Setting Up a Port Forward for a QNAP TS-420 device

You may need to forward ports in your router when you use a QNAP TS-420 device. Forwarding ports is used to allow incoming connection requests from the internet to a QNAP TS-420 device.

Routers generally do not allow incoming connection requests from the internet. By forwarding a port you can overcome this limitation.

Before Forwarding a Port Checkoff This To Do List

Before forwarding a port make sure that you know these things:

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

Find the IP Address of Your Router

To find your router's IP address the easy way you can use our free Router Detector software. It's a part of the Network Utilities suite of tools and it's completely free to use.

If you do not want to run the software, you can follow our Find Your Router IP Address guide.

How To Forward Ports for a QNAP TS-420 device

We have Network Utilities software that can forward ports for you. Network Utilities lets you manage port forwards by putting them in when you need them and also removing the ones that you no longer need which maximized network security.

Another option is to go through the process of forwarding ports one step at a time. The normal process for forwarding a port is:

Start by logging in to your router.
Locate the section in your router that deals with port forwarding.
Put your NAS's IP address in the proper box in your router.
Put the TCP and UDP ports for a QNAP TS-420 device in the corresponding boxes in your router.

Usually you have to reboot your router in order to save the changes.
