• Web Authentication Type: Choose one of the following methods for web
authentication. The security appliance can authenticate the wireless users
by using the local database and external AAA server (such as RADIUS, AD,
LDAP, and so forth). The authentication method is derived from the user login
settings that you specified in the Users -> Settings page.
- Internal: Uses the default web authentication login page to authenticate
the wireless users. If you choose this option, you can modify the following
information on the default web authentication login page:
Cisco Logo: If you want to hide the Cisco logo that appears in the top
right corner of the default page, choose Hide. Otherwise, choose Show.
Headline: If you want to create your own headline on the login page,
enter the desired text in this field.
Message: If you want to create your own message on the login page,
enter the desired text in this field.
- Internal, No auth with accept button: Allows users to access the
wireless network without entering a user name and password. If you
choose this option, a web passthrough window is prompted. Click the
Accept button to access the network without the user name and
password.
- External Web Server: Uses a customized web authentication login page
on an external web server to authenticate the wireless users. If you
choose this option, enter the IP address of the external web server in the
Authentication Web Server field and the key in the Authentiation Web
Key field. The authentication web key is used to protect the user name
and password that the external web server sends to your security
appliance for authentication.
- External, No auth with accept button: Allows users to access the
wireless network without entering a user name and password. If you
choose this option, a web passthrough window is prompted. Click the
Accept button to access the network without the user name and
password.
• Redirected URL After Login: If you want the wireless users to be directed
to a particular URL (such as the URL for your company) after login, enter the
desired URL (such as www.AcompanyBC.com) in this field. If you do not
specify the portal (keep it blank), the wireless user can access the original
web site directly.
