Enabling wireless LANs (WLANs)

• User authentication - Authenticates users using a Radius server.
• Walled garden support - Enables a list of IP address (not domain names) accessed without
authentication.
• Billing system integration - Sends accounting records to a Radius accounting server.
CAUTION
When using the access point’s hotspot functionality, ensure Clients are re-authenticated when
changes are made to the characteristics of a hotspot enabled WLAN, as Clients within the WLAN
will be dropped from access point device association.
To configure hotspot functionality for an access point WLAN:
1. Ensure the Enable Hotspot check box is selected from within the target WLAN screen, and
ensure the WLAN is properly configured.
Any of the sixteen WLANs on the access point can be configured as a hotspot. For hotspot
enabled WLANs, DHCP, DNS,HTTP and HTTP-S traffic is allowed (before you login to the
hotspot), while TCP/IP packets are redirected to the port on the subnet to which the WLAN is
mapped. For WLANs not hotspot-enabled, all packets are allowed.
2. Click the Configure Hotspot button within the WLAN screen to display the Hotspot
Configuration screen for that target WLAN.
3. Refer to the HTTP Redirection field to specify how the Login, Welcome, and Fail pages are
maintained for this specific WLAN. The pages can be hosted locally or remotely .
.
4. Use the External URL field to specify the location of the login page, welcome page and fail page
used for hotspot access. Defining these settings is required when the Use External URL check
box has been selected within the HTTP Redirection field
.
NOTE
If an external URL is used, the external Web pages are required to forward user credentials to
the access point, which in turn forwards them to the authentication Server (either onboard or
external server) in order to grant users Web access.
Use Default Files Select the Use Default Files checkbox if the login, welcome and fail pages
reside on the access point.
Use External URL Select the Use External URL checkbox to define a set of external URLs for
hotspot users to access the login, welcome and fail pages. To create a
redirected page, you need to have a TCP termination locally. On receiving the
user credentials from the login page, the access point connects to a radius
server, determines the identity of the connected wireless user and allows
the user to access the Internet based on successful authentication.
Login Page URL Define the complete URL for the location of the Login page. The Login
screen will prompt the hotspot user for a username and password to
access the Welcome page.
