Web Authentication for Mobile Users
Overview
The Web-Auth Process
To provide limited network access to mobile users through Web-Auth, you set up a
Dynamic Host Configuration Protocol (DHCP) server and instruct the users to
configure their stations to receive a dynamic IP address from this server. (This DHCP
server can be an external server or the Wireless Edge Services zl Module’s internal
server.) When a mobile user tries to associate with a wireless LAN (WLAN) that is
configured for Web-Auth, the user’s station requests an IP address from the DHCP
server. (See Figure 5-1.)
