-A technology for creating Virtual Private Networks (VPNs) , developed jointly by MicrosoftCorporation, U.S. Robotics, and several remote access vendor companies, known collectively as the
[PPTP] Forum. A [VPN
] is a private network of computers that uses the public Internet to connect some nodes. Because the Internet is essentially an open network, the Point-to-Point Tunneling Protocol (
[PPTP
]) is used to ensure
that messages transmitted from one VPN node to another are "
secure"
. With [PPTP], users can dial in to their corporate network via the Internet.

It starts a pppd in the correct place; you might be interested in the [MPPE] patches.

-For firewalling interests.
PPTP uses [GRE] packets (protol 47) and a [TCP] connection on port 1723 for control. Most FireWall/[NAT] implementations don't understand the GRE connection identifier and thus will only support one PPTP connection, to a single PPTP server, when your connection is over NAT. Linux 2.4 doesn't seem
to have this problem
