Pptp Server - Billion BiPAC 4500NZ(L) User Manual

PPTP Server

The Point-to-Point Tunneling Protocol (PPTP) is a Layer2 tunneling protocol for implementing
virtual private networks through IP network. PPTP uses an enhanced GRE (Generic Routing
Encapsulation) mechanism to provide a flow- and congestion-controlled encapsulated datagram
service for carrying PPP packets.
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.
4 sessions for Client and 4 sessions for Server respectively.
Note:
In PPTP session, users can set the basaic parameters(authentication, encyption, peer address, etc) for PPTP
Server and then set the accounts, and 4 accounts or connections are to be set for PPTP Server.
Enable: Select Yes to activate PPTP Server. No to deactivate PPTP Server.
WAN Interface: Select the exact WAN interface configured for the tunnel. Select Default to use the
now-working WAN interface for the tunnel.
Auth. Type: The authentication type, Pap or Chap, and MPPE 128bit 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.
MS-DNS: Directly set the IP of DNS server or let the 192.168.1.254(the router by default) be the
MS-DNS server.
User select: 4 sessions for server by default, user1 stands for the first session, and so does user2,
etc.
Connection Name: User-defined name for the PPTP connection.
Active: Select Enable to activate the account. PPTP server is waiting for the client to connect to this
account.
