Abstract: A virtual private network implementation method includes intercepting, by an NDIS intermediate driver, a packet sent by an application program to an intranet server, and determining, according to a PID corresponding to the packet, whether to allow a process corresponding to the packet to use an SSL VPN; when the process corresponding to the packet is allowed to use the SSL VPN, establishing, by the NDIS intermediate driver, a new packet, and submitting the new packet to an NDIS network interface card driver; and sending, by the NDIS network interface card driver, the new packet to the client, and sending, by the client, the new packet to the intranet server. Thereby, a virtual private network is implemented based on process control, and a client has a fast startup speed.
