Forward Ports on Your Router for Synology RS409

When you use a Synology RS409 device you may need to forward ports in your router. Forwarding ports is used to allow incoming connection requests from the internet to a Synology RS409 device.

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

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

• The IP address of your router.
• Your NAS's IP address.
• The TCP and UDP ports that need to be forwarded.

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's a part of the Network Utilities suite of tools and it's completely free to use.

We have a guide you can follow Find Your Router IP Address if you don't want to run the software.

The easiest way to forward your ports is to use our Network Utilities software. 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.

Alternatively you can do it by hand. The process for forwarding a port is:

• Log in to your router.
• Look for the port forwarding section in your router.
• Put the IP address of your NAS in the proper box in your router.
• It is now time to type the TCP and UDP ports that you are forwarding for a Synology RS409 device in the correct boxes in your router.

Frequently you have to reboot your router for the changes to take effect.
