The Rule is just a rule which tell NetLimiter what to do with selected Filter. Currently, there are three rule types available: Limit, Firewall and Priority.

To create a Rule you need to run Rule Editor which you can do by clicking on the selected Filter in Activity Tab or make it from scratch Rules tab and selecting Add rule.

Rule Editor

There are several options to choose from:

  • Filter: Select from list of Filters to which one will be the Rule applied.
  • Zone: Select a Zone for which will be the Rule applied. If you leave it blank then the Rule will work for all Zones.
  • Rule Type: Limit, Firewall, Quota and Priority are available.
  • Direction: There are three options: In, Out and Both, but they have different meaning for Limit and Firewall rule. When the Rule Type of the Rule is Firewall then the Direction represent how it originates. If you selected Limit then the Direction means the way the data flows (from or to your machine). Use Both if want to differentiate between In and Out.
  • Per-Type: Only available for Limits. If you select Per-Connection or Per-Process then the Limit will not be applied to the selected Filter as a whole, but same Limit will be applied to every Connection or Process which fall under the Filter.
  • Value: For Limits it represents maximum transfer speed which will be allowed for selected Filter and given direction. For Firewall there are three possibilities: Ask, Allow and Deny. If you choose Ask then you will asked how to handle a every connection for the Filter and chosen Direction. If you choose Allow then the connection will be allowed to be created and if you select Deny then every the connection will be blocked. For Priority, there are 4 levels to choose from.
  • Enabled: If leave it unchecked the Rule will be inactive and not working. It is just a simple tools which will allow you to quickly switch any Rule ON and OFF.


This simple tool allows you to schedule - Stop, Start, etc. - any rules based on a time condition. Just use it to specify time when the rule should be ON or OFF.
