How do I create a firewall rule to allow/disallow use of a certain application in ESET Cyber Security Pro?

Issue

  • An application (for example iTunes) is not working or having connectivity issues after installing ESET Cyber Security Pro
  • You want to configure the ESET firewall to block incoming or outgoing Internet communications for a specific application 

Details

The ESET Personal firewall acts as a network traffic filter that regulates communication within the local network or Internet. Using predefined rules, the Personal firewall analyzes network communication and decides whether or not to allow it. You can configure your Personal firewall to make exceptions for or to block certain applications.

Solution

  1. Allow an application
  2. Block an application

For example purposes!

The examples in sections I and II demonstrate how to create a rule to allow all online communications for iTunes or deny all online communications for iTunes. Creating these two rules in an actual network environment would cause them to cancel each other out.

  8. Configure the Protocol and Port settings. To create a rule to always allow the application, select TCP & UDP from the Protocol drop-down menu, select Both from the Ports drop-down menu and then select All from the Local Port and Remote Port drop-down menus. You can achieve more custom rules using different combinations of the Protocol and Port settings. Once you are finished, click Next

  9. In the Destination window you can define whether your rule applies for the entire Internet, for your local network, for a specific subnet or for a specific IP address or range of IP addresses. Select Entire Internet to create a rule to always allow the application. Click Finish when you are done making changes to create your new rule, and then close the Firewall window to return to the main program window.
