Forwarding Ports for a QNAP TS-121 device

When you use a QNAP TS-121 device you may need to forward ports in your router. The purpose of forwarding ports is to make a direct connection from the internet to a QNAP TS-121 device.

The internal IP address of your router.
Your NAS's IP address.
Each of the TCP and UDP ports that you need to forward.
