I have a server currently connecting to a pptp remote server.
This server(lns\lac) has the option for pptp connections and l2tp 
The l2tp connections are not using ipsec encryption at all.
I have seen couple guides\tutorials on the internet:
- https://wiki.archlinux.org/index.php/L2TP/IPsec_VPN_client_setup

But all the guides that I have found are using ipsec with "secret".
On ubuntu there is a gui applet that helps setting these kind of 
connections up but I am working with a CentOS server and not Ubuntu desktop.

If someone used l2tp the same way I want to use on CentOS 7 please give 
me some advice.

If you have a guide which might help me I will be more then happy to see 
this one.
