Port Forwarding - How does it work and what are the benefits and risks
Here's how it works:
- IP Address and Ports: Every device connected to the internet has an IP address (like a street address) and uses ports (like house numbers) to manage different services.
- Router Role: Your router, which connects your home network to the internet, has a public IP address. Devices within your network have private IP addresses.
- Incoming Requests: When a device on the internet wants to access a service on your network (like a game server or a remote desktop), it sends a request to your public IP address.
- Port Forwarding Configuration: You set up port forwarding rules on your router, specifying that requests coming to a certain port on your public IP should be forwarded to a specific device (IP address) and port on your local network.
- Routing the Data: The router then directs the incoming data to the correct device and port, allowing external devices to communicate with the designated service on your network.
Port forwarding will only work on the 3Gbps and 3Gbps Premium packages as you will be allocated a dynamic IP address.
Benefits:
- Remote Access: Allows you to access devices and services in your home network from anywhere on the internet.
- Gaming: Enables hosting game servers and ensuring other players can connect to your game.
- Security Cameras: Lets you view security camera feeds remotely.
Risks:
- Security: Opening ports can expose your network to potential attacks. It's essential to secure services and keep software updated.
- Complexity: Configuring port forwarding requires some technical knowledge about networking and IP addresses.
