Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] see figure 1 , a kind of solution that prevents vpn client address from conflicting with local address, comprises the following steps:

[0024] 1) The client initiates a VPN connection request to the server.

[0025] 2) The server issues a server virtual IP from the virtual address pool, for example, the server virtual IP is (10.1.0.X).

[0026] 3) After the client receives the virtual IP of the server, the client will generate a virtual IP of the cli...

Abstract

The invention discloses a solution for preventing the conflict between the VPN client address and the local address, which comprises the following steps: 1) The client initiates a VPN connection request to the server. 2) The server issues a server virtual IP from the virtual address pool. 3) When the client receives the server virtual IP, the client will generate a client virtual IP, which is directly generated by the client, and the client virtual IP ensures that there is no conflict with the client's local IP. Establish a NAT mapping relationship between the client virtual IP and the server virtual IP issued by the server. 4) The client completes the VPN connection with the server. This method solves the conflict between the virtual IP of the server obtained by the client and the local IP of the client, and does not need to configure multiple network segment virtual address pools on the server, thereby reducing the interaction between the client and the server.

Description

technical field [0001] The invention relates to a solution for preventing the conflict between the VPN client address and the local address. Background technique [0002] A virtual private network (Virtual Private Network, referred to as VPN) refers to the technology of establishing a private network on a public network. The reason why it is called a virtual network is mainly because the connection between any two nodes of the entire VPN network does not have the end-to-end physical link required by the traditional private network, but is structured on the network provided by the public network service provider. Logical network on the platform, user data is transmitted in the logical link. VPN mainly uses tunnel technology, encryption and decryption technology, key management technology and user and device identity authentication technology. VPN is essentially to use encryption technology to encapsulate a data communication tunnel on the public network. [0003] When the ...
