Chapter 12 Content Filtering Screens Table 56 SECURITY > CONTENT FILTER > General LABEL DESCRIPTION Matched Web Pages Select Block to prevent users from accessing web pages that match the categories that you select below. When external database content filtering blocks access to a web page, it displays the denied access message that you configured in the CONTENT FILTER General screen along with the category of the blocked web page. Select Log to record attempts to access prohibited web pages. Unrated Web Pages Select Block to prevent users from accessing web pages that the external database content filtering has not categorized. When the external database content filtering blocks access to a web page, it displays the denied access message that you configured in the CONTENT FILTER General screen along with the category of the blocked web page. Select Log to record attempts to access web pages that are not categorized. When Content Filter Server Is Unavailable Select Block to block access to any requested web page if the external content filtering database is unavailable. The following are possible causes: There is no response from the external content filtering server within the time period specified in the Content Filter Server Unavailable Timeout field. The ZyWALL is not able to resolve the domain name of the external content filtering database. There is an error response from the external content filtering database. This can be caused by an expired content filtering registration (External content filtering's license key is invalid"). Select Log to record attempts to access web pages that occur when the external content filtering database is unavailable. Content Filter Server Unavailable Timeout Specify a number of seconds (1 to 30) for the ZyWALL to wait for a response from the external content filtering server. If there is still no response by the time this period expires, the ZyWALL blocks or allows access to the requested web page based on the setting in the Block When Content Filter Server Is Unavailable field.
