NordVPN works on Synology devices through manual configuration. In other words, you'll get to pick a server from among the VPN's 6,300+ servers across 111 countries and configure a connection on your Synology NAS to that specific server. This will encrypt your incoming/outgoing traffic.

Note that NordVPN mentions Synology 5.1 and 6.1 software versions on its website, which are the most widely used versions at the moment. However, there's no official list of supported Synology NAS devices. That said, as long as your NAS supports VPNs, you should be able to configure NordVPN.

In this article, you'll learn how to configure NordVPN on Synology versions 5.1 and 6.1 with in-depth and thorough instructions.
