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 present invention relates to the field of communication technology, and in particular to a portal (Portal) authentication method, access device, management server and Portal server. Background technique [0002] Portal authentication is a commonly used authentication method for a terminal to access the network. When a terminal accesses the network, it visits any Internet (WEB) page to initiate a Hyper Text Transfer Protocol (HTTP) message, which is accessed by the network. The access device (referred to as the access device for short) redirects the HTTP message to the Portal server. The terminal enters the account password on the authentication page provided by the Portal server for authentication. After passing the authentication, it can access the network normally. Since Portal authentication does not require the installation of authentication client software, and the terminal can be authenticated through a browser, it is widely used. [0003] Portal a...

Problems solved by technology

[0014] However, in more and more Portal authentication scenarios, Network Address Translation (NAT) 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 (WLAN) network (WLAN for short) authentication scenario, WLAN access devices——Access Points (APs) are scattered in various places, and Portal servers and AAA servers are deployed in the data center of the public cloud. APs, Portal servers, and AAA servers There may be a NAT device between them, 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, which may cause the Portal server in the public cloud in the above step 3 Portal authentication request cannot be completed due to Portal authentication request
