Embodiment 1

[0036] see figure 1 , which is a flowchart of a method for assigning a fixed virtual network address provided in Embodiment 1 of the present invention, the method for assigning a fixed virtual network address includes:

[0037] S101: The gateway receives a packet carrying a virtual IP address request sent by a terminal (such as a client).

[0038] S102: The gateway obtains the user identity of the terminal. Mainly through the following methods: the gateway acquires the user identity of the terminal according to the user information carried in the message received in S101; or, acquires the user identity of the terminal according to the information (username and password) input by the terminal; or, acquires the user identity of the terminal according to the certificate of the current terminal Get the user identity of the terminal.

[0039] S103: Query the virtual network (IP, Internet Protocol) address bound to the user identity on the authentication server according to the us...

Embodiment 2

[0045] see figure 2 , which is a flowchart of a method for assigning a fixed virtual network address provided by Embodiment 2 of the present invention, the method for assigning a fixed virtual network address includes:

[0046] S201: The administrator or user sets a legal user virtual IP address for the user identity (such as user account record) on the authentication source or authentication server, and binds the set user virtual IP address with the user identity, and the user passes through the authentication at the remote end. After the client software logs in to the gateway and starts the network service, it sends a request packet carrying a virtual IP address to the gateway.

[0047] S202: The gateway obtains the user identity mainly through the following methods: the gateway obtains the user identity of the terminal according to the user information carried in the packet carrying the virtual IP address request; or obtains the user identity according to the information inp...

Embodiment 3

[0056] see image 3 , which is a flowchart of a method for assigning a fixed virtual network address provided in Embodiment 3 of the present invention, the method for assigning a fixed virtual network address includes:

[0057] S301: The user logs in to the gateway through a browser at the remote end, and after enabling the network extension service, the user sends a message carrying a virtual IP address request to the gateway through the browser.

[0058] S302: The gateway obtains the user identity (such as the user name) through information input by the user on the webpage (such as user name and password), or through the certificate displayed by the user on the webpage.

[0059] S303: The gateway sends a request for finding a virtual IP address bound to the user identity to the authentication source or the authentication server according to the user identity obtained in S302.

[0060] S304: The authentication source or the authentication server searches for the virtual IP a...

Abstract

The embodiment of the invention belongs to the technical field of communication and provides a method for distributing a fixed virtual network address. The method comprises: receiving a message carrying a virtual network address request sent by a terminal; obtaining user identity of the terminal and according to the user identity, inquiring a virtual network address; according to an inquired result, distributing the fixed virtual network address for the terminal; and returning a response message carrying the fixed virtual network address to the terminal. The embodiment of the invention also provides a gateway. The embodiment can meet that a user can obtain the fixed virtual IP address at any moment and any place under the condition of higher requirement of mobility, and is convenient for user management, on-line control and user action audit.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method for allocating fixed virtual network addresses and a gateway. Background technique [0002] The openness and commercialization of the Internet have enabled the rapid development of the Internet, but the openness of the Internet has also brought about network security issues. With the increasing popularity of Internet applications, hackers and viruses are pervasive, which has caused unprecedented threats to network information systems. [0003] As the main body of informatization, enterprises are the most common practitioners of information technology. In the process of informatization, on the one hand, enterprises need to expand the access areas of their intranet application service resources and data resources to meet more and more remote access requirements, such as branch office access, partner access, customer access, etc. access, employee access on business ...
