Problems solved by technology
[0004] When Portal authentication is combined with the wireless forwarding policy, if the configured node is different from the wired forwarding node determined by the wireless forwarding policy, for example, the configured node is an AP and the wired forwarding node is an AC, or the configured node is an AC and The forwarding node is the AP, which will result in the inability to perform Portal authentication on the STA, that is, directly forward the data packets sent by the STA through wired connections, which will bring great security risks to the network.

Embodiment Construction
[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present 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.
[0024] Currently, when Portal authentication is combined with wireless forwarding policies, if the configuration node for Portal authentication is different from the node for wired forwarding determined by the wireless forwarding policy, it will bring great security risks to the network.
[0025] Such as figure 1 The networking shown includes ACs, APs, and STAs. If configuration nodes and Portal authentication information are set on the AC, the AC ...

Embodiments of the present application provide a Portal authentication method and device, which are applied to APs. The method includes: receiving a Portal authentication message sent by an STA; judging whether a mandatory policy is stored, and the mandatory policy is used to instruct the AP to perform Portal authentication on the STA; If so, perform Portal authentication on the STA according to the Portal authentication message and the locally stored Portal filtering rules. Applying the technical solution provided by the embodiment of the present application improves network security under the combination of Portal authentication and wireless forwarding strategy.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to a portal (Portal) authentication method and device. Background technique [0002] Currently, in a WLAN (Wireless Local Area Network, wireless local area network), packet forwarding modes include centralized forwarding and local forwarding. Wherein, the centralized forwarding means that the message of the station (STA, Station) is forwarded to the access controller (AC, Access Controller) through the access point (AP, Access Point), and the AC performs wired forwarding. Local forwarding means that the STA's packets are forwarded by the AP through the wire. To meet the requirements of different users for the forwarding mode, the AP can forward user packets according to the wireless forwarding policy. Among them, the wireless forwarding policy includes two parts: forwarding rules and forwarding behaviors. The wireless forwarding policy includes one or more fo...
