Visit your CyberGhost VPN online account and login with your Premium Username and Password
Click on 'My Devices' then 'Other'
Click Configure new device and now create your server configuration, as described below :
- Protocol : OpenVPN
- Country : Since native protocol connections can only be used with a single server, you must now choose the country from which you want to surf; the server to be used in this country will be automatically chosen by CyberGhost.
- Server Group : Select the available server group from the list.
OpenVPN UDP allows higher speed than the TCP version but can result in broken downloads in some cases. This is the default setting.
OpenVPN 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.
Once the desired parameters are chosen, save them with « Save Configuration »
To view the OpenVPN credentials that are generated for you on the configuration dashboard, press View Configuration.
After setting up your connection preferences, please take note of the following :
- Server Group : This is the address of the country (server) you want to be connected with, e.g. '12345-1-ca.cg-dialup.net'. 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 this protocol generated user name. This is NOT your regular CyberGhost account user name, it's used only to authenticate with our servers via Manual Configurations.
- Password : A solely for protocol usage generated password. This is NOT your regular CyberGhost account password, it's used only to authenticate with our servers via Manual Configurations.
- Pre-Shared Key
Once done, please download the configuration file. For that click on « Download Configuration » and download the config file to your computer (it's recommended that you create a special folder for the config, somewhere accessible like your Desktop and Extract/Copy the contents of the .zip file there.
Important : please keep your username and password obtained during the configuration process at hand, you will need them later in the setup.
Now, the saved config is a ZIP file, which contains the following single 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
If you need to change the country you connect to, you must re-configure the location to use in your account management and download the new zipped config file.
Unzip all containing files, rename the file 'openvpn.ovpn' to e. g. ‘CG_RO.conf’ (depends on the location you want to connect to) and copy all files into your OpenVPN directory on your Raspi. For that first move to the folder in which you unzipped all files by typing:
cd [path to configuration folder]
Now copy them:
sudo cp CG_XX.conf /etc/openvpn/
sudo cp ca.crt /etc/openvpn/
sudo cp client.crt /etc/openvpn/
sudo cp client.key /etc/openvpn/
If you want to surf from more than one country, download after the selection of a different country in your account management the next zipped configuration file and rename the new 'openvpn.ovpn' to 'CG_AnotherCountry.conf'.
For two different countries you need for example do the following steps:
- Specify device, protocol and operating system
- Choose a country, e.g. USA
- Download the zipped configuration file with certificates, key and OpenVPN configuration file
- Unzip the downloaded file and copy all files in your OpenVPN configuration folder
- Rename the OpenVPN configuration file from ‘openvpn.ovpn’ to ‘CG_USA.conf’.
- Choose the next country, e.g. Romania
- Download the next zipped configuration file
- Unzip the downloaded file and copy just the file 'openvpn.ovpn' into the configuration folder
- Rename it to ‘CG_RO.ovpn’.
- etc. ...
Make sure you have the right packages: Before you can begin configuring your network settings make sure you already installed the needed packages and have an up to date system:
Download the package information by opening a console and typing :
sudo apt-get update && sudo apt-get upgrade
Once done download the needed OpenVPN package with :
sudo apt-get install openvpn openssl openresolv
To be able to log in automatically, save your user name and password in a file called ‘user.txt’ and store it in your OpenVPN folder. For that first move to the respective folder:
Enter the following command to create and open a text file called 'user':
sudo nano user.txt
Type in your credentials (one in each line). In the first line type in the user name created in step 1, in the second line the password, also created in step 1, both as displayed in your account management when setting up a connection:
#First line is a generated username and the second line is a generated password.
DO NOT use your regular CyberGhost user name and password, which you use to login in the client and your account management!
Save your changes with ‘CTRL+O’ and leave the editor via ‘CTRL+X’
Next, open the configuration file ‘CG_XX.conf’ by typing
sudo nano CG_XX.conf
Extend the line ‘auth-user-pass’ …
… with the path to your credential file:
At the bottom of the configuration passage (after 'verb 4') add the following two lines:
Save via ‘CTRL+O’ and leave the editor with ‘CTRL+X’.
Then get the file autoloaded by typing :
sudo nano /etc/default/openvpn
and adding the following line:
AUTOSTART="CG_XX" (the name of the file WITHOUT the file extension ‘.conf’)
Again, save with ‘CTRL+O’ and leave the editor with ‘CTRL+X’.
At last type in your console :
sudo update-rc.d openvpn enable
Before starting OpenVPN check your configuration with …
… and have a look, if the last line (‘nameserver’) shows the IP of the router. If not, change it.
Now start OpenVPN:
sudo service openvpn start
Wait a few seconds and then test, if everything works fine.
Furthermore, you might want to open the website https://dnsleaktest.com/ and test on leaks. For that choose ‘Standard Test’ or ‘Extended Test’.
