Advanced Features
•
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".
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.
Special Applications
If you use Internet applications which use non-standard connections or port numbers, you may
find that they do not function correctly because they are blocked by the Wireless Router's
firewall. In this case, you can define the application as a "Special Application".
The Special Applications screen can be reached by clicking the Special Applications button on
the Internet screen.
You can then define your Special Applications. You will need detailed information about the
application; this is normally available from the supplier of the application.
Also, note that the terms "Incoming" and "Outgoing" on this screen refer to traffic from the
client (PC) viewpoint

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.
URL Filter
If you want to limit access to certain sites on the Internet, you can use this feature. The URL
filter will check each Web site access. If the address, or part of the address, is included in the
block site list, access will be denied.
On the Advanced Internet screen, select the desired setting:
•
Disable - disable this feature.
•
Block Always - allow blocking all of the time, independent of the Schedule page.
•
Block By Schedule - block according to the settings on the Schedule page.
Click the Configure URL Filter button to open the URL Filter screen, allowing you to create
or modify the filter strings which determine which sites will be blocked.
The URL Filter screen is displayed when the Configure URL Filter button on the Advanced
Internet screen is clicked.
