When using a native VPN protocol please make sure that your VPN protocol software supports the Internet protocol IPv6 along with IPv4 or run an IPv4 Internet connection only. Many Internet Service Providers connect with the IPv6 protocol or offer both protocols, IPv4 and IPv6, at the same time and as long as a native VPN protocol doesn't support IPv6 you risk data leaks, since an IPv6 connection can bypass the tunneled IPv4 connection.
While the CyberGhost client does support IPv6 and therefor prevent IPv6 leaks, users of native VPN protocols need to deactivate the IPv6 Internet protocol manually.
Disclaimer: Please keep in mind that, although the technical process is as thoroughly documented as possible, you need to have at least some technical understanding. There's always a chance for an overseen mistake and/or things have changed and the article is not updated yet.
Visit your CyberGhost VPN online account.
Click on the menu entry 'My Devices' and then on button 'Add Device'.
In the list of Operating Systems you can CyberGhost use with, please click on 'Other' to be able to setup all necessary options for the OpenVPN protocol. When done the screen extends and gives way to 'Create new credentials'. Do it by clicking on the respective button.
Scroll up the page. As you see, the placeholder for a new device is now replaced by 'Linux, Router, etc.'. Click on that button:
Type a name for your new device and activate the wanted extra features, provided with each Premium subscription:
Scroll down and generate the login and configuration data for the OpenVPN protocol:
- Protocol: Choose the OpenVPN protocol you want to use:
- OpenVPN (UDP): UDP allows higher speed than the TCP version, but can result in broken downloads in some cases. This is the default setting.
- OpenVPN (TCP): TCP allows more stable connections than the UDP version, but is a bit slower. Choose this version, if you have recurrent connection issues such as sudden disconnections.
- Country: Since native protocol connections may only be used with exactly one server you now have to choose the country you want to surf from; the server to be used in this country will be chosen by CyberGhost automatically. (If you want or need different PPTP, L2TP or OpenVPN connections in different countries, repeat all steps for every country.)
- Server group: Depending on the chosen country as well as the availability of different server types as an attribute of your current plan you can also define a server group to use:
- Standard Server: This is the group of all paid service servers (Special Edition, Premium, Premium Plus)
- Premium Server: This is the smaller group of all exclusive servers for Premium subscribers (Premium, Premium Plus)
- NoSpy Server: This is the group of all exclusive NoSpy servers for Premium subscribers with special extensions.
After setting up your connection wishes please note down the following data sets. You will need them to configure your device:
- Server: This is the address of the country (server) you want to be connected with, e.g. '1-ro.cg-dialup.net'. Note: This address changes with every country you have chosen in the step before. The actual single server to be used will be chosen automatically by CyberGhost.
- User name: A solely for protocol usage generated user name. This is NOT your regular CyberGhost account user name.
- Password: A solely for protocol usage generated password. This is NOT your regular CyberGhost account password.
Once done, please download the configuration file. For that please click on 'Download Configuration' and save the file on your computer. It's a ZIP file, which contains the following single configuration files:
- ca.crt: This is the certificate of the certification authority
- client.crt: This is the user certification file
- client.key: This is your private key file
- openvpn.ovpn: This is your OpenVPN configuration file
Save the file to your desktop.
Install OpenVPN and the network manager on Linux Ubuntu.
For that click on 'Menu > Search' and type 'Terminal' in the search field:
In the terminal window enter the following commands and confirm with 'Enter':
sudo apt-get update
sudo apt-get install openvpn
Start the file manager, open your home folder and create a sub-folder called 'CyberGhost'.
Unzip the content of the downloaded ZIP file and copy all single configuration files right inside that folder.
If you want to surf from different countries, rename the unzipped OpenVPN configuration file from 'openvpn.ovpn' to e.g. 'CG_RO_NoSpy.ovpn' (or whatever location/server group combination you have chosen while setting up the configuration file in your account management). Choose then a different location and a different server group (if available) and download the next zipped configuration file. Unzip it, rename the containing 'OpenVPN.ovpn' as well und copy it also inside the new folder. The also downloaded remaining certificate and key files in the ZIP do not need to be copied again, for you already have them from the first download.
For two different countries you need for example do the following steps:
Go back to the terminal window and start OpenVPN:
sudo openvpn --config
Don't push 'Enter' now, but instead move to the open CyberGhost folder, click on the wanted OpenVPN configuration file (e. g. 'openvpn.ovpn' or 'CG_DE_Default') and move it to the terminal window. The command line for OpenVPN will be completed automatically. Now you can push Enter'. (If you get an error message delete the quotation marks from the pathname of the configuration file.)
|Note: In case you receive an error message, saying 'No such file or directory', please first use the Terminal window to move to the directory with the configuration files. If for example the files are located in a folder called 'CG' on your desktop, you need to type 'cd desktop' and then 'cd CG'.|
The command now might look like this one:
sudo openvpn --config [pathname to file]
Enter your Ubuntu user password, then the user name created in step 1 and at last the password, also created in step 1. DO NOT use your regular CyberGhost user name and password, which you use to login in the client and your account management!
DON'T close the terminal window after the connection has been established. If it's in the way, just minimize it, but don't close for your connection will also be closed then.
If you want the window not just out of sight, but completely away, add a '&' to the OpenVPN command:
sudo openvpn --config [Pfadname zur Datei] &
This bans the process to the background and the terminal window can be closed after the connection has been established.
To end the VPN connection push 'CONTROL + C'.
