How it Works Gina dials in to RAS 1500 using PPP (Dial-Up Networking) with the
username and phone number supplied by the administrator. After Gina is
authenticated, the call is disconnected and RAS 1500 dials Gina back at
the phone or alternate phone number. Once reconnected, RAS 1500
attaches the user to the host or gateway specified in the Windows 95
Network dialog box from the Control Panel under Settings. If Gina
exceeds the timeout periods, the call is disconnected.
By default, RAS 1500 autodetects the authentication method the remote
computer is using (CHAP or PAP). RAS 1500 first attempts CHAP, then PAP
authentication. If the remote computer does not support one of these
methods, RAS 1500 drops the call.
If the PPP link to RAS 1500 succeeds, the message appears on Gina’s
screen as shown in Figure 10.

Network User Case
Study
In this case study, a network user is configured for the IP protocol. This
user's IP address is assigned by RAS 1500, and session and idle timeouts
are specified.
Assumptions This case study assumes the following:
■
A Windows 95 Dial-Up Networking session was made, and the client
Network settings were configured.
■
RAS 1500 uses the correct IP address and netmask.
■
The IP network is configured.
