Case Study A small office satellite provides dial-up connections to its at-home
workers using the RAS1500. All the modems have CLID security enabled,
and the user records have the caller ID fields set. This ensures the workers
can dial in only from home. Additionally, on-demand networking is set up
to call the main office's RAS1500. The main office user profile for the SOS
has CLID callback set so that the main office calls the SOS back to reduce
tariff charges for the LAN-to-LAN connection.
Network Callback
User Case Study
In this case study, a network/callback user is configured for the IP
protocol. This user's IP address is negotiated , phone and alternate phone
numbers provided, and session and idle timeouts specified.
Assumptions This case study assumes the following:
■
A Windows 95 Dial-Up Networking connection was created, and
Network settings were configured for the client.
■
RAS 1500 uses the correct IP address and netmask.
■
The IP network is configured.
■
All other settings remain at factory defaults.
How to Configure
this User
Use the following steps to configure the user:
1 Add a user “Gina” of the network/callback type.
add user gina password 1234 type network,callback
Because the default network service for network users is PPP, do not set
the value.
2 Enter phone and alternate phone numbers at which RAS 1500 calls Gina
back.
set user gina phone 5085524438 alter 5085527867
3 Gina’s home computer has an IP address configured on it. RAS 1500
detects this address by setting the address selection method to
negotiate
.
set network user gina address_selection negotiate
4 Add idle and session timeouts to limit Gina’s time on the line.
set user gina idle_timeout 40000 session_timeout 40000
