Internet access restrictions

Let us consider the situation when it is necessary to open access to some websites (for example, www.google.com, www.yahoo.com) and close access to all the rest of the web resources.

To solve this problem we need to create a rule with the following parameters ( illustration):

• Object – Connection.
• Action – Close.
• On the fifth page of the dialogue window (Filters) in the URL list field add * as URL entry and list all the allowed websites as exceptions: *google.com*, *yahoo.com*.
• Apply the rule to all users.

To ban users' access to certain websites it is necessary to create a rule following the procedure described above. However in this case on the 'Filters' page of the dialogue window in the 'URL list' field enter all the forbidden websites as URL entries ( illustration).

It is possible import the forbidden sites list from a text file with *.flt extension. The file must be a regular text file with the masks of the forbidden sites listed one in a line.

To ban downloading files with a certain extension, create a new rule with the following parameters ( illustration):

• Object – Connection.
• Action – Close.
• On the 'Filters' page list all the forbidden file extensions in the URL list field, e.g. *.jpg*, *.jpeg*, *.gif*.
• In the drop-down list select 'Entire URL or Document address'.

The rule described above forbids downloading of graphic files.

To automatically close connection for users who reached a zero balance on their accounts it is necessary to enable the 'Activate tracking' option on the 'Limits' page of the rule setup dialogue window ( illustration). This rule will be closing connections.
