How to Port Forward QNAP TS-439U-SP in Your Router

When you use a QNAP TS-439U-SP device you may need to forward ports in your router. By forwarding ports you allow connection requests coming from the internet to be directed to a QNAP TS-439U-SP device.

Routers do not generally allow incoming connection requests from the internet. Forwarding ports can work around this limitation.

You need to know the following things before you can forward a port:

• The IP address of your router.
• The IP address of your NAS.
• The list of the TCP and UDP ports that you need to forward.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

When shopping for a VPN, make sure that they meet the following criteria:

• Your VPN provider should have a no-logs policy. This means that they do not keep any logs of any kind.
• Make sure that your VPN provider has lots of exit nodes all around the world.
• Check that your VPN will not affect your speed.
• Verify that your VPN provider uses WireGuard as the underlying protocol.
• Many people prefer a VPN provider that is not based in the United States.

This is the list of requirements that we used when we were shopping around for a VPN provider. There are lots of free, shady VPN providers out there that we looked at and dismissed.

Based in Panama, using diskless servers, and with over 6,100 servers in 61 countries, we can safely say that NordVPN satisfies all of these requirements.

Once you've set up your NordVPN account on multiple computers and enabled Meshnet, you can seamlessly access all of your devices as if they were on the same network. You don't even have to log in to your router. It's very simple.

We have free Router Detector software to help you find your router's IP address. It is part of our Network Utilities suite of tools and is free for you to use it.

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

You can use our Network Utilities software to automatically forward ports for you. Since Network Utilities allows you to both forward and un-forward ports easily you can keep your network security maximized, and then forward ports only when you need them.

You can also choose to set up port forwards manually. The step-by-step process for forwarding a port is:

• Begin by logging in to your router.
• Locate the section in your router that deals with port forwarding.
• Type your NAS's IP address into the correct box in your router.
• Put the TCP and UDP ports that you are forwarding for a QNAP TS-439U-SP device in the correct boxes in your router.

Some routers need to be rebooted in order for the changes to be saved.
