Advanced Internet Screen

This screen provides access to the DMZ and URL Filter features.

DMZ

This feature, if enabled, allows one (1) computer on your LAN to be
exposed to all users on the Internet.
The DMZ feature 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 sent to
the corresponding IP address from the Internet.
• 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.

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:
• Never - disable this feature.
• By Schedule - block according to the settings on the Schedule page.
• Always - allow blocking all of the time, independent of 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.
