Forwarding Ports for a QNAP TS-451 device
You might need to forward some ports in your router when you use a QNAP TS-451 device. The purpose of forwarding ports is to make a direct connection from the internet to a QNAP TS-451 device.
By default routers do not allow incoming network requests. Forwarding ports can work around this limitation.
Remember to Do These Things Before You Forward a Port
Make sure that you know these things before forwarding a port:
- Your router's internal IP address.
- Your NAS's internal IP address.
- A list of TCP and UDP ports that need to be forwarded.
