I have a server inside my lan. It runs owncloud and some applications for development purposes: docker, wildfly, tomcat, samba ... My workflow: I use a openvpn appliance to get inside my lan and then develop on the server.
I really like to remove the server from my flat. So I was thinking about renting a dedicated server. How would you setup such a single machine? I do not want any other application to be accessible from the outside, except openvpn and ssh.
It is the utter most importance, that nobody except me accesses any applications/files on the server. Sadly I do not have the funds, to pay for a separate vpn/firefall server and a dedicated machine. I can afford only a single server.
Would you run a vm on the server? I simple do not know what the best practice for such scenario is.
Server: 16GB Ram, Quadcore and a lot of space
My knowledge: Linux as Server and Desktop. Ubuntu Server would be my primary choice as an host os.
Edit 1:
I have the following setup at home: I have a router, which forwards a single port to the openvpn appliance. When I connect to it I have full access to my network at home and to the server on which I develop. I do not need to worry about any open ports on the server because, nobody ouside my lan can access it anyway.
If I rent a single server on the internet, everybody can access it. As a production machine I would simply close all the ports except (in a webserver) 80 and 443. Then everybody could only acces the http server and that's that.
My main problem: I want to access all ports on the development machine, which resides on the internet, but I do not want any other to be able to access it. Maybe I am just thinking about it wrong...
