Ansible playbook to set up a L2TP/IPSEC VPN

People are asking for scripts to set up a VPN! This is even better, it is an Ansible playbook which sets up a L2TP/IPSEC VPN! The only thing you need to edit is the Shared Secret...

It sets up the VPN as described here: https://raymii.org/s/tutorials/IPSEC_L2TP_vpn_with_Ubuntu_12.04.html
It sets up local user authentication via PAM, so no passwords in text files. Tested and supported on Ubuntu 10.04+.

Read here how to set up Ansible, it is really simple and requires no additional software on your VPS (except Python)

Then, clone the repo and run the playbook:
https://github.com/RaymiiOrg/ansible/tree/master/vpn

ansible-playbook -s vpn.yml

(Don't forget to change the host and user)

You're all welcome.
