If you want to use the Open Telekom Cloud, you must first reserve a virtual IP address space on Telekom's physical servers. This private network area, which guarantees the privacy of users, is called the Virtual Private Cloud (VPC). No other customers of the Open Telekom Cloud have access to a virtual private cloud defined by you.

Installation of the Virtual Private Networks - how it works, step by step

Only when a VPC has been defined a VPN network can be set up with the Open Telekom Cloud. This enables, for example, the secure connection of the external company network to the virtual resources of the Open Telekom Cloud. To set up a Virtual Private Network, follow these steps:

1. Log into the Open Telekom Cloud console ein.

7. Set a pre-shared key as the password to gain access to the new VPN.
8. Now set the subnet mask that was created with the VPC.
9. Upon request, you can also set individual rules for the protocol at the end. For example, here you can select the encryption algorithm and set how long a key should be valid.

Important: Creating VPN settings also for servers apart from the Open Telekom Cloud

Your Virtual Private Network is now set up. In this way, you can easily integrate the Open Telekom Cloud into your corporate network. Important: In addition to the Open Telekom Cloud, if you use other servers whose communication with each other is to be ensured, the same VPN settings must also be set up on the respective servers. It is not enough to create the VPN exclusively in the Open Telekom Cloud!
