Description

Technical Field

[0001] The present invention relates to a VPN (Virtual Private Network) multi-channel local area networking system and method based on Docker containerization technology. Background Art

[0002] With the rapid development of information technology, the demand for network connections between enterprises and organizations is increasing. In the traditional network environment, physical dedicated lines or VPNs are used to achieve remote office and remote device interconnection, but these methods usually require complex network configuration and expensive hardware equipment, making network deployment and management cumbersome and expensive.

[0003] With the rise of container technology, Docker has become a popular containerization technology, which allows applications and services to run in independent containers, achieving application isolation and portability. The emergence of Docker has brought revolutionary changes to the deployment and management of network services. At the same time, VPN technology, as an important means to ensure network communication security, is also constantly evolving and improving to meet the growing network security needs.

[0004] However, there are still some challenges in implementing multiple LAN networks on a single server. Traditional VPN networks require complex configuration and management, and existing container technologies often fail to integrate VPN technology well, thus limiting the implementation of multi-channel LAN networking in a container environment. Summary of the invention

[0005] To overcome the above-mentioned defects, the object of the present invention is to provide a VPN multi-channel local area networking system and method based on Docker.

[0006] To achieve the above object, the VPN multi-channel local area networking method based on Docker of the present invention at least comprises the following steps:

[0007] Create a WireGuard server container using Docker;

[0008] Inside the WireGuard server container, configure the VPN server side;

[0009] On each device that needs to connect to the VPN, create a WireGuard client container using Docker.

[0010] Configure the WireGuard client inside each WireGuard client container.

[0011] Furthermore, the method also includes the steps of installing Docker on the server and configuring the Docker operating environment.

[0012] Furthermore, it also includes the steps of configuring the WireGuard server inside the WireGuard server container, generating the public key and private key of the WireGuard server, and mapping the server port to a port on the server.

[0013] Furthermore, the steps of configuring the WireGuard client are specifically as follows: inside each client container, add the public key of the VPN server to the client's configuration file and set the client's virtual LAN IP address; configure the client's firewall rules to ensure that VPN traffic is allowed to pass.

[0014] Furthermore, it also includes the steps of starting the connection; starting the WireGuard connection on all containers; and ensuring that the VPN connection is successfully established and that the client devices can communicate with each other.

[0015] Furthermore, the step of configuring routing is also included; configuring routing on each client container to ensure that traffic can be correctly forwarded to the target LAN through the WireGuard tunnel.

[0016] To achieve the above object, the present invention provides a system for VPN multi-channel local area networking based on Docker, comprising:

[0017] WireGuard server container, created using Docker;

[0018] A VPN server is configured inside the WireGuard server container;

[0019] A WireGuard client container, created using Docker on each device that needs to connect to the VPN;

[0020] A WireGuard client is configured in each WireGuard client container;

[0021] Each device establishes an encrypted tunnel and transmits network data connection through the WireGuard client and VPN server using the WireGuard protocol.

[0022] The present invention uses the WireGuard protocol as the core of VPN technology, combined with Docker container technology, to create multiple virtual LANs on a server, so that different devices can be securely interconnected through VPN to achieve multi-way LAN networking. This system provides a simple, efficient and secure network connection, which is suitable for scenarios such as enterprise intranet topology expansion and remote device interconnection.

[0029] A WireGuard client container, created using Docker on each device that needs to connect to the VPN;

[0030] A WireGuard client is configured in each WireGuard client container;
