    What is port forwarding?

    ~15s
    Port forwarding tells your router to send specific internet traffic to a specific device on your network. Think of your router as a receptionist — port forwarding tells it "send gaming traffic to the PlayStation."

    When you need it

    ~15s
    Hosting a game server or Minecraft server. Running a home security camera accessible remotely. Hosting a website from home. Running remote desktop software. Most people never need port forwarding.

    How to set it up

    ~15s
    Log into your router (usually 192.168.1.1). Find Port Forwarding settings (under Advanced, NAT, or Firewall). Enter: the port number, the device's IP address, and the protocol (TCP, UDP, or both).

    Find common port numbers

    ~15s
    Minecraft: 25565. PlayStation: 3478-3480. Xbox: 3074. Web server: 80/443. Remote Desktop: 3389. Google "port forwarding [your game or app name]" for the specific ports needed.

    Security warning

    ~15s
    Port forwarding opens a door in your firewall. Only forward ports you actually need. Close them when you're done. Never forward ports for services you don't understand. Consider using a VPN as a safer alternative.
