Opening a port refers to the process of configuring a network router or firewall to allow inbound connections from external sources to a specific device or service within a private network. It is a specialized skill typically performed by network administrators and security professionals, who must ensure that open ports do not expose the network or its devices to security risks or unauthorized access. Proper port configuration is essential in enabling remote access to network devices, allowing for effective communication between network devices, as well as optimizing network performance.
