Answer 1

To the author - sorry, but the questions are not entirely clear, due to the fact that it is not clear what meaning you put into the definitions. VPN is a virtual private network. What is meant by your "virtual private network - server"? A remote server with which you can raise a VPN connection? If so, then - this is any VPS and, for example, OpenVPN as a service, on any axis ...
question b) - corny from the selected technology, the server connects to a remote server when it boots.
question c) - this must be done either on the server with the windows routing service (if I'm not mistaken), or on the router itself - depending on where your routing tables live.

Answer 2

1. Do not mix questions together. Do you seriously think that a person will answer "at the same time"?
2. The topology is unclear. How does this server go online and where are you going to deploy the VPN?

Answer 3

you can use the dynamic dns service to somehow solve the problem with dynamic ip and connect by ddns name to the host. In general, openvpn is easy to set up and should solve your problem.
