Instructions allow applications to communicate with each other via Windows Firewall

Windows Firewall acts as a barrier to prevent your computer from connecting to the rest of the Internet. The firewall retains unwanted network traffic and allows applications on your computer to communicate with the outside world. But each fence needs a gate, and that's where exceptions come in.

When you allow an application to communicate via a firewall, it is called exceptions. Windows creates exceptions for its own system services and applications, and when you install a new application that wants to communicate with the outside world, Windows will ask if you want to allow the application to communicate. or not?

2. Configure the Advanced Firewall Rules

Windows provides two different interfaces to work on the firewall. Setting up the Setting interface is the simplest way to allow an application to communicate.

However, there is another tool with many other installation options, Advanced Security.

You can set up this tool as follows:

• Not only does the rule govern traffic in and out of the application, but also creating Network Traffic is coming on a specific port.

• Network traffic directly to computers, especially on your local network based on applications or port numbers.

• Create connection security rules that force other computers to try to communicate with you, using different communication methods to establish their identity.

• Monitor the use of rules and other security connections.
