A portal authentication method, access device and management server

Abstract

The invention discloses a Portal authentication method, an access device, a management server, and a Portal server. An access device sends a result query request to a management server and receives a first corresponding relation returned by the management server in response to the result query request, wherein the first corresponding relation comprises first authentication ID and a first authorization result, and the first corresponding relation is provided by a Portal server for the management server; and the access device, according to authentication indication in the first authorization result and the first authentication ID, determines whether a first terminal succeeds in Portal authentication, and according to authorization information in the first authorization result, determines whether to forward a hyper text transfer protocol (HTTP) message of the first terminal such that Portal authentication can be completed under the condition that an NAT device exists between the first terminal and the Portal server.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a portal (Portal) authentication method, access equipment, a management server and a Portal server. Background technique [0002] Portal authentication is a commonly used authentication method for terminal access to the network. When the terminal accesses the network, it visits any Internet (WEB) page to initiate a Hyper Text Transfer Protocol (HTTP) message, which is sent by the network The access device (abbreviated as the access device) redirects the HTTP message to the Portal server, and the terminal enters the account password on the authentication page provided by the Portal server for authentication, and can normally access the network after passing the authentication. Because Portal authentication does not require the installation of authentication client software, terminals can be authenticated through browsers, so it is widely used.

Problems solved by technology

[0014] However, in more and more Portal authentication scenarios, Network Address Translation (NAT for short) is required between the access device and the Portal server, and between the access device and the AAA server, such as wireless local area network (wireless local area network). area network (WLAN for short) authentication scenario, the access point (Access Point, AP) of the WLAN access device is scattered in various places, the Portal server and the AAA server are deployed in the data center of the public cloud, and the AP and the Portal server, AAA There may be a NAT device between the servers, so that sometimes the packets sent by the Portal server and the AAA server to the access device cannot be received by the access device. The device sends a Portal authentication request, so Portal authentication cannot be completed
