Allowsconnection to a PPTP based Virtual Private Network (VPN).Hosting provided by SourceForge.LicensePPTP Client is licensed under the GNU General Public License (GPL) version 2 or later.PPTP Client was known as pptp-linux and was written by C. Scott Ananian.There have been many contributions by users of PPTP Client.PPP 2.4.2 and later contains MPPE support, added by Frank Cusack and others,that is licensed under a BSD without advertising clause license.The older and deprecated PPP-MPPE 2.4.0 and 2.4.1 contain MS-CHAP-v2and MPPE support that was added to PPP by Paul Cadach(paul@odt.east.telecom.kz). Two functions from OpenSSL were copied.
Because of this, we must say
for PPP-MPPE 2.4.0 and 2.4.1 that "this product includes cryptographic
software written by Eric A. Young (eay@cryptsoft.com)" and
"this product includes software developed by the
OpenSSL Project for use in the
OpenSSL Toolkit. (http://www.openssl.org/)."

Getting Started
So you'd like to run a PPTP tunnel from your Linux, FreeBSD,
NetBSD or OpenBSD system? Need to connect to your employer's
VPN? Just got ADSL? We suggest that you:
find documentation on our site that matches your distribution, or use
our generic instructions,
download and install the software according to the instructions,
refer to our Diagnosis HOWTO if
you experience problems,
join our mailing list and ask for help, and
contribute to the project by helping
us to improve the documentation or software.
Features
compatible with the Linux PPTP Server,
compatible with Microsoft Windows VPN Server,
compatible with many ADSL service providers,
compatible with Cisco PIX,
supports 128-bit stateless encryption using MPPE,
supports on-demand or persistent tunnels using pppd psuedo-tty support,
supports synchronous HDLC PPP encoding,
supports reordering of out of order packets,
runs on Linux, FreeBSD, NetBSD and OpenBSD.
Try it
Although we have some distribution specific HOWTOs in our documentation section, they all boil down
to these fundamental steps. To establish a tunnel to a PPTP server:
if your Linux kernel version is below 2.6.15, upgrade it or patch
it to add MPPE support,
if your Linux kernel does not have the ppp_mppe module, rebuild it
to add MPPE support, enabling the CONFIG_PPP_MPPE kernel build
option,
install the PPTP client, preferrably from your Linux
distribution,
if the version of pppd is below 2.4.2, upg
