Windows 10 VPN only works while TeamViewer is connected

Hey guys,

I have a strange case in which the standard VPN-Connection of an employee isn't connecting. Most of the time, the employee is working with our customers, so I used TeamViewer to have a look at the settings of the VPN. Case is: when the TeamViewer-Session is running, the VPN (L2TPD, IPsec) connects to our endpoint like a charm. When I disconnect TV, the VPN isn't connecting at all again.

What could be the cause here? Is TV routing the Windows-VPN? I disabled the Windows-Firewall too, but couldn't achieve any success either.

Thanks for help in advance!

Got it solved, seems like TeamViewer starts the IPsec-Policy Service. This service was set to "manual". Set it to "automatic", restarted the device and the VPN connects. In addition, the IKE-Service must be up and running, too. Hth someone, someday. :-)
