18.3 PPTP

The Point-to-Point Tunnelling Protocol (=PPTP) can be used to set up an encrypted PPTP
tunnel to provide security for data traffic over an existing IP connection.
First a connection to an ISP (=Internet Service Provider) is set up at both sites. Once these
connections are available, a tunnel is set up to the PPTP partner over the Internet using
PPTP.
The PPTP subsystem sets up a control connection between the endpoints of the tunnel.
This is used to send control data to set up, keep alive and terminate the connection
between the two PPTP tunnel end-points. As soon as this control connection is set up, the
PPTP transfers the traffic data packed in GRE packets (GRE = Generic Routing Encapsu-
lation).
