What Is Port Forwarding?

Port forwarding is a networking configuration that directs external traffic to a specific device inside your local network.

Example use cases:

• Hosting a Minecraft or game server

• Remote desktop access

• Running a web server

• Security camera access

• VoIP or VPN configuration

• Testing SaaS development environments

Without port forwarding, external requests cannot reach internal devices behind your router firewall.
