Description: Port forwarding is the process of allowing network traffic through a specific port on a device within a network, such as a router or a server. Each port on a device can be considered as an entry point for different types of network traffic. When a port is closed, traffic destined for that port is blocked, which can be useful for protecting the device from unauthorized access. However, in many situations, it is necessary to open certain ports to allow specific applications or services to function properly. For example, if you want to access a web server, you need to open port 80 (HTTP) or port 443 (HTTPS). Port opening can be done through the firewall settings of the operating system or the router, and it is a fundamental aspect of network management, as it allows control over incoming and outgoing traffic, as well as the security of devices connected to the network.
