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

  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.
