PPTP vs L2TP vs OpenVPN for VPN’s
Found an excellent comparison chart here:
Windows 7 – PPTP
Windows 7 uses PPTP – which only allows 1 tunnel. It’s not really designed for security. Try to avoid PPTP – as it’s very weak.
IPSEC v OpenVPN
The real contender is IPSEC v OpenVPN, and IPSEC is a compromise – it operates to the lowest common denominator, which is never a good idea. Security by committee pleases no-one.
OpenVPN. Open source that leads the way in security and privacy.
