Forward Ports for a QNAP TS-420U device
You might need to forward some ports in your router when you use a QNAP TS-420U device. By forwarding ports you allow connection requests coming from the internet to be directed to a QNAP TS-420U device.
Routers generally do not allow incoming connection requests from the internet. By forwarding a port you can overcome this limitation.
Remember to Do These Things Before You Forward a Port
Before you can forward a port you need to know the following things:
