Virtual Private Networks

PPTP VPNs Point-to-Point Tunneling Protocol (PPTP) – PPTP uses a control channel over TCP – PPTP was the first VPN protocol that was supported by Microsoft Dial-up Networking – Many security vulnerabilities found; no longer recommended by Microsoft

L2TP & SSL VPN’s Layer 2 Tunneling Protocol (L2TP) – VPN Concentrator (LAC) – LNS – Site-to-site VPN connection – Uses IPSec for security of connection

L2TP & SSL VPN’s SSL VPNs – Other options than PPTP and L2TP. OpenVPN Pure IPSec connections are possible. – Security encoded directly into application
