Figure 2-5 shows an example internet configuration using only AppleTalk Phase 1 routing on two Ethernets and two LocalTalk networks.
gateway 2 will be installed second, and will acquire seed configuration data on its EtherTalk Phase 1 interlace.

gateway 3 will be installed last. It will acquire seed data on its LocalTalk interface.
The three gateways in this example will be configured for AppleTalk Phase 1 routing. The first gateway (gateway 1) will be explicitly configured with the proper network numbers and zones. Gateway 2 will acquire seed configuration data on its EtherTalk Phase 1 interface, and gateway 3 will acquire seed configuration data on its LocalTalk interface.

Figure 2-6. AppleTalk Phase 1 Zones and Net Numbers For each of the three gateways to be configured, you should follow the general procedure described in Chapter 1; that is, connect one FastPath to one Macintosh via LocalTalk, configure it as described below, tum it off, unplug it, and move it to its permanent location.
Explicit configuration: gateway 1
After connecting the FastPath to a Macintosh via LocalTalk, launch the FastPath Manager, and select and open the gateway.
In the main configuration dialog box,
•
Click the Reset button, then open the gateway again.
Click the Pause button.
Turn on Options 17 and 18.
Enter the AppleTalk configuration data for the network on the gateway's LocalTalk interface.
Select ATalk Phase 1 from the Configuration menu and double-click on the ATalk Phase 1 listing in the
Configuration area.
Enter the EtherTalk Phase 1 configuration data.
Tum on the Remote Boot switch (optional).
Download K-STAR.
Click the Go button.
Save the configuration data in a file (optional).
This example uses the internet configuration shown in Figure 2-6. For your site, you should determine the proper network numbers and zone names for the gateway before you configure it.
Option 17: ON
Option 18: ON
LocalTalk Interface Zone Name: meredith LocalTalk Interface Net Number: 30 , EtherTalk Phase 1 Zone Name: harvey
EtherTalk Phase 1 Net Number: 10
Note that zones are primarily intended for user convenience and for managing AppleTalk services (such as LaserWriters or AppleShare servers). You should choose zone names that will be meaningful to users to indicate where the services are located.
After selecting Reset and then Pause,
1. Click the Options ... button in the main configuration dialog box. This brings up the Options window.
2. Turn on Option flag 17 and Option flag 18 by clicking in the selection box next to the numbers 17 and 18 (an X appears in the selection box when the option flag has been turned on), then click OK to close the Options window.

Click the Save button to save the configuration file to disk.
At this point, Quit the FastPath Manager (using the File menu), tum off the FastPath, unplug it, and move it to its permanent location on the internet. When you bring up the gateway on the internet, launch the FastPath Manager on a Macintosh on either side of the gateway, and select and open the gateway.
Click Log ... to open the Log window:
These messages indicate that both Option 17 and Option 18 are enabled. This means that the gateway is routing AppleTalk Phase 1 packets (no AppleTalk Phase 2 packets will be processed.)
