1 About the Apple IP Gateway The Apple IP Gateway provides Macintosh computers on an AppleTalk network access to services on an Internet Protocol (IP) network—even if the computers themselves are on an AppleTalk system that does not directly support IP. Thus the gateway is particularly useful for Macintosh computers connected by LocalTalk cabling or through Apple Remote Access. The Apple IP Gateway can be installed on a wide range of Macintosh computers.
About IP networks The Internet Protocol (IP) and its companion, the Transmission Control Protocol (TCP), were first developed as part of a United States defense research effort some twenty years ago. Since then, TCP/IP has become the international standard for heterogeneous networking, in which many different computer types can interoperate and share information and services. TCP/IP can be used for local area networking, in which, for example, clients access data from a UNIX® host.
How the gateway works On both AppleTalk and IP networks, data is broken down into packets for transmission. The two network types use different sets of rules—protocols— for packet construction and for addressing packets to their correct destinations. Data can’t ordinarily cross from one network type to the other. The Apple IP Gateway solves this problem.
Client Macintosh running MacTCP tw or k 1. Client sends IP packets enclosed in Datagram Delivery Protocol “envelope.” Ap pl eT alk ne 2. Gateway strips off DDP envelope. 3. IP packets continue on to the IP network.
How the gateway can be used Depending on the type of AppleTalk network you are working with and the needs of your network users, you can run the gateway as a stand-alone product, or you can use the software in conjunction with either the Apple Internet Router or an Apple Remote Access Personal or MultiPort Server. Using these options is covered in detail in Chapter 3, “Operating and Monitoring the Apple IP Gateway.” The descriptions that follow give you an idea of overall functionality.

Macintosh running Apple Internet Router and Apple IP Gateway Figure 2 Combining an Apple Internet Router with the Apple IP Gateway lets you offer gateway services to all Macintosh computers served by the router. The Apple Internet Router and the Apple IP Gateway software can run on the same computer, although they do not have to.
The Apple IP Gateway and the Apple Internet Router AppleTalk/IP Wide Area Extension Although it is easy to confuse the Apple IP Gateway and Apple Internet Router AppleTalk/IP Wide Area Extension, the two software programs actually provide two completely different services. The Apple IP Gateway allows Macintosh computers on an AppleTalk network to communicate with computers of many different types on an IP network.

Using the gateway with an Apple Remote Access server Apple Remote Access software creates a remote extension of an AppleTalk network, with packets transmitted over telephone lines rather than over dedicated cables. Users who dial into an AppleTalk network through an Apple Remote Access Personal or MultiPort Server can access all network services as though they were locally connected.

The Apple IP Gateway and the AppleSearch WAIS Gateway AppleSearch 1.5 includes a WAIS Gateway that allows AppleSearch clients to search WAIS (wide area information server) computers on the Internet. Like the Apple IP Gateway, the WAIS Gateway requires a Macintosh with both AppleTalk and IP connections. The two gateways can run on the same machine, thus giving users the benefits of both approaches. However the benefits are different and should not be confused.
Hardware and software requirements The Apple IP Gateway may be installed on any Macintosh II or later Macintosh computer that is equipped with m Ethernet on the IP side If the gateway computer does not support NuBus™, it must have built-in Ethernet, a processor-direct slot (PDS) card, or a SCSI adapter. See the documentation supplied with the card or adapter for full information on installation, setup, and operation.
2 Installation and Setup This chapter covers all available options for installation of the Apple IP Gateway and describes the procedures for each. Proper setup varies according to network administrator preference and the kind of access you want to offer network users. Setup procedures require coordination between the Apple IP Gateway software itself and the MacTCP software on the gateway computer. This chapter shows you how to make them work together to achieve the desired result.
International users If you are installing the Apple IP Gateway on a non–United States Macintosh computer, you should run the Network Software Installer (NSI) before proceeding with the rest of the installation process. The NSI installs the latest international versions of all networking software. The Network Software Installer disk is supplied in your Apple IP Gateway package. Before running the NSI, you should make a backup copy of its disk.
3 Click OK. The Easy Install dialog box appears: 4 If necessary, click Switch Disk until the name of the disk you want to install on appears. The Easy Install process is preset to install all the networking software contained on the Network Software Installer disk onto your current startup disk. By switching disks, you can install the networking software on any hard disk that has a System Folder. IMPORTANT You must install the networking software on the same disk as the Apple IP Gateway.
