Chapter 3 • Configuring Your 
                     Network Connections

Contents of this Chapter

•  3.1 TCP/IP Connections

•  3.2 AppleTalk Connections

Before configuring InterPPP, you must configure the protocols you are using to connect to the remote network. If you are connecting to a remote network using TCP/IP, see Section 3.1, TCP/IP Connections. If you are connecting to a remote network using AppleTalk, see Section 3.2, AppleTalk Connections.

3.1 TCP/IP Connections

If you need to configure your connection for TCP/IP:

1. Select Control Panels from the Apple menu.

√  The Control Panels window is displayed.

2. Double-click the MacTCP icon (Figure 3.1).

Figure 3.1 The MacTCP Icon

√  The MacTCP dialog (Figure 3.2) is displayed.

Figure 3.2 The MacTCP Dialog

3. Select the TCP/IP PPP icon and enter your PPP account address in 
       the IP Address text field below the icon.

4. Click More….

√  The MacTCP Administrator dialog (Figure 3.3) is displayed.

5. In the Obtain Address box, click either Manually or Server.

            The Dynamically option in the Obtain Address box is not 
              available for use with InterPPP.

•
  Click Manually to set your IP address in the IP Address field in the 
      MacTCP  dialog (where you manually entered it in Step 3  ).

OR

•
   Click Server to have the remote network negotiate your IP address 
       and automatically set MacTCP during each connection.

6. Check that the information is correct in the Routing Information, IP 
       Address, and Domain Name Server Information boxes.

              f you are configuring MacTCP for the first time or need more 
              information on the fields in the MacTCP dialogs, see the About 
             Networking: A Guide to TCP/IP and MacTCP    book included 
              in your InterPPP package. Refer to Part II, Chapter 3, 
            Configuring MacTCP.

7. Click OK to save the MacTCP administrative information. (Or click 
       Cancel to close the dialog without saving any changes.)

√  The MacTCP dialog is displayed. 

8. Click the close box to close the dialog.

√  The warning shown in Figure 3.4 is displayed.

9. Click OK.

√  The Control Panels window is displayed. 

10. Configure your AppleTalk connection, if necessary. See Section 
         3.2, AppleTalk Connections,  for more information.

OR

       Click the close box to close the window.

11. Restart your Macintosh.

            Selecting TCP/IP PPP in the MacTCP dialog disables other 
              network protocols. If you use different protocols
              to connect to a network, such as TCP/IP PPP and Ethernet, 
              reselect the desired protocol before connecting. Be sure to enter 
              the appropriate information, such as your Ethernet IP address.

3.2 AppleTalk Connections

If you need to configure your connection for AppleTalk:

1. Select Control Panels  from the Apple menu.

√ The Control Panels window is displayed.

2. Double-click the Network icon (Figure 3.5).

Figure 3.5 The Network Icon

√ The Network dialog (Figure 3.6) is displayed.

3. Select the AppleTalk PPP icon.

√ The warning dialog shown in Figure 3.7 is displayed.

4. Click OK to change your connection to AppleTalk PPP. (Or click
       Cancel to close the dialog without changing your connection.)

√ The Network dialog is displayed. 

5. Click the close box to close the dialog. 

√ The Control Panels window is displayed. 

6. Configure your TCP/IP connection, if necessary. See Section 3.1, 
    TCP/IP  Connections,  for more information.

OR

       Click the close box to close the window.

            electing AppleTalk PPP in the Network dialog disables other 
             network protocols. If you use different protocols 
             to connect to a network, such as AppleTalk PPP and Ethernet, 
             reselect the desired protocol before connecting.

             f you have configured MacTCP as well as AppleTalk, you must 
             restart your Macintosh for the MacTCP changes to take effect.
