Problems solved by technology

[0005] In this case, after the server 102 performs Portal authentication on the client 101 and authorizes the VPN information for the user, the client 101 binds the VPN information, but the server 102 does not bind the VPN information. When the client 101 sends a packet, the BRAS 100 will not be able to find the route pointing to the client 101 in the public network routing, and thus the packet cannot be sent to the client 101
[0006] Based on the above situation, it can be seen that when the BRAS is used as an egress router, the client cannot communicate with the server, and cannot support the Portal access method.

Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0032] like figure 1 In the shown network, BRAS 100 is used as an egress router. The messages sent by client 101 to server 102 and the messages sent by server 102 to client 101 are all via BRAS 100. Portal access mode is deployed on BRAS 100. BRAS 100 and server 102 connection, server 102 is the collection of Web server, Portal server, AAA server; At this moment, the process of Portal authentication is:

[0033] 1. The client 101 sends an online authentication request to the BRAS 1...

Abstract

The embodiment of the present application provides a message forwarding method and device, which are applied to BRAS. The method includes: receiving a message; when the message does not carry VPN information, from the pre-stored server address, client address and VPN information Find the first correspondence between the source address and the destination address of the message in the correspondence, the client is a device that has passed the Portal authentication of the server and obtained the VPN information authorized by the server; find the VPN information included in the first correspondence from the VPN route Pointing to the first route of the device corresponding to the destination address of the message; the VPN route includes a route pointing to the client; according to the first route, the message is sent to the device corresponding to the destination address of the message. By applying the embodiment of the present application, the communication between the client and the server is realized when the BRAS acts as the egress router, and the Portal access mode is realized.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message forwarding method and device. Background technique [0002] Portal (portal) authentication can also be called Web (network) authentication, which accepts the user name and password entered by the user through the Web page, and performs identity authentication on the user, so as to achieve the purpose of access control on user access. [0003] At present, the process of Portal authentication is: the user sends an online authentication request to the BRAS (Broadband Remote Access Server, Broadband Remote Access Server) through the client; BRAS replies to the client with the URL (Uniform Resource Locator, Uniform Resource Locator) of the Web server; The client sends user information such as user name and password to the Web server according to the URL of the Web server; the Web server sends the user information to the Portal server; the Portal server s...
