To get a full understanding of how the device works, you first need to know the different ways you can access a Datto device and how each method differs.
In order to access your device, all networking needs to be properly configured. In Datto Networking Requirements, it lists the following requirements such as different firewall settings, ports, and the proper connection to the local network.
Once all networking requirements are met, there are three different ways to access your Datto device.
Accessing a Datto Device through the Remote Web
When accessing through the Remote Web, it's a connection in which you are able to modify general settings of the device. You are able to access the Remote Web through two different methods.
Accessing the Datto Device from the LAN
This method is used when you're on the local network. Typically, this method is quicker than accessing the Remote Web through a remote location. In Accessing a Datto Device Through Remote Web: LAN, it goes over the steps involved when accessing from the LAN.
Accessing the Datto Device from the Remote Location
This method is used when you're not on-site with the Datto device. When using this method, you must access the Partner Portal in order to get to the Remote Web. In Accessing a Datto Device Through Remote Web: Remote Location, it goes over the steps to access the Remote Web through a remote location.
Accessing a Datto Device through VNC
A Datto device can also be connected to through Virtual Networking Computing, also known as VNC. It is a service that functions similarly to Remote Desktop in which connects over port 5900.
The difference with this method is that once connected to VNC, you are able to access Remote Web, Virtual Box, and SSH all in one. In the article How to Connect to a Datto Device via VNC Locally and Remotely, describes how to download the VNC client and how to access the device either locally or remotely.
