4.1.4 PPTP
Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. PPTP
uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets. It is a client-server
based technology. There are various levels of authentication and encryption for PPTP tunneling, usually
natively as standard features of the Windows PPTP stack. The security gateway can only play "PPTP Client"
role for a PPTP VPN tunnel. PPTP tunnel process is nearly the same as L2TP.
PPTP Client: It can be mobile users or gateways in remote offices with dynamic IP. To setup tunnel, it
should get “user name”, “password” and server’s global IP. In addition, it is required to identify the
operation mode for each tunnel as main connection, failover for another tunnel to increase overall
bandwidth. It needs to decide “Default Gateway” or “Remote Subnet” for packet flow. Moreover, you can
also define what kind of traffics will pass through the PPTP tunnel in the “Default Gateway / Remote
Subnet” parameter.
