--> Web Authentication is a method where wireless users use a Web interface to enter credentials before being allowed to access the network.
--> Wireless User detects the SSID, sends an Authentication request and receives an authentication success reply.
--> Layer 2 Authentication can be configured or may be optional in case of web authentication.
--> Wireless User sends an association request and receives the association reply from Access Point where it is connected.
--> At this moment, the client is associated with Access Point can only send two types of traffic: DHCP and DNS.
--> In case, If you configured a pre-authentication ACL in Wireless LAN Controller, make sure that your Pre Auth ACL does allow DNS and DHCP traffic.
--> So that the Wireless User can get an IP address and DNS server information from DHCP Server in the network.
--> Once Wireless User gets an IP address and DNS server information, now the user tries to browse some websites by opening web browser.
--> Once the wireless controller receives the DNS answer from DNS Server for the wireless user request, the controller redirects the browser to the Web authentication page.
--> There are several common issues that you may face, if the Web Authentication is not configured Properly.
