Lesson 2: Configuring Inbound Connections

In Windows 2000 Professional, all of the processes for creating network connections are consolidated in the Network Connection wizard. Inbound connections are one of the types of network connections that you can create by using the Network Connection wizard.

After this lesson, you will be able to

• Configure inbound connections in Windows2000.
• Configure remote access to allow incoming VPN connections.

Estimated lesson time: 20 minutes

Allowing Inbound Dial-up Connections

To configure and administer inbound connections on a computer running
Windows 2000 Professional, you use the Network and Dial-up Connection
wizard. To access the Network and Dial-up Connection wizard, click Start, point to Settings, click Network And Dial-Up Connections, and then double-click Make New Connection. The Welcome to the Network Connection wizard will appear. Click Next to continue, and the Network Connection Type page appears. Select Accept Incoming Connections (see Figure 21.1).

Figure 21.1 The Network Connection Type page

Configuring Devices for Incoming Connections

Once you have selected Accept Incoming Connections, click Next. The Devices For Incoming Connections page appears, so you can choose one of the available devices on your computer to accept incoming calls. If the device you select is configurable, click the Properties button to configure it. For example, if you have selected a modem, possible options to configure include port speed, compression, and the type of flow control. (See Figure 21.2.) The Advanced tab contains additional configurable options that might include the number of data bits, the parity, and the number of stop bits.

Allowing Virtual Private Connections

When you are through configuring the device, click OK to close the Properties dialog box and then click Next on the Devices For Incoming Connection page. The Incoming Virtual Private Connection page appears. Select either to allow or not allow virtual private connections, and then click Next.

Specifying Users and Callback Options

You must specify the users who can access this inbound connection on the
Allowed Users page shown in Figure 21.3.

Figure 21.3 Specifying the users who can access this inbound connection

After you select a user, click Properties and click the Callback tab to set the
callback options. You can select Do Not Allow Callback, Allow The Caller To
Set The Callback Number, or Always Use The Following Callback Number.
Enabling callback causes the remote server, in this case your computer, to disconnect from the client calling in, and then to call the client computer back.

By using callback, you can have the bill for the phone call charged to your phone number rather than to the phone number of the user who called in. You can also use callback to increase security. If you specify the callback number, you don't have to worry about someone trying to break in. Even if an unauthorized user calls in, the system calls back at the number you specified, not the number of the unauthorized user.

Selecting Networking Components

After you specify the callback options, click Next, and the Networking Components page appears. You can choose the networking components you want to
enable for incoming connections. You can also install additional networking components by clicking Install. For example, to install NWLink IPX/SPX/NetBIOS Compatible Transport Protocol, click Install, select Protocol, and then click Add. On the Select Network Protocol page, select NWLink IPX/SPX/NetBIOS Compatible Transport Protocol, insert the Windows 2000 Professional CD-ROM in the CD-ROM drive, and then click OK. Windows 2000 installs the protocol.

After the protocol is installed, you are returned to the Networking Components page. When you click Next, you will be prompted to type a name for the connection, and then you should click Finish. If you would like a shortcut to appear on your desktop, select the Add A Shortcut To My Desktop check box. Click Finish to create the connection.

you can use to test your inbound connection, use a range that includes that address.

1. Click Next.
2. Click Finish to accept the default Incoming Connections in The Connection Will Be Named box.
3. Close the Network And Dial-up Connections window.

In this lesson, you learned that you configure inbound connections in Windows2000 Professional by using the Network Connection wizard. You can choose which of the available devices on your computer you will allow to accept incoming calls, and if these devices are configurable, you can click the Properties button to configure them. You must also specify which user accounts can use the inbound connections. For each user account, you can specify whether to allow callback, and if allowed, whether the caller should be able to specify the callback number or whether you want to set it.
