OpenVPN both as a server and as a client

Hello,
Is the following scenario possible?
Quote:

Outside Server (OpenVPN Server) ---> Intermediate Server (OpenVPN Client + OpenVPN Server) ---> Client (OpenVPN Client)

Clients must connect indirectly to the outside server. The intermediate server plays the role of OpenVPN client for the external server and OpenVPN server for the clients.

Thank you.
