Web Authentication for Mobile Users
Overview
Overview
With the ProCurve Wireless Edge Services xl Module, you can require mobile
users to authenticate by entering their login credentials on a Web page. Like
other authentication methods, Web authentication (Web-Auth) is verified
through a Remote Access Dial In User Service (RADIUS) server.
You can use Web-Auth to provide limited network services for mobile users
who visit your company’s office. For example, you might want to provide
Internet access so that these users can browse the World Wide Web or
establish a virtual private network (VPN) to their company’s network.
Through the security provided over a VPN, users can access the applications
(such as email) and the data that they need to do their jobs.
In addition to using Web-Auth to provide network services for visitors, you
can use Web-Auth to provide authenticated access for employees who are
using stations that do not support 802.1X. Because Web-Auth is easy to
configure and provides an easy access method for users, you may also want
to use this authentication method for employees who need limited network
services.
Note
With Web-Auth, mobile users roam seamlessly between RPs adopted by the
same Wireless Edges Services xl Module. To have stations roam at Layer 2
between RPs adopted by different modules, you must place the modules in a
redundancy group. (See
Chapter 10: Redundancy Groups
.) To have stations
roam between modules at Layer 3, you must place the modules in a Layer 3
mobility domain. (See
Chapter 9: Fast Layer 2 Roaming and Layer 3
Mobility
.)
However, the redundancy group, like the module, is limited to adopting 48
RPs. Consider having a single module adopt all RPs. (You can install RPs in
a different subnetwork than the Wireless Edge Services xl Module that adopts
them. See “Network Requirements for Layer 3 Adoption” on page 2-61 of
Chapter 2: Configuring the ProCurve Wireless Edge Services xl Module
.)
