the special application or service. (Note: Some applica-
tions 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
application 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 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
application 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.
