Windows 10 How to keep route alive using cellular (currently disconnecting when I connect ethernet)

[Ali Bhatti]

Hi,


I have a development board which is running windows 10 pro. On the board there are two Ethernet and Wi-Fi connections including 1 cellular.


On the other hand I have windows server. There is a VPN tunnel between cellular(dev board) and the server in Azure.


I am using SSH tunnel to rdp the dev board from the server mainly because rdp port is restricted on the server whereas SSH is available. This is again is only available when i have dev board running using cellular.


At the time when I have rdp running from server to the dev board, the only live connection is cellular and I have not connected the ethernet adapters or wi-fi. As soon as i connect the ethernet connection, the rdp drops and at this point i am able to ping the sim IP but not able to rdp. RDP comes up saying internal error. Which looks like something goes wrong when i have ethernet connected.


I want to get to the point where I use cellular to connect the dev board to the server. Run the rdp using the SSH tunnel. Connect the I/O to ethernet and not get disconnected on the rdp running.


There is no monitor on the dev board, so the only connection that i can make on the device is using either ethernet/Wi-Fi or cellular.


I am not using Ethernet for internet, but using for another interface.


I have tried giving the priority to the cellular, but it does not work.


I have tried to add some persistant route and it still does not work.


Please see below some details from the dev board when connected to the rdp session.
