What Is PPTP: Point-to-Point Tunneling Protocol.
Voluntary Tunneling: A type of tunneling that is initiated by the client on an existing connection with a server. Compulsory Tunneling: A type of tunneling initiated by the PPTP server at the ISP, which requires the remote access server to create the tunnel. Is PPTP Still Being Used?

Point-to-Point Tunneling Protocol Wikipedia.
MS-CHAP-v2 is vulnerable to dictionary attacks on the captured challenge response packets. Tools exist to perform this process rapidly. In 2012, it was demonstrated that the complexity of a brute-force attack on a MS-CHAP-v2 key is equivalent to a brute-force attack on a single DES key. An online service was also demonstrated which is capable of decrypting a MS-CHAP-v2 MD4 passphrase in 23 hours. MPPE uses the RC4 stream cipher for encryption. There is no method for authentication of the ciphertext stream and therefore the ciphertext is vulnerable to a bit-flipping attack. An attacker could modify the stream in transit and adjust single bits to change the output stream without possibility of detection. These bit flips may be detected by the protocols themselves through checksums or other means. EAP-TLS is seen as the superior authentication choice for PPTP; 11 however, it requires implementation of a public-key infrastructure for both client and server certificates.
