    Abstract: The present disclosure provides a method, apparatus, and device for PPTP VPN based access acceleration. A PPTP VPN system includes a client-side, a first server, a VPN server, and a second server cluster supporting a GRE protocol connected between the first server and the VPN server. When the client-side starts an accelerated access, the first server receives a first PPTP message and a first GRE message from a same client-side, and encapsulates the first GRE message. An encapsulated first GRE message and the first PPTP message are send to a same second server. The first GRE message is encapsulated and the source addresses of the first GRE message and the first PPTP message are changed. Therefore, the reliability of the transmission can be achieved. Reverse transmission is no difference. The present disclosure accelerates the access speed of the VPN server and improves the access quality of the user.
