Embodiment 1

[0021] Such as figure 1 As shown, this embodiment provides a VPN access method, including:

[0022] Step 101, the user terminal sends a VPN access request to the unified portal server.

[0023] In this embodiment, the unified entry server in step 101 can uniformly receive VPN access requests sent by all user terminals, that is, all user terminals send VPN access requests to the unified entry server when they need to access the VPN. The VPN access request carries the VPN gateway type to be accessed, and the gateway type includes a Secure Socket Layer Virtual Private Network (Security Socket Layer Virtual Private Network, SSL VPN) or an Internet Protocol Security Virtual Private Network (Internet Protocol Security Virtual Private Network). Network, IPSec VPN).

[0024] In this embodiment, the user terminal needs to access each type of VPN, and different clients may be used for each type of VPN, which is not limited here.

[0025] Step 102, the unified portal server receives t...

Embodiment 2

[0035] Such as figure 2 As shown, this embodiment provides a VPN access method, including:

[0036] Step 201, the user terminal sends a VPN access request to the unified portal server. The process is related to figure 1 The shown step 101 is similar and will not be repeated here.

[0037] In step 202, the unified portal server monitors whether a VPN access request is received.

[0038] In this embodiment, when the monitoring result of step 202 is yes, step 203 is performed; otherwise, step 202 is repeatedly performed.

[0039] Step 203, the unified portal server determines the VPN type according to the VPN access request.

[0040] From step 204 to step 206, the unified portal server selects a target VPN gateway according to the VPN type, and sends a VPN access request to it, and the target VPN gateway establishes a communication logical channel with the user terminal according to the request. The above process and figure 1 Steps 103 to 105 shown are similar and will not...

Embodiment 3

[0049] Such as Figure 5 As shown, the embodiment of the present invention provides a VPN access method, which is the same as figure 1 Similar to shown, except that, for identity verification purposes, also include:

[0050] Step 106, the user terminal receives the authentication information input by the user, and sends the authentication information to the target VPN gateway through the logical communication channel.

[0051] Step 107, the target VPN gateway receives the authentication information sent by the user terminal, and performs identity authentication according to the authentication information.

[0052] The present invention has the following beneficial effects: the unified entrance server receives the VPN access request sent by the user terminal, and after determining the VPN type, sends the VPN access request to the corresponding target VPN gateway, so that the target VPN gateway establishes communication logic with the user terminal channel to realize VPN acces...

Abstract

The invention discloses a VPN accessing method and relates to the field of network security. The problems that in the prior art, for different kinds of VPN gateways, different accessing interfaces are deployed, the hardware demanding quantity is large, and managing efficiency is low are solved. The method comprises the steps that S10. a user terminal sends a VPN accessing request to a unified interface server, the unified interface server can receive VPN accessing requests sent by all user terminals in a unified mode, and the VPN accessing requests carry the types of VPN gateways to be subjected to accessing; S20. the unified interface server receives the VPN accessing requests sent by the user terminals, and the VPN types are determined according to the VPN accessing requests; S30. according to the VPN types, the unified interface server selects a target gateway cluster from a preset VPN gateway cluster; S40. the unified interface server selects a target VPN gateway from the target gateway cluster, and the VPN accessing requests are sent to the target VPN gateway; and S50. the target VPN gateway receives the VPN accessing requests sent by the unified interface server, and a communication logic channel with the user terminals is established according to the VPN accessing requests.

Description

technical field [0001] The invention relates to the field of network security, in particular to a VPN access method. Background technique [0002] The function of a virtual private network (Virtual Private Network, VPN) is to establish a private network on a public network to realize encrypted communication. In order to meet the requirements of diversified access terminals and high security of the system, it is necessary to deploy multiple VPN gateways. In the prior art, in order to deploy multiple VPN gateways, different access portals need to be deployed for different types of VPN gateways; when a user needs to access a VPN gateway, a request needs to be sent to a corresponding load balancing server. [0003] However, due to the deployment of different access portals for different types of VPN gateways, multiple load balancing servers need to be deployed, resulting in large hardware requirements and low management efficiency. Contents of the invention [0004] The inve...
