How to allow communication for a certain application

If a new connection is detected in interactive mode and if there is no matching rule, you will be prompted to allow or deny the connection. If you want ESET Endpoint Security to perform the same action every time the application attempts to establish a connection, select the Remember action (create rule) check box.

You can create new firewall rules for applications before they are detected by ESET Endpoint Security in the firewall setup window, open the main program window > Setup > Network > Firewall > click the cogwheel > Configure > Advanced > Rules by clicking Edit.

Click Add to add the rule. In the General tab, type the name, direction and communication protocol for the rule. This window enables you to define the action to be taken when the rule is applied.

Type the path to the application's executable and the local communication port in the Local tab. Click the Remote tab to type the remote address and port (if applicable). The newly-created rule will be applied as soon as the application tries to communicate again.
