Hi, I prepare the server video, but what it's strange to me is the fact that after setup the tap settings in openvpn and save the changes I can't reach the trb141 via USB NDIS connection anymore. And I can't connect to the IP address of the webui of the router, the only thing to do is to reset to factory settings pushing the reset button. The server is a rut series too (rut905) and is already working with other 2 clients (trb140). Have you tried to save a tap openvpn settings to a trb141 router? Do you still have USB connection with the IP of the router?
