I know there are many tutorials on the net for setting up VPN client and server.
I you find one that is simple/short, I am interested only in the server part.
For client, I will use OS X so I prefer a solution that uses
L2TP over IPsec or
PPTP because I suppose Cisco IPsec would cost something.
I don't want to spent too many hours setting it up. You know, maybe someone already made a setup script 🙂
Note: I am using an EC2 micro instance running Ubuntu 12.04 on it.
