How to use our L2TP/IPSec (IKEv1)
Posted by Max Biggavelli on 13 August 2013 05:18
Since 19.11.2013 we have officially finished and implemented our L2TP/IPsec solution on ALL locations.

Lets dont waste anymore time and go into the setup procedure now!



Benefits of L2TP:

[+] All versions of Windows since 2000/XP and Mac OSX 10.3+ have built in support for L2TP/IPSec.

[+] Fast speed even while traffic still being encrypted (latest tests show slightly/notably better speed results compared to OpenVPN UDP and even more so over TCP!)

[+] Supports Portforwarding

[+] IPsec is a known secure standard and has shown no known critical vulnerabilities when used in conjunction with AES

[+] Using a mobile device with iOS (iPhone) or Android it is the fastest to setup and configure, as it is supported natively (no additional software required to install)

[+] IP change and Encryption for ALL Applications



Downsides of L2TP:

[-] L2TP/IPSec can be more "complex" than OpenVPN and more difficult to configure to work reliably between devices behind NAT routers. On the other hand, as long as both the server and client support NAT traversal, there should be no issues.
In the practice L2TP/IPSec has proven itself it to be as reliable and stable as OpenVPN is.




Connect details:

Hostname: uXXXXX.nvpn.so (your uXXXXX.nvpn.so hostname you can find in your .ovpn config file)

Username: Your VPN username

Password: Your VPN password

Pre shared Key: NVPN0PSK9

 

 

Setting up L2TP/IPsec on Windows 7 (any other windows version is similar):


1. Start off and click on the Start Menu and type “VPN” into the search box.

 

2. Enter your unique "uXXXXXX.nvpn.so" hostname in the Internet address field (you find your DNS hostname in your .ovpn config file!!) and set as Destination name "nVPN". Lastly, make sure that the checkbox labelled “Don’t connect now; just set it up so I can connect later” is checked. Then click the “Next” button.

When you click on “Connect to a network”, a list of Connections appears. Right click on the “nVPN” connection and choose “Properties”.

 

5. Choose type of VPN "Layer 2 Tunneling Protocol with IPsec (L2TP/IPsec)" and tick "Unencrypted password (PAP)".

Click on "Advanced settings" and choose “Use preshared key for authentication" and enter "NVPN0PSK9" into the textbox. Click the “OK” button.

Setting up L2TP/IPsec on Mac OS:

Open your Network Preferences, click on the [+] sign and choose "VPN", "L2TP over IPSec" and name it "nVPN - IKEv1".

Server Address: uXXXXX.nvpn.so (your uXXXXX.nvpn.so hostname you can find in your .ovpn config file)
Account Name: Your VPN username
click on "Authentication Settings":
Password: Your VPN password
Shared Secret: NVPN0PSK9
Important: click on "Advanced" and activate "Send all traffic over VPN connection".
Confirm your settings and click on "Apply", now click on "Connect".

 

 


Setting up L2TP/IPsec on Android:

The configuration instructions were created using a Samsung Galaxy S4 running Android 4.3 (Jellybean) but will work similar/identical on other previous versions as well!

Screen layout and configuration steps required may vary slightly between makes and models of device and version of Android installed.

From the home screen go to "Settings" -> "Wireless & Networks"  -> "More..." -> "VPN" -> "+"

Name: nVPN
Type: L2TP/IPsec PSK
Server address: uXXXXX.nvpn.so (your uXXXXX.nvpn.so hostname you can find in your .ovpn config file)
IPsec Pre-shared Key: NVPN0PSK9
DNS-servers: 8.8.8.8

Username: Your VPN username
Password: Your VPN password

 

 


Setting up L2TP/IPsec on iPhone/iPad (iOS):

From your Home screen go to "Settings" -> "General" -> "VPN" -> "Add VPN Configuration" -> "L2TP"

Description: nVPN
Server: uXXXXX.nvpn.so (your uXXXXX.nvpn.so hostname you can find in your .ovpn config file)
Account: Your VPN username
RSA-Secure ID: Off

Secret: NVPN0PSK9
Send all Traffic: On

To connect, save it and activate the "nVPN" connection.
