Please make sure the following requirements are met:
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 L2TP 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 regular subscription. These features can be (de)activated later on as well.
Scroll down and generate the login and configuration data for the L2TP protocol. FYI: The Layer 2 Tunneling Protocol (L2TP) allows operations of multiple tunnels and can be considered as very safe. For authentication it uses PAP/CHAP, but it lacks its own encryption, which is why CyberGhost uses L2TP in connection with the encryption technology IPSec as 'L2TP/IPSec'
- Protocol: Choose the L2TP protocol.
- 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.
- 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 and Premium Server: This is the group of all paid service servers of the country chosen.
NoSpy Server: This is the group of all exclusive NoSpy servers of the country chosen. These servers can only be accessed by those subscribers, who opt for them as an additional feature.
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 server address of the country you want to surf from, e.g. '1-ro.cg-dialup.net'. The address includes encrypted information about your plan, the server group chosen and the domain name; the protocol to be used will be detected automatically when connecting to CyberGhost. If you want to connect to different locations, you need to adjust the target destination according to a different country and note down that 2nd, 3rd, 4th ... address as well.
- 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.
- Pre shared secret: For L2TP connections you also need this additional password.
You start your Windows protocol configuration by opening your 'Control Panel' and walk your way right to the 'Network and Sharing Center' ...
... where you click on 'Set up a new connection or network' ...
... and then 'Connect to a workplace'.
Next thing to do is to choose the option 'Use my Internet connection (VPN)'.
Add the server address you want to connect to, e.g. '1-ro.cg-dialup.net'. Furthermore type in a name for your new connection in the field 'Destination name'. If you plan to create more connections to different locations make sure, you label each connection thoroughly by adding the country name, eventually the server group and maybe even the protocol, so you can tell one from another, e. g. 'CG RO Premium L2TP'.
A native protocol connection addresses just one single server. If you want to surf from different locations, aka use different servers in different countries, you need to set up as many connections as locations you want (which means you have to do all steps again for each single country). If you want to be able to connect to five different countries, for example, you need to set up five different connections, from which you can choose later on.
When you're done, click on 'Create' and configure your new connection:
- Open 'Control Panel' and click on 'Network and Internet > Connect to a network'.
- Click on 'Change adapter settings' in the upper left of the window
- Right click on the connection you just created and choose 'Properties' from the context menu.
- A different window opens with an active tab called 'General', which displays the server address you entered before. Switch to the tab 'Security' and activate as the wanted 'Type of VPN' the entry 'Layer 2 Tunneling Protocol with IPSec'.
- As 'Data Encryption' you choose 'Maximum strength encryption', which equals 256 Bit AES. Note: For media streaming it might be necessary to choose 'Require encryption' (which equals 128 Bit AES) to avoid disruptions, caused by the big load the 'Maximum strength encryption' puts on your CPU.
- Also please click on the button 'Advanced Settings' and activate the option 'Use preshared key for authentication'. Enter 'CyberGhost' (case sensitive!).
Furthermore activate the option 'Allow these protocols' and put a mark in the box to 'Microsoft CHAP Version 2'.
Click on 'OK' to leave the dialog.
Click on the network symbol in the system tray and chose from the list of connections the one you just created.
Alternatively open 'Control Panel', click on 'Network and Internet > Connect to a network' and choose your created VPN connection. Double-click on it and click again on the respective connection in the Charms Bar.
Click on 'Connect' and enter your credentials, which consist of 1) the user name created in step 1, and 2) 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!
Certain routers need you to activate the L2TP/IPSec protocol in order to establish working connections. How you can accomplish that task should be documented in your router's manual.
