Establishing a VPN connection once I'm in a RDP session

I'm currently running a virtual machine with Windows 10. A connect to this virtual machine trough Remote Desktop Protocol. Once connected I want to establish a VPN connection to another server, but Windows forbidens me of doing that based on some security policy. If I access the virtual machine's console directly I can establish the VPN. Can you help me find out how to change this security policy so I can establish VPN connections when I'm a RDP? Maybe there is something in Windows registry I could change in order to achieve that.

I'm using a Cisco VPN client, but I guess the problem would occur no matter which VPN client I tried to use. My currentlu workaround solution is to go to my VM server (Proxmox), access the VMs console directly, than establish the VPN connection through there and once the VPN is established I can connect to the VM with RDP. The VPN connection will not break, so I guess this security policy is applied only at the very moment the VPN is being established...

Tried to find something in gpedit.exe, but couldn't...

Thank you.

 

Can't establish VPN connection to my office


I've upgraded both my laptop and my desktop in my office to Windows 10 Pro (both were coming from Windows 8.1).

VPN was working perfect before the upgrade.

At current I can't establish a VPN connection to my office.

The VPN server (at my office) is listening to port 3390.
Checking with netstat and port scanner, the port (3390) is opened.

On the VPN client I'm typing server IP:3390 but getting an error message saying "the remote connection was not made because the name of the remote server did not resolve).

Using just my server IP, I'm getting "verifying your connection info", and then "connecting to server IP".... and.. nothing more. It never connects.

Any help would be very appreciated.
