• URL Filter

URL (Uniform Resource Locator – e.g. an address in the form of

http://www.pentagram.eu or http://www.example.com) filter rules allow you to prevent

users on your network from accessing particular websites from their URL. There are no

pre-defined URL filter rules; you can add filter rules to meet your requirements.

Active – Select Yes from the drop down list box to enable or disable the URL Filter

feature.

Always Block – Select to always check URL filter rules (i.e. at all hours of the day).

Block from – Specify the time period to check 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 is checked to see if any

keywords are present in URLs accessed to determine if the connection attempt should be

blocked. Note that the URL filter blocks web browser (HTTP) connection attempts using

port 80 only. For example, the URL http://www.abc.com/abcde.html would be dropped

since the keyword “abcde” occurs in the URL.
