Set Limits

Here you can create the policies to restrict the data limit, speed limit and Request limit.

The list of entries below is processed from top to down.

If more than one entry matches to single profile than entry having the lowest download transfer rate will be applied.

Each entry describes limitations on users for accessing content from the Internet.

Disable entries, to ignore limitations.

Every entry that matches the connection parameters specified in the entry are processed for that connection.

Example : If you create a policy as:

Download transfer limit:40M

Download rate :10K

Adjust transfer limit: per request

Then you are unable to download the files which are more than 40Mb and you are access the content from the internet with 10Kbps.

Profiles

Action

Select the appropriate action to apply when this entry matches.

Example : Select Allow if you desire to set a limit on data transfer or the number of requests that can be made. When limit is reached action will be denied automatically.

If action is set to deny then any request falling into the specified time range will be blocked, otherwise request is allowed.
