A firewall is a device that protects computer networks from unauthorized access by restricting traffic to and from specific ports on the network. Firewalls can be configured to block all traffic, allow specific types of traffic, or allow specific applications to pass through.
Configuring a basic firewall involves setting up rules to allow or block specific types of traffic. Rules can be based on the source and destination address, the port number, or the protocol.
Rules can also be set to allow or deny traffic based on the application or type of traffic.
A firewall can be a valuable security tool, but it is important to configure it correctly in order to protect your computer network from unauthorized access.
