Answer 4

After creating an OpenVPN session, you will have a new interface and a pair of IP addresses - your own and that server. Next, you need route add ...the IP addresses of the PPTP server on this new interface or one of these IP addresses.
And you also need to make sure that the PPTP server has the correct addressing - your IP address (the one that is called "own" above) must be routed to the OpenVPN server.
