Message forwarding method and device

Abstract

The embodiment of the invention provides a message forwarding method and device applied to a BRAS (Broadband Remote Access Server). The method comprises the following steps: receiving a message; whenthe message does not carry VPN (Virtual Private Network) information, searching a first corresponding relationship including a source address and a destination address of the message from a pre-storedcorresponding relationship between the address of the server, the address of a client and the VPN information, wherein the client is equipment that passes the Portal authentication of the server andacquires the VPN information authorized by the server; searching a first route of corresponding equipment that points to the destination address of the message in the VPN information included in the first corresponding relationship from a VPN route, wherein the VPN route comprises a route that points to the client; and transmitting the message to equipment corresponding to the destination addressof the message according to the first route. The embodiment of the invention realizes the communication between the client and the server when the BRAS is used an egress router, and realizes the access mode of Portal.

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...

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.
