URL Filter
URL (Uniform Resource Locator – e.g. an address in the form of http://www.billion.com or
http://www.example.com) filter rules allow you to prevent users on your network from
accessing particular websites by their URL. There are no pre-defined URL filter rules; you
can add filter rules to meet your requirements.
Enable/Disable: To enable or disable URL Filter feature.
Always Block: Select to always check the URL filter rules (i.e. at all hours of the day).
Block from: Specify the time period to check the URL filter rules (e.g. during work hours).
Keywords Filtering: Allows blocking by specific keywords within a particular URL rather
than having to specify a complete URL (e.g. to block any image called “advertisement.gif”).
When enabled, your specified keywords list will be checked to see if any keywords are
present in URLs accessed to determine if the connection attempt should be blocked.
Please note that the URL filter blocks web browser (HTTP) connection attempts using port
80 only.
For example, if the URL is
http://www.abc.com/abcde.html, it will be dropped as the
keyword “abcde” occurs in the URL.