Clicking Continue automatically quits all open programs and begins the installation. Clicking Cancel quits the Installer and leaves your hard disk unchanged. The Installer begins the installation process, with on-screen messages reporting its progress. You can cancel the installation at any time, leaving the hard disk unchanged. 6 When you see a message reporting that installation was successful, click Restart.
2 Click Customize. The Customize dialog box appears: 3 If necessary, click Switch Disk until the name of the disk you want to install on appears. The Customize option is preset to install the designated networking software onto your current startup disk. By switching disks, you can install the networking software on any hard disk that has a System Folder. IMPORTANT You must install the networking software on the same disk as the Apple IP Gateway. 4 Select the software you want to install.
5 Click Install to place the networking software on your hard disk. If other programs are currently running on your computer, the following dialog box appears: Clicking Continue automatically quits all open programs and begins the installation. Clicking Cancel quits the Installer and leaves your hard disk unchanged. The Installer begins the installation process, with on-screen messages reporting its progress. You can cancel the installation at any time, leaving the hard disk unchanged.
Installing the gateway software Before installing your gateway software, you should make a backup copy of the installation disks, the Apple IP Gateway Installer 1 and Apple IP Gateway Installer 2, which you will find in the Apple IP Gateway package. Put the originals aside for safekeeping, and use the backups for installation. This section describes the Easy Install procedure that Apple recommends as well as the Custom Install procedure that you may want to use instead.
2 Double-click the Installer icon to open the Installer program. An informational dialog box appears. 3 Click Continue. The Installer dialog box appears, set for Easy Install. When you click Install, the Installer automatically creates a folder on your startup disk called Apple IP Gateway and installs the Gateway Manager in that folder. It also automatically installs all other gateway software in the System Folder on your current startup disk.
proceed to step 4. If you want to install the Gateway Manager in an alternate location, or if you want to install the gateway extensions into a different System Folder, you should now follow the procedures in “Designating Software Locations,” later in this chapter. When you have completed those procedures, return here and go on to step 4. 4 Click Install to place the Apple IP Gateway software on your hard disk.
Using Custom Install Custom Install allows you to pick and choose which files you want for installation. The following software is the minimum necessary for the gateway to run successfully: m the Apple IP Gateway software, including the Gateway Manager and MacTCP version 2.0.4 or later m AppleTalk version 58.1.
3 Click Continue. The Installer dialog box appears, set for Easy Install. 4 Choose Custom Install from the pop-up menu at the top of the Installer dialog box. Note: The Custom Remove option allows you to remove installed files should this ever prove necessary.
The Custom Install dialog box appears. The Installer is set to create a folder on your startup disk called Apple IP Gateway and to install the Gateway Manager in that folder. It automatically installs all other gateway software in the System Folder on your current startup disk. If you want to use those default locations, proceed to step 5.
Click OK when you’re done reviewing the informational window. 6 Click Install to place the selected software on your hard disk. If other programs are currently running on your computer, the following dialog box appears: Clicking Continue automatically quits all open programs and begins the installation. Clicking Cancel quits the Installer and leaves your hard disk unchanged. The Installer begins the installation process, with on-screen messages reporting its progress.
7 When you see a message reporting that installation was successful, click Restart. Designating software locations The Installer automatically installs the Gateway Manager on the current startup disk in a folder called Apple IP Gateway. The Installer places all other gateway software in the System Folder of the current startup disk. You can change these automatic locations using the Destination Folder section of either the Easy Install or the Custom Install dialog box.
Note: The process is the same whether the Installer is set for Easy Install or Custom Install. The Folder Selection dialog box appears: 2 Using standard folder navigation techniques, locate the folder and hard disk for installation. If you have any questions about folder navigation, see the documentation that came with your Macintosh computer. You can navigate to any folder or connected hard disk.
3 Designate a folder for the Gateway Manager installation. You can select any folder on any hard disk, or you can create a new folder using the following procedure: a. Click the New Folder ( ) button on the right side of the dialog box. The New Folder dialog box appears: b. Type the name of the new folder. c. Click Create. 4 Click the Select “” button at the bottom of the dialog box. When you click Install, the Gateway Manager will be installed in this folder.
