Internetworking Over Dial-Up and VPN Connections


When you use a dial-up or Virtual Private Networking (VPN) connection to reach a remote network with non-Windows servers, you must be sure that the remote servers' protocols are carried over the connection. In this section, I'll refer to dial-up connections, but whatever I say applies to VPN connections as well.

The AppleTalk protocol is not transmitted over a Windows dial-up connection. You can reach Macintosh file servers only if the remote network uses the file and print services for Macintosh gateway service on a Windows 200x or NT server, or, if the Macintosh computers use a Windows-compatible TCP/IP-based protocol.

UNIX, and NetWare servers can be reached as long as the appropriate protocol (TCP/IP and IPX/SPX, respectively) is enabled across the dial-up connection. To confirm whether the protocols are enabled, do the following:

1.

Click Start, Connect To, right-click the connection name, and select Properties. You can also open the connection properties from the View Network Connections window.

2.

Select the Networking tab, and verify that the required protocols are checked under This Connection Uses The Following Items.

The protocols must also be enabled on the Dial-Up Networking server at the remote end. If you enable incoming connections on your own Windows XP Professional computer, verify that the protocols are enabled for your Incoming Connections icon.

NOTE

For more information about enabling incoming connections to your computer, see Chapter 18, "Windows Unplugged: Remote and Mobile Networking."


To enable alternative protocols for incoming connections, follow these steps:

1.

View Network Connections by clicking Start, My Computer, My Network Places, View Network Connections.

2.

Right-click the Incoming Connection icon, and select Properties.

3.

Select the Networking tab, and verify that the required protocols are checked under Network Components.

4.

Select the name of each protocol in turn. Click Properties, and confirm that Allow Callers to Access My Local Area Network is checked.

These steps ensure that all protocols are routed through your computer when you dial in by modem or through a VPN connection.
