Problems solved by technology

[0010] In view of this, the purpose of the present invention is to provide a method and device for accessing the intranet resources of the VPN server, which can solve the problem that the user host cannot work normally due to the overlapping of the intranet segment of the VPN server and the intranet segment of the host side. Problems accessing intranet resources on the VPN server

Embodiment Construction

[0034] Please continue to refer to figure 2, since the intranet where the PC is located and the intranet of the VPN gateway are both in the 192.168.1.0 / 24 network segment, you want to be able to access both the local area network in the environment where the PC is located and the intranet with the same address in the VPN virtual private network One method is to modify the intranet segment of the PC, and change the intranet address of the PC and the router for home or office use to another network segment (such as 192.168.100.0 / 24), so that it no longer overlaps with the VPN intranet address. However, this requires the user to understand some relevant network knowledge, and the interface address of the router also needs to be allowed to be modified. If the user is on a business trip and surfs the Internet in a hotel, the router address cannot be changed at will.

[0035] To this end, the embodiment of the present invention provides a method and device for accessing the intrane...

Abstract

The invention provides a method and device for accessing an intranet resource of a virtual private network (VPN) server. The method includes that a real internet protocol (IP) address is used for building tunnel connection with the VPN server, and a virtual IP address sent by the VPN server and an accessible intranet section resource are obtained; an intranet section of the VPN server is overlapped with an intranet section of a host side, the intranet section of the VPN server is changed into a proxy network section which is not overlapped with the intranet section of the host side, and an output interface of the proxy network section is added into a routing table and used as a virtual IP route; if addresses are overlapped, users are prompted to revise an accessed target IP address into an IP address in the proxy network section; and a datagram reaching a virtual network interface card is obtained, the target IP address is restored into the IP address in the intranet section of the VPN server, and the datagram is packaged into a tunnel datagram and sent out through a tunnel. By means of the method and device, the problem that a user host can not access the intranet resource of the VPN server normally due to address overlapping can be solved.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for accessing intranet resources of a VPN server. Background technique [0002] Secure Sockets Layer (Secure Sockets Layer, SSL) is a set of Internet data security protocols, which have been widely used for identity authentication and encrypted data transmission between web browsers and servers. The SSL protocol is located between the TCP / IP protocol and various application layer protocols. It is built on a reliable transmission protocol (such as the TCP protocol), and provides data encapsulation, compression, encryption and other security support for high-level protocol data communication. [0003] A virtual private network (Virtual Private Network, VPN) is defined as establishing a temporary, secure connection through a public network (usually the Internet), and is a safe and stable tunnel through a chaotic public network. The virtual private network is...
