Embodiment 1

[0044] figure 1 A schematic structural diagram of a multi-protocol VPN gateway fusion system of the present invention is shown. Please refer to figure 1 , the multi-protocol VPN gateway fusion system of the present invention includes a fusion server 101, a first VPN device 102 and a second VPN device 103;

[0045] The first VPN device and the second VPN device are connected in communication with the fusion server 101 respectively; the first VPN device 102 and the second VPN103 equipment are used for receiving / sending VPN ciphertext data packets, and the fusion server 101 is used for connecting the first VPN device 102 and the first VPN device 102 and VPN protocol conversion and / or forwarding of VPN ciphertext data packets transmitted between the second VPN devices 103;

[0046] The fusion server 101 includes more than one Docker container, an external VPN protocol gateway, a physical network card, a system kernel, a first virtual network card and a second virtual network car...

Embodiment 2

[0055] figure 2 A flow chart of a multi-protocol VPN gateway fusion method of the present invention is shown. Please refer to figure 2 , a multi-protocol VPN gateway fusion method, comprising the following steps:

[0056] S101: The first VPN device sends a VPN ciphertext data packet;

[0057] S102: The VPN ciphertext data packet arrives at the physical network card of the fusion server;

[0058] S103: The external VPN protocol gateway reads the VPN ciphertext data packet from the physical network card through the user state network card driver and judges whether the VPN protocol adopted by the VPN ciphertext data packet is the same as the VPN protocol adopted by itself, if not, proceed to step S104; if same, proceed to step S105;

[0059] S104: The VPN ciphertext data packet is first decrypted by the internal VPN protocol gateway using the same VPN protocol as the VPN ciphertext data packet, and then the plaintext data packet is encrypted by the external VPN gateway acco...

Abstract

The invention belongs to the technical field of network security, and relates to a multi-protocol VPN gateway fusion system and method. The multi-protocol VPN gateway fusion system comprises a fusion server, a first VPN device and a second VPN device, wherein the first VPN equipment and the second VPN equipment are used for receiving / transmitting VPN ciphertext data packets, and the fusion server is used for performing VPN protocol conversion and / or forwarding on the VPN ciphertext data packets transmitted between the first VPN equipment and the second VPN equipment; the fusion server comprises more than one Docker container, an external VPN protocol gateway, a physical network card, a system kernel, a first virtual network card and a second virtual network card; one inner VPN protocol gateway is correspondingly arranged in each Docker container, and the outer VPN protocol gateway is arranged outside the Docker container. According to the invention, two or more VPN protocol gateways are quickly fused through the Docker container, hardware resources are saved, so that convenience and rapidness are achieved, and the serial communication requirements of various VPN protocols can be quickly met.

Description

technical field [0001] The invention belongs to the technical field of network security, and relates to a multi-protocol VPN gateway fusion system and method. Background technique [0002] VPN is a virtual private network, which can establish a private network on a public network for encrypted communication, and is widely used in enterprise networks. The VPN gateway realizes remote access by encrypting the data packet and converting the destination address of the data packet. [0003] In the existing gateways that support multiple VPN protocols, each VPN protocol is isolated from each other, and it is impossible to implement multi-VPN protocol serial encryption for a single service, and most of them can only select one VPN access method at the same time. In order to meet the requirement of cascading and encrypting multiple VPN protocols for a single service, the traditional implementation method is to deploy multiple VPN devices, which leads to complex networking and waste ...
