Internet Blocking at the Client

Configure Computers

Internet blocking (filtering) allows you to enforce Internet use policy by preventing users from accessing all or portions of the Internet.

Block vs. Allow

When you block users from the Internet, they cannot display the web page at the domain that is blocked, communicate at the port that is blocked, or communicate with a Chat/IM contact who is blocked.

Alternatively, you can allow users access to ONLY the web sites, Chat/IM, and other communication ports that you specify and no others. For example, you could limit Internet access to ONLY online references, a work-related web server, a specific FTP domain, in-house MSN messaging, and that's it.

Types of Blocking

Types of blocking available through Client Settings are:

Block Internet access and types of Chat/IM at the port. More...
Block during specific times (hour and day). More...
Local Web Site Blocking by domain. More...
Block Chat or Instant Message communication with specific contacts. More...
Block the Internet for specific users. More...

The most restrictive policy always applies
For example, if you BLOCK a list of web sites and all HTTP/HTTPS ports, NO web site access will be allowed because blocking the port is more restrictive. However, if you ALLOW only a few specific web site domains, you will effectively block chat and messaging communication (at the domain) even though the Chat/IM port is permitted. In this case, the domain blocking is more restrictive.
