Wireless network validating identity firewalled

Chapter 9 802.1x Authentication 802.1x is an Institute of Electrical and Electronics Engineers (IEEE) standard that provides an authentication framework for WLANs.802.1x uses the Extensible Authentication Protocol (EAP) to exchange messages during the authentication process.

The gateway APs (authenticator) role is to send authentication messages between the supplicant and authentication server.By default, 802.1X authentication on Window 8.1/10 consists of not only client authentication, but also server authentication, which requires the server (here is the Vigor AP) to provide certificate information to the client.However, if the model or the firmware version does not support Certificate Configuration yet, we may set up the Windows client not to verify the server's identity, and still do 802.1X authentication with Vigor Router or Vigor AP.Gateway APs need to receive a RADIUS Access-accept message from the RADIUS server in order to grant the supplicant access to the network.For best performance, it is recommended to have the RADIUS server and gateway APs located within the same layer-2 broadcast domain to avoid firewall, routing, or authentication delays.This chapter describes the following topics: The authentication server provides a database of information required for authentication and informs the authenticator to deny or permit access to the supplicant.The 802.1x authentication server is typically an EAP-compliant Remote Access Dial-In User Service (RADIUS) server which can authenticate either users (through passwords or certificates) or the client computer.Many laptop computers have wireless cards pre-installed.The ability to enter a network while mobile has great benefits.An example of an 802.1x authentication server is the Internet Authentication Service (IAS) in Windows (see).Arubauser-centric networks, you can terminate the 802.1x authentication on the controller .
