BlockerFriday, January 29, 2016 10:13:31 AM
Blocker can be also viewed as a simple firewall. It is a tool which allows you to specify which application can connect to internet and which can not. You can also specify various conditions under which would any connections be allowed and other denied.
How to block an app?
In order to work, Blocker must be enabled. There are 3 places in NetLimiter where you can do it:
- At top of the Main window check
- Go to
- From main NetLimiter screen go to the Blocker and click on
Blocker is disabledbutton (it should switch to
Blocker is enabled).
Default blocker settings are located at
Tools->Options...->Service->Blocker. There you can select which blocker action will performed by default.
There are 3 types of actions from which you have to choose when creating a blocker rule. These are:
Deny: All connections for specified filter or application will be blocked.
Allow: All connections will be allowed.
Ask: When a connection for specified filter or application is about to be created an interactive window will pop-up. There you can decide which action should be taken upon particular connection.
(introduced in version 4.0.54)
Each Blocker rule is assigned a weight. The higher the value is, the rule is more important. If you have created two different Blocker rules for an app (or filter), then the rule with higher weight is applied.
You don't have to set weights for each newly created blocker rule. They are set automatically based on a filter for which they are used. The default weights are assigned in this manner:
A custom weight (bigger than 3) can be created using Rule Editor.
Whole machine (weight 1) < Zone(2) < Application/Network/Custom Filter (3) < Custom weights (4 and bigger)
