PPTP employs user level point-to-point protocol authentication
methods and microsoft point-to-point encryption (MPPE)
for data encryption

L2TP/IPSec employs user level PPP authentication methods over a
connection that is encrypted with IPSec

                  Recommended authentication method for VPN

Q

het verschil tussen PPTP en L2TP

A

L2TP encrypteerd meer in een pakket en beter

L2TP vereist computer certificates aan weerszijden van de connectie. Voor PPTP moeten client en server alleen het protocol ondersteunen

PPTP en L2TP hebben beide een beperkt aantal poorten nodig om door een firewall te geraken
