The gateway managing a separate IP network:

"Split addressing" with Option 9

In the example configuration shown in Figure 3-10, the gateway is configured as a host on the Ethernet/IP subnet 130.57.64.0, and as a host on a separate class C IP network 192.85.6.0. The client Macintoshes are seen as IP hosts on the separate IP network.

As a side effect of this configuration method, other IP routers need to be informed about the existence of the new network. If routers on the internet support the Routing Information Protocol (RIP), they will automatically be informed by the RIP packets sent out by the gateway. If RIP is not supported on the

internet, you need to update the routing tables on other hosts.

The client Macintosh IP addresses are contiguous with the gateway's IP address on the new IP network; the block of free addresses begins at the IP address specified in the Local Parameter #1 field + 1. Option 9 must be ON.

LocalTalk network supporting 9 Madntoshes runrting TO' /IP software. These Madntoshes wi! be hosts on a class C IP network 192.85.6.0, which is entirely administered within the gateway.

Ethernet/IP network: 130.57.64.0, subnet mask 255.255.255.0 (FFFFFFOO).

The following IP addresses will be available for static assignment to client Macintoshes:

192.85.6.2 192.85.6.3 192.85.6.4 192.85.6.5

Note that these begin at the Local Parameter #1 address +1.

Because you are using a separate IP network number, the address specified in the Local Parameter #1 field is used as the gateway's address on the new network.

The following IP addresses will be available for client

Macintoshes to acquire dynamically as they boot up on the IP network:

1111" This entire range of addresses cannot be duplicated anywhere on the IP internet. In addition, there can be no IP hosts on this IP network other than the gateway and its clients.

In configuring the gateway, you should follow the general procedure described in Chapter 1. After connecting the gateway to a Macintosh via LocalTalk, launch the FastPath Manager, and select and open the gateway. In the main configuration dialog box,

Click the Reset buHon, then open the gateway again.

Click the Pause buHon.

Enter the AppleTalk configuration data; see Chapter 2.

Turn on Option 9 in the Options window.

Select K-STAR IP from the Configuration menu and double-click on the K-STAR IP listing in the

Configuration area.

Enter the IP address of the FastPath Box.

Click More.

•

In the Local Parameters #1 field, type the IP address that will be the gateway's address on the new IP network.

Enter the number of client Madntoshes controlled by the gateway.

Turn 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 3-10. For your site, you should determine the proper addresses for the gateway before you configure it.

Option 9:

IP Address of FastPath Box:

Local Parameter #1 : (Clients) Dynamic:

After selecting Reset and then Pause, enter the AppleTalk configuration you require, as described in Chapter 2. Then proceed with the IP configuration:

1. Click the Options ... button in the main configuration dialog box. This brings up the Options window.

2. Turn on Option flag 9 by clicking in the selection box next to the number 9 (an X appears in the selection box when the option flag has been turned on), then click OK to close the Options window.

-3. Select K-STAR IP from the Configuration menu and double-click on K-STAR IP in the Configuration area to open the IP dialog box.

4. Type 130.57.64.5 in the IP Address of the FastPath Box field, then press tab. This will be the gateway's IP address on the existing Ethernet/IP network.

5. Click More to open another dialog box.

6. Tab twice to position the cursor in the Parameter #1 field, and enter an IP address using a separate IP network number: 192.85.6.1, then press tab.

7. Click OK to return to the previous dialog box.

8. Double-click in the Dynamic field in the ''Number of IP Clients" area, and type the number of client Macintoshes that will dynamically acquire IP addresses from the gateway: 5, then press tab.

9. Type the number of client Macintoshes that will be assigned static IP addresses administered by the gateway: 4, then press tab. The total number of clients supported by a gateway must be less than or equal to 60.

10. Click OK to return to the main dialog box.

11. Tum on the Remote Boot switch by clicking in the selection box.

12. Select Download a File ... from the File menu and open K-STAR.

13. Click the Go button.

14. 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, select and open the gateway, and check the log messages.
