Configuring WAN connections

• WAN hardware such as modems and ISDN terminal adapters

• call services including filtering and automatic service selection for incoming calls, and access control to remote systems for outgoing calls

• WAN software such as SLIP and PPP

To configure a WAN connection using the Network Configuration Manager, follow these steps:

1. To define and configure a modem, select Hardware Add new WAN device Modem. This adds an entry for the device to the /etc/uucp/Devices file.

   To define and configure an ISDN terminal adapter, select Hardware Add new WAN device Add new WAN device. If outgoing calls are enabled, this adds an entry for the device to the /etc/uucp/Devices file.

   If you want to configure UUCP, PPP or SLIP over a dedicated serial line, see ``Configuring serial ports''.

2. If you want to configure outgoing UUCP, PPP or SLIP connections, select Call Services Outgoing. This runs the Dialup Systems Manager which allows you to define the system to be dialed by adding an appropriate entry to the /etc/uucp/Systems file. You can also set up the login chat script to be used with the remote system, restrict the times at which outgoing calls may be made to it, and specify the retry interval for file transmission by uusched(1Mbnu).

   NOTE: If you want to configure an outgoing PPP link, the PPP Outgoing Connection Wizard will create an appropriate entry in the Systems file for you. You do not need to run the Dialup Systems Manager to do this.

3. If you want to control dial-in access to your system, select Call Services Incoming. This runs the Dialin Services Manager. You can choose to filter incoming calls so that only connections from certain specified telephone numbers are permitted. You can also assign services such as PPP that should be automatically available to incoming calls to a specified telephone number or device.

   ---

   NOTE: You do not need to run the Dialin Services Manager unless you need to filter incoming calls or assign services automatically.

   The facility to obtain the caller's telephone number or the telephone number that was called is sometimes not available with ISDN lines. Your telephone company may provide this service for an additional charge.

4. To set up outgoing or incoming PPP links, and to fine tune the configuration of PPP, select Software Configure PPP to start the PPP Manager.

   To quickly configure the details of an outgoing PPP link to an Internet Service Provider (ISP) or to a remote access server belonging to an organizational intranet, select Wizard Add within the PPP Manager, then select Outgoing -- Internet/Intranet, and click on Start to invoke the PPP Outgoing Connection Wizard.

   To quickly configure a system as a remote access server for incoming PPP access by remote users, select Wizard Add within the PPP Manager, then select Incoming -- Remote Access Server, and click on Start to invoke the PPP Incoming Connection Wizard.

   To configure incoming and outgoing SLIP links, select Software Configure SLIP.
