Embodiment 1

[0055] figure 2 It is a flow chart of an IP acquisition method provided in Embodiment 1 of the present invention, specifically including the following processing steps:

[0056] Step 201, install the bound SSO control and VPN control on the browser of the external network terminal.

[0057] Wherein, the VPN control is equivalent to a VPN client. The bound SSO control and VPN control can be installed by the external network terminal user using the external network terminal.

[0058] Step 202, the external network terminal uses the VPN control to send an access request to the VPN server.

[0059] Wherein, the access request carries an intranet target address to be accessed by the external network terminal.

[0060] Specifically, the external network terminal user uses the VPN control to apply for a VPN account, and uses the applied VPN account to enter the target address of the internal network to be accessed on the browser page, and the external network terminal uses the VP...

Embodiment 2

[0078] Based on the same inventive concept, according to the IP address acquisition method provided in the above-mentioned embodiments of the present invention, correspondingly, Embodiment 1 of the present invention also provides an IP address acquisition device, the structural diagram of which is as follows image 3 shown, including:

[0079] The first obtaining unit 301 is configured to obtain the target address of the internal network to be accessed by the external network terminal when it is detected that the external network terminal uses the VPN control to connect to the VPN server and access the internal network through the VPN server;

[0080] The connection unit 302 is used to establish a connection with the character bastion host connected to the intranet corresponding to the intranet target address;

[0081] The first forwarding unit 303 is configured to forward the source IP address of the external network terminal to the internal network through the character bast...

Abstract

The invention discloses an IP address acquiring method and an IP address acquiring device. The method comprises the following steps: an SSO control acquires an intranet destination address which an extranet terminal is to access when monitoring that the extranet terminal is connected with a VPN server by a VPN control and accesses an intranet through the VPN server; the SSO control establishes connection with a character bastion host which is connected with the intranet corresponding to the intranet destination address; and the source IP address of the extranet terminal is forwarded to the intranet through the character bastion host. By adopting the scheme provided by an embodiment of the invention, the intranet can acquire the source IP address of the extranet terminal when an extranet terminal server accesses the intranet.

Description

technical field [0001] The present invention relates to the communication field, in particular to an IP address acquisition method and device. Background technique [0002] With the advancement of information security technology and the improvement of information security awareness, when users need to access the company's internal office system or mail system and other confidential internal network systems from the wide area external network, the user uses a virtual private network (VPN, Virtual Private Network) The access method of access uses a VPN proxy to access the intranet system, which avoids direct access and malicious attacks by external network users to the internal system of the enterprise. [0003] At present, the existing ways of accessing the intranet system in the existing virtual private network are as follows: an external network user downloads and installs a VPN control in a local browser, and after the user applies for a VPN account, uses the VPN control t...
