L2TP (VPN) for Linux Ubuntu
The difference lies in selecting L2TP with IPSec in the first prompt, so you should access a form dedicated to this technology where you can input the proxy.sh L2TP IP address, port and shared key ("security").
Then confirm and connect. Input your proxy.sh L2TP username and password where necessary and you should get successfully connected to the proxy.sh L2TP tunnels. Enjoy!
NB: If you encounter difficulties to connect with L2TP, please try to switch to OpenVPN. OpenVPN is more reliable, more secure and more flexible. OpenVPN also allows you to try various ports, including 'discreet' ones such as TCP 443. Below, you will find an aggregate of useful guides and articles that will help you troubleshoot your problems, should you have any.
