Configuring Additional Inbound Call Options

You can also configure the following inbound call options:

• Inbound Call Processing ---Controls the processing of inbound connection attempts. When Disabled is selected, no inbound connections are allowed. If a modem is attached to the interface, it is initialized not to answer when called.

  Disabling inbound calls on an interface is a good way to reserve the interface for outbound call attempts.

• Local System ID for CHAP ---Provides a common local system ID that can be used by multiple connected NetWare Link/PPP systems that are using CHAP authentication. This option allows a remote system to maintain a single CHAP authentication secret instead of having to maintain a separate CHAP authentication secret for each local system.

  Note that the Local System ID for CHAP parameter is used only for CHAP challenges issued to remote systems that are calling in. The local system ID specified in the WAN call destination configuration is used for the name field value in a CHAP response to authenticate a local system to a remote system.

• Authentication Database Name ---Maintains caller authentication information in named databases. Each interface can have a unique database, or multiple interfaces can share a single database. Each database can contain any number of inbound authentication entries. By default, all NetWare Link/PPP interfaces share a single database name of PPP-AUTH.
• Authentication Database ---Accesses the inbound authentication database specified in the Authentication Database Name parameter. You can select an inbound authentication entry from the list, then delete, view, or edit it. You can also create new entries. New entries use a remote system ID from the list or a new remote system ID you create by pressing Ins while in the Remote System ID list.

How to Configure Additional Inbound Call Options

To configure inbound call processing, modify the authentication database name, or modify authentication database contents, complete the following steps:

1. Load NIASCFG, then select the following parameter path:

   Select Configure NIAS > Protocols and Routing > Network Interfaces

2. Scroll to a configured PPP interface, then select it.

   The PPP Network Interface Configuration menu is displayed.

3. Select Authentication Options .

   The PPP Inbound Authentication Options menu is displayed.

4. Do one or more of the following:

   To configure inbound call processing, select Inbound Call Processing, then select Enabled or Disabled from the pop-up menu.

   To configure a common local system ID for CHAP authentication, select Local System ID for CHAP, then enter a unique name of up to 45 alphanumeric characters.

   To configure a common local system ID for multiple NetWare Link/PPP systems using CHAP for authentication, select Local System ID for CHAP, then enter a unique alphanumeric name.

   If your network configuration consists of multiple routers and third-party PPP systems, using a common local system ID for CHAP minimizes authentication processes and is easier to maintain.

   To modify the authentication database name, select Authentication Database Name, then enter a new name of up to eight characters.

   To modify the authentication database contents, do the following:

   • Select Authentication Database .
   • To modify an existing entry, select a remote system ID from the list displayed in the pop-up menu, then enter a new password.

     To delete an existing entry, select a remote system ID from the list displayed in the pop-up menu, then press Del .

     To create a new entry, press Ins , enter a new remote system ID of up to 47 ASCII characters, then enter a password.

5. Press Esc to return to the Internetworking Configuration menu; save your changes when prompted.

6. If you want these changes to take effect immediately, select Reinitialize System .

   If you want to configure other parameters, do so now, then reinitialize the system when you are finished.
