Internal network resource access method and apparatus based on VPN (Virtual Private Network)

Abstract

The invention discloses an internal network resource access method based on a VPN (Virtual Private Network). The internal network resource access method comprises the steps of when receiving an internal network resource access request forwarded by an access terminal via an access point, replacing a real IP address of the access terminal in the access request into a preset virtual IP address; forwarding an access request using the virtual IP address to an internal network server, and receiving a resource data packet sent by the server in response to the access request; according to the virtual IP address, determining a corresponding access point to return the resource data packet; and forwarding the resource data packet to the corresponding access point, so as to forward the resource data packet to a corresponding access terminal via the corresponding access point. The invention further discloses an internal network resource access device based on the VPN. According to the internal network resource access method and device, the problem that the access point cannot be determined possibly due to a fact that a network segment conflict exists when the internal network resource is forwarded and thus the internal network resource access is failed can be avoided; and the reliability of the internal network resource access is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for accessing intranet resources based on a virtual private network (VPN). Background technique [0002] Such as figure 1 As shown, generally, wireless access points (Wireless Access Points) deployed remotely use the local forwarding mode to forward traffic data, thereby saving bandwidth consumption caused by tunnel closure. However, in such scenarios, after the user terminal accesses the wireless access point network, it cannot access the intranet resources on the side of the wireless controller WAC (Wireless Access Point Controller). Instead, a virtual private network VPN (Virtual Private Network) is used. By establishing a dedicated network on the public network and performing encrypted communication, user terminals can access the intranet resources on the side of the wireless controller through the wireless access point AP. However, the encapsulati...
