PPTP Point-to-Point Tunnel Protocol: Chapter 11. VPN Technologies, Tunnel Interfaces, and Architectures: Integrated cisco and unix network architectures: Networking: eTutorials.org.
PPTP is deprecated, and Microsoft has moved on to L2TP/IPSec as a strategic technology. Many documents, recipes, and configurations are available with regard to PPTP setups involving Microsoft clients and RAS servers and for PPTP configurations in context with DSL setups, which are common in some European countries.
Which is the Best VPN Protocol? PPTP vs. OpenVPN vs. L2TP/IPsec vs. SSTP. Facebook Icon. Instagram Icon. Twitter Icon. LinkedIn Icon.
In Summary: OpenVPN is new and secure, although you will need to install a third-party application. This is the one you should probably use. Layer 2 Tunnel Protocol is a VPN protocol that doesnt offer any encryption. Thats why its usually implemented along with IPsec encryption. As its built into modern desktop operating systems and mobile devices, its fairly easy to implement. But it uses UDP port 500 that means it cant be disguised on another port, like OpenVPN can. Its thus much easier to block and harder to get around firewalls with. IPsec encryption should be secure, theoretically. There are some concerns that the NSA could have weakened the standard, but no one knows for sure. Either way, this is a slower solution than OpenVPN. The traffic must be converted into L2TP form, and then encryption added on top with IPsec. Its a two-step process. In Summary: L2TP/IPsec is theoretically secure, but there are some concerns. Its easy to set up, but has trouble getting around firewalls and isnt as efficient as OpenVPN. Stick with OpenVPN if possible, but definitely use this over PPTP. Secure Socket Tunneling Protocol was introduced in Windows Vista Service Pack 1.

Then, the attacker will be able to decrypt and analyse the traffic carried in the PPTP VPN. PPTP does not provide forward secrecy, so just cracking one PPTP session is sufficient to crack all previous PPTP sessions using the same credentials.
What is PPTP? Webopedia.
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.

You can help by expanding it. The Point-to-Point Tunneling Protocol PPTP is a method for creating virtual private networks. PPTP allows the Point-to-Point Protocol PPP to be tunneled through an IP network on TCP port 1723. PPTP has many security vulnerabilities and is considered obsolete.

PPTP is not as secure as IPsec and cannot secure two networks like IPsec can. PPTP is often replaced by Layer 2 Tunnelling Protocol L2TP which is another VPN protocol that provides security using IPsec, and PPTP has also been made obsolete by L2TP and IPsec.

Use this program to connect to an employer's' PPTP based VPN, or to certain cable and ADSL service providers. By default, pptp establishes the PPTP call to the PPTP server, and then starts an instance of pppd to manage the data transfer.
Using PPTP.
Point-to-Point Tunneling Protocol PPTP is another tool that is used to establish a secure connection between an unsecured remote host and a protected network. It supports up to 50 concurrent sessions for each Firebox and works with any Firebox encryption level.
