PPTP Server
The Point-to-Point Tunneling Protocol (PPTP) is a Layer2 tunneling protocol for implementing
virtual private networks through IP network.
In the Microsoft implementation, the tunneled PPP traffic can be authenticated with PAP, CHAP, and
Microsoft CHAP V1/V2 . The PPP payload is encrypted using Microsoft Point-to-Point Encryption
(MPPE) when using MSCHAPv1/v2.
Note: 8 sessions for Server and 8 sessions for Client respectively.
PPTP Server: Select Actived to activate PPTP Server. Deactived to deactivate PPTP Server.
Authentication Type: The authentication type, Chap/Pap, Pap, Chap or MS-CHAPv2 Encryption.
When using PAP, the password is sent unencrypted, whilst CHAP encrypts the password before
sending, and also allows for challenges at different periods to ensure that an intruder has not replaced
the client. When passed the authentication with MS-CHAPv2, the MPPE encryption is supported.
