CHAPTER 9

Authentication

This chapter shows you how to set up subscriber authentication on the VSG.

9.1 Authentication Overview

You can set the VSG to authenticate subscriber in a number of ways:

• User agreement

• CAS (Central Authentication Service)

• Built-in authentication

• Remote RADIUS server

By default, subscriber authentication is disabled. This allows all subscribers to access the

Internet without entering account username and password.

9.1.1 User Agreement

In cases where authentication is not required and anyone can access the Internet through the

VSG, you can set the VSG to redirect client users to an Internet service usage agreement page.

Users must accept the service usage agreement before they can access the Internet.

9.1.2 CAS (Central Authentication Service)

The Hilton Group Corporation developed the High Speed Internet Access (HSIA) service to

provide Internet access service across its entire Hilton Group hotels.

In order to use the HSIA, hotel guest(s) must be authenticated through the proprietary CAS (in

the local hotel network or the remote network). The CAS performs both user authentication

and accounting.

Figure 30 CAS Example

The following summarizes the communication steps before Internet access is allowed.
