How to Open a Port in Your Router for Synology RS408

You may need to forward ports in your router when you use a Synology RS408 device. The purpose of forwarding ports is to make a direct connection from the internet to a Synology RS408 device.

Routers are not designed to allow incoming network requests. By forwarding a port you can overcome this limitation.

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

• Your router's IP address.
• Your NAS's IP address.
• 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.

You can run our free Router Detector software to locate your router's IP address. Our Router Detector tool is free to use and is part of our Network Utilities software.

Otherwise, you can follow our guide Find Your Router IP Address.

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.

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

• You can 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 that you are forwarding for a Synology RS408 device in the correct boxes in your router.

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