How to Forward Ports in Your Router for Synology CS407e

When you use a Synology CS407e device you might need to forward some ports in your router. By forwarding ports you allow connection requests coming from the internet to be directed to a Synology CS407e device.

Routers are not designed to allow incoming network requests. By forwarding ports you can work around this limitation.

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

• Your router's IP address.
• Your NAS's internal IP address.
• A list of 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.

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

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

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.

Port forwarding can also be set up step-by-step by hand. The step-by-step process for forwarding a port is:

• Log in to your router.
• Find the port forwarding section in your router.
• Put the IP address of your NAS in the proper box in your router.
• Enter the TCP and UDP ports that you need to forward for a Synology CS407e device in the corresponding boxes in your router.

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