Which tunneling protocol should you use for VPN?

Virtual Private Networking in Microsoft Windows supports two tunneling protocols: L2TP and PPTP. Which VPN tunneling protocol should you use in which circumstance? Here’s a quick guide:

Use PPTP if your enterprise doesn’t have a CA to issue computer certificates and if you need compatibility with VPN client computers running legacy Windows platforms.

Use L2TP if your VPN connections require data integrity and non-reputability and not just the data confidentiality that PPTP provides.

Use PPTP if your VPN clients may be located behind NATs as most NATs can be configured to work with this protocol but not with L2TP.
