How to enable the Firewall (Windows / MacOS)

The firewall helps protect the device by monitoring incomming and outgoing network traffic. Firewalls serve as a first line of defense in network security, establishing a barrier between trusted internal networks and untrusted external networks, such as the Internet. Newer devices tend to come with the firewall turned off. To ensure the firewall is on so it can do its work follow the following steps below.
