How to set up L2TP/IPSec VPN on Ubuntu

Ubuntu has stopped shipping L2TP over IPSec support since Precise. A workaround for this exists using network-manager-l2tp.

In this tutorial we will show you how to set up L2TP/IPSec VPN on Ubuntu but first let’s see what are our requirements and recommendations.

Requirements

In order to set up the L2TP/IPSec VPN you will need:

  1. A CactusVPN account. If you don’t have one you can try our services for free.
  2. Your VPN username, password and VPN server address. You can find them in your account on our website, by going to Settings.

If you still want to set up L2TP/IPSec VPN manually, go step-by-step through following instructions:
