Some time ago, we bought FLEX 6500 and console Maestro (OK1DVM, OK1DIG and me - OK1YA). Because FlexRadio, Maestro, and SmartSDR communicate only via local (LAN) network, we immediately began to create a VPN connection that would be suitable for remote connections over WAN. The result of our efforts and testing is a very small, compact hardware device (comprising the VPN Server and VPN Client), which offers many options for configuration,enabling a reliable,secure connection to the home LAN network and facilitating working remotely over the Internet anywhere in the world. Own public IP address is a condition for work with the VPN server.
The VPN server is usually placed on the same side where FLEXRadio (family 6000) is connected. The server is typically installed on a PC, which is constantly turned on, but from the point of view of the usage, size, and reliability it does not seem to be the best solution. In our case, the VPN server and VPN Client are installed in small boxes (12x10x3cm) with low power consumption - abt. 3W. Some ways of connecting the VPN server into the network may require a small and simple change in setup of the router (for instance, when the VPN server is connected into the local LAN behind the home router). Another option is to implement the home router setup directly into the VPN server.
On the remote side, the Internet is connected to the WAN port of the VPN Client via a UTP cable or via WiFi (optional). The speed of the Internet connection should be at least 1.5 MB/s. A public IP address is not necessary. Maestro or a laptop with SmartSDR can be connected to the output port of the VPN Client either via UTP cable or via WiFi. You can also connect laptop with some SW into the VPN client, for example, to switch FLEXRadio remotely on/off , to control the rotators etc.
The configuration of the VPN Server and VPN Client can be pre-set in accordance with user requirements.
I currently have a few sets of hardware (VPN Server and VPN Client) at the price of 150 Euro ($165 USD) per set and other hardware for remote work.
