With the PPTP VPN server it can be for surf secure in a public hotspot, tunnels your VoIP Connection, encrypted Internet connection, allows anonymous internet surfing, watch & stream Live TV abroad, can't track your real IP Address.
PPTP (Point-to-Point Tunneling Protocol) is an outdated method for implementing virtual private network (VPN). PPTP uses TCP control channels and GRE tunnels to encapsulate PPP packages.PPTP has been the subject of security analysis and serious security vulnerabilities have been found in the protocol.
PPTP is a tunnel that is safe for transporting IP traffic using PPP. PPP encapsulates PPP in virtual paths that run above IP. The purpose of this protocol is to make a secure connection that is managed well between routers and also between routers and PPTP clients. PPTP combines PPP and MPEE (Microsoft Point to Point Encryption) to create an encrypted link.
The main facility of using PPTP is being able to use a public-switched telephone network (PSTN) to build a VPN. The development of easy and low-cost PPTP to be used widely is a solution for remote users and mobile users, because PPTP provides security and encryption of communication through PSTN or the internet.
Authentication of network users is done using an authentication protocol that is in the Windows NT Remote Access Service (RAS) - PAP and CHAP. MS-CHAP supports MD4 hashes and DES used in LAN Manager. Additional authentication can be done by the ISP at the end of the relationship between the user and the ISP if needed. Data encryption is done using the RAS-RSA RC4 encryption protocol. By using Microsoft Remote Access Services (RAS), we can reduce compression, encryption and integration time into the Windows NT administration model. PPTP also uses security facilities provided by PPP, MS-CHAP (PPP authentication) and is used to validate user data in domains on Windows NT. The result is a session key that is used to encrypt user data. In addition, Microsoft implements CCP (Compression Control Protocol) which has bits for encryption negotiation.
