What is Port Forwarding?
Port forwarding is a network configuration method that enables you to direct internet traffic to a specific device or service within your local network. By opening certain ports, it allows external devices (like a friend’s computer) to access services on your network, improving connectivity and allowing specific activities like hosting a server or online gaming.
