If you provider doesn’t grant you enough bandwidth, or if you want to limit speed for user to access to minor network resources, you can create a rule “speed limit”. In this case, choose “Add”→ “Speed limitat” in the tab “Rules and restrictions” either in the user settings or group settings.

It is a common practice, when user have high-priority traffic (for example, mail), and the rest of traffic (like ftp, or http traffic) should be restricted.

In the rule settings you can also indicate the direction of traffic that would be limited, protocol, port and time (in which limitation will be applied). There are three ways of applying the rule:

If you want to limit user speed even for the traffic that goes to ICS, not only through it, you can mark the special checkbox.

The “average speed” parameter is used only for connections that are going through the proxy-server. When you specify this speed, connections, that are smaller than this number (usually it means small web-pages), will remain their usual speed. And more heavy connections (often file downloading etc) will have the average speed.
