I have a service running on a certain network server. In order to interface with that service, all the other network nodes contact the server on a particular open port (the service is listening on it).
For security reasons, I would like to not expose anymore the server with an open port but keep it to be accessible from the other nodes, by using something like a tunnel. Each node, then, should theoretically connect to a local port which is the listening point of the tunnel previously established by the server (contacting a dedicated node port).
I was thinking about something like stunnel but reading its documentation I got stuck and I am not sure it is what I am looking for. Is this particular setup possible? If yes, which tools do you suggest to use?
