NDIS connection gets disabled by Endpoint when VPN connected

[stallwoodj]

Hi,

We have a customer with Harmony E87 for Windows, who is using an application on their Android device via USB cable.

All is well while they are disconnected from Remote Access, but as soon as they connect to corporate VPN, the USB connection is shut down (specifically, it loses its IP address).

Is there an easy resolution for this? (NB as the corporate firewall is managed by Smart-1 Cloud we don't have access to the Trac TTM)

Thanks,Jamie

I don't believe you need to edit this on the management, but rather on the gateway itself.
