Intermediate VPN server?

Question

openvpn

The provider threw me behind NAT and OpenVPN + MS SSTP + L2TP/IPSec vpn servers stopped working! Recommend a free intermediate server with OpenVPN or L2TP / IPSec protocols, which will relay connections to the server and make Bridge to its network. The scheme is something like this - the client connects to the intermediate server and receives the network address of the main server behind NAT, as well as configurable access to its network. A program is installed on the client server (which is behind NAT), which connects it with an intermediate server. In this case, the main server in some cases has access to the network behind the client.

here is the diagram
