The computers are not in the same network, neither has a public IP address, both connect to the Internet through a router/NAT – a direct connection is not possible, a UDP connection or a connection through the Tunnel Server is used: The computers have direct network visibility within a local network (Ethernet, Wi-Fi) – a direct connection is possible: means a connection through the Tunnel Server:.There is also a status string for every device, by which you can tell the mode of the connection currently established to it: a gray icon – the computer is currently offline:.a yellow icon means a direct connection with a specified computer is not possible:.a green icon indicates that your computer and a specific remote computer “see” each other over the network in at least one direction and can establish a direct connection:.a yellow icon indicates that you do not have a public IP and that your computer is not “visible” from the Internet:.an IP address, by which your computer can be uniquely identified on the Internet), which allows remote computers to connect to you directly: a green icon means that you have a public IP address (i.e.Next to every computer’s name, there is an icon that represents its current network availability: Opening FlexiHub, you see a list of computers currently logged in to your account: the first on the list is your computer, the rest – remote computers. UDP and Tunnel Server connections are markedly slower but come to the rescue when direct connection is not possible, for instance when both computers are behind NAT.

In terms of speed, a direct connection is always the fastest. The optimal connection mode is selected automatically, with the following precedence: direct connection → RDP connection → UDP connection → Tunnel Server connection.

Thus, it is useful to know what connection modes FlexiHub comes equipped with, how they compare in terms of speed, and how to always get the best performance regardless of what network connection you are on. While this usually isn’t particularly important for COM port devices, USB devices normally generate a much larger amount of traffic and, therefore, available network throughput significantly impacts the overall user experience while working with a device remotely. The connection mode used determines the speed of data exchange with a device.
