Currently i have a server that is available via remote desktop by NATing an external ip to and internal ip on RDP port. I want to kill this connection and use something more secure like setting up a vpn server. I am able to setup PPTP but i want to take it a step further as i've read pptp is not very secure. Do any of you have suggestions? I am trying to figure out openvpn and L2TP but so far i've had no luck.
