PPTP and L2TP VPN
You can use PPTP and L2TP to create a virtual private network (VPN) between a
remote client computer that is running Windows and your internal network. Because
PPTP and L2TP are supported by Windows you do not require third-party software on
the client computer. Provided your ISP supports PPTP and L2TP connections, you
can create a secure connection by making some configuration changes to the client
computer and the FortiGate unit.
This chapter provides an overview of how to configure FortiGate PPTP and L2TP
VPN. For a complete description of FortiGate PPTP and L2TP, see the FortiGate VPN
Guide.

Configuring PPTP
Point-to-Point protocol (PPTP) packages data within PPP packets and then
encapsulates the PPP packets within IP packets for transmission through a VPN
tunnel.
