DMZ
This feature, if enabled, allows one (1) computer on your LAN to be exposed to all users on the
Internet, allowing 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".
• The DMZ feature can be Enabled and Disabled on the Advanced Internet screen.
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.
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 re-
quested URL, the request is blocked.
• Enabling the URL Filter also affects the Internet Access Log. If Enabled, the "Destination"
field in the log will display the URL. Otherwise, it will display the IP Address.
• The URL Filter can be Enabled or Disabled on the Advanced Internet screen.
