This section describes configuring the Connection Services Manager (CSM) software for the example Windows
Dial-up application shown earlier in
Section 6.1
. This would include:
• Establishing a pool of IP addresses to be temporarily assigned to remote devices. The PC using Windows 95
dial-up networking will be one of these remote devices.
• Defining the Concentrator as an access server and establish authentication parameters. We will identify
the IP-address pool we wish to use with the Concentrator.
• Identifying the remote PC (the one using Windows Dial-up Networking) as a remote device.
(If we were using RADIUS rather than CSM, the values we would need to set would be the same, but the
procedures would be different—consult the RADIUS documentation.)
Here’s what the procedure would be for our hypothetical network. To begin, we’d start up the CSM
Connection Manager and make a connection (File/Connect). Then we’d proceed with the following steps:
1. From Configure on the CSM Connection Manager menu bar, select IP Information.
2. Enter the user-defined IP pool name (“LRA3_ip_pool”).
3. Enter a Start IP Address of 2.2.2.11.
4. Enter an End IP Address of 2.2.2.25. Note that this range of addresses is limited to the same subnet,
and that the number of addresses (15) does not exceed the number of available ISDN connections (23).
5. Click Create New Pool.
6. From Configure on the menu bar, select Access Servers.
7. Click Add to configure CSM for the Concentrator. This will place you in the Properties window:
a. Under Name, enter “Conc_LRA3”.
b. Provide the Concentrator’s IP address (2.2.2.1).
c. In the Access Server Type field, select “LRA3000”.
d. Provide authentication information: the CSM Secret (“CSM_sec”) and System Secret (“LRA3_sec”).
These values correspond to the values we already entered on the Concentrator (see
Section 6.1.1
).
8. Select the Demand Access tab. Since we plan to use an IP address pool, select the IP Pool name of
“LRA3_ip_pool” from the pull-down list. We do not need to change the Group field since we did
not set up groups.
9. Click Add.
10. From Configure on the menu bar, select Devices.
11. Click Add to add the remote PC.
12. Under the Address tab, specify the device name of “Rem_PC”.
13. Under the Protocols tab:
a. Enable IP;
b. Check the Dynamic Address Assignment box (since we will be using the IP-address pool for this device);
c. Select “LRA3_ip_pool” from the pull-down box in the IP pool field.
