What is PPTP function on Reyee gateway?

Overview
Point-to-Point Tunneling Protocol (PPTP) is an enhanced security protocol designed based on the Point-to-Point Protocol (PPP). It allows an enterprise to use private tunnels to expand its enterprise network over the public network. PPTP relies on the PPP protocol to implement security functions such as encryption and identity authentication. Generally, PPTP works with Password Authentication Protocol (PAP), Challenge Handshake Authentication Protocol (CHAP), Microsoft Challenge Handshake Authentication Protocol(MS-CHAPv1/v2), or Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) for identity authentication and Microsoft Point-to-Point Encryption(MPPE) for encryption to improve security.
Currently, the device can be deployed as the PPTP server or client. It supports MPPE for encryption MSCHAPv2 for identity authentication, and does not support EAP authentication.
Configuringthe PPTP Service
1. Configuring the PPTP Server
Choose One-Device > Gateway > Config > VPN> PPTP > PPTP Settings
Turn on the PPTP function, set PPTP Type to Server,configure PPTP server parameters, and click Save.



Caution
The local tunnel address and IP address range ofthe address pool cannot overlap the network segment of the LAN port on the device.
2. Configuring PPTP User
Choose One-Device > Gateway > Config > VPN> VPN Account.
Only user accounts added to the VPN client list are allowed to dial up to connect to the PPTP server. Therefore, you need to manually configure user accounts for clients to access the PPTP serveram
Click Add. In the dialog box that appears, setService Type to PPTP or ALL. (If you select ALL, the created account can beused to establish all types of VPN tunnels.) Enter the username, password, andpeer subnet, select a network mode, and click OK.


Configuring the PPTP Client
Choose One-Device > Gateway > Config > VPN> PPTP > PPTP Settings
Turn on the PPTP function, set PPTP Type to Client,configure PPTP client parameters, and click Save.



Viewing the PPTP Tunnel Information
Choose One-Device > Gateway > Config > VPN> PPTP > Tunnel List.
It takes some time to establish a VPN connection between the server and client. After the configuration of the server and client is completed, wait for 1 to 2 minutes to refresh the page and view the PPTP tunnel establishment status
