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 sites.
• 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.
