No. VPN and private networks are two different things:

Currently there is no firewall feature. Most likely you are looking to have one server being accessible to the internet while others are only part of the private network. In such cases please use the local firewalls of your operating system to turn off internet access for the chosen servers. In future Contabo will make a separate Firewall feature available.
