On the device you want to connect from, install the NoMachine client, the standalone component for starting remote access connections. It's free to use and you download the package suitable for your OS here:

There is also a NoMachine app for mobile which enables connections from iOS and Android devices. There is no limit on the number of outgoing "over-IP" connections you can start from any NoMachine client.

On the remote computer, be sure to install any of the NoMachine server products. Each installation needs a server license.