Note: The process is the same whether the Installer is set for Easy Install or Custom Install. The System Disk dialog box appears: 2 Choose a system disk from the pop-up menu. 3 Click OK. The gateway software will be installed on the designated system disk. Setting up the gateway To set up the Apple IP Gateway, you first configure your MacTCP software, after which you configure the gateway itself.
After you double-click the icon, the Gateway Information window and menus appear. 2 Choose “Set up MacTCP” from the Control menu. Alternatively, choose Control Panels from the Apple menu and double-click the MacTCP control panel icon in the window that appears.
With either method, the MacTCP control panel opens. 3 Click an Ethernet icon in the upper section of the control panel. If you have multiple Ethernet connections, select the one that is connected to the IP network. The gateway will not run if you select EtherTalk or any other type of AppleTalk network connection. 4 Click More. The Administrator dialog box appears.
5 Click Manually in the Obtain Address section of the dialog box, then click OK to return to the MacTCP control panel. 6 Enter the IP address of the gateway computer in the lower section of the control panel. Obtain this address from your network administrator and type it exactly as specified. 7 Click More.
10 Enter the gateway address in the Routing Information section of the dialog box. This is the address of the IP router that routes packets from your local IP subnet to other IP subnets. Don’t confuse this with the Apple IP Gateway itself. Obtain the address from your network administrator. 11 Click OK. The Administrator dialog box closes and the MacTCP control panel reappears. 12 Click the control panel close box. If you are setting up MacTCP for the first time, the control panel closes.
With either automatic or manual addressing, you specify a range of IP addresses that the gateway can provide, either dynamically or permanently. Automatic addressing allows you to limit the number of clients that can access the server at any one time. Manual addressing allows you to limit both the number of clients and the specific group of clients who have access. If you use both manual and automatic addressing at the same time, you must specify two separate ranges, one for each type.
3 Click the radio button that represents your addressing choice. You can configure for automatic addressing, manual addressing, or both. 4 Specify the number of addresses. m If you are configuring for automatic addressing only, enter a value from 1 to 253 in the upper “Number of addresses” text box. m If you are configuring for manual addressing only, enter a value from 1 to 253 in the lower “Number of addresses” text box.
Obtain these addresses from the network administrator. The end of the range is automatically determined by adding the number of addresses permitted to the starting address. You can perform steps 4 and 5 in either order. The result is the same. IMPORTANT If you are using both manual and automatic addressing, be sure that the address ranges do not overlap. The Apple IP Gateway cannot manage automatic and manual addresses from the same range.
Hardware and software requirements Most Macintosh computers in current use are adequate for accessing the Apple IP Gateway. Minimum requirements are: m any Macintosh Plus or later Macintosh computer m a minimum of 2 megabytes of RAM m system software version 6.0.5 or later m MacTCP version 1.1 or later m AppleTalk version 57.
The following configuration information can serve as your guide if you are planning to distribute configured software. If users will be configuring their own software, you may find it convenient to photocopy one or both of these sets of directions and hand them out as appropriate. Configuring MacTCP for automatic addressing To configure the software for automatic addressing: 1 Choose Control Panels from the Apple () menu. The Control Panels window opens.
3 Click the AppleTalk connection icon in the upper-left corner to select it (if it isn’t selected already). This icon indicates the connection method that your computer is currently using. The connection method is set in the Network control panel, shown in the following figure, and the MacTCP setting is determined by that setting. Note: If your computer has only one connection method, you may not have a Network control panel. In this case, only one icon appears in the MacTCP control panel window.
You do not need to enter an address. 5 Click More. The Administrator dialog box appears.
6 Click Server in the upper-left section of the dialog box. You do not need to enter a gateway address or any address class or subnet information. 7 If necessary, enter the domain name server information in the lower-right section of the dialog box. If you do not enter information, the gateway computer will supply it to your computer. If you want to use more than one domain name server, it is useful to enter the domains and addresses. Obtain this information from your network administrator. 8 Click OK.
Configuring MacTCP for manual addressing To configure the software for manual addressing: 1 Choose Control Panels from the Apple () menu. The Control Panels window opens. 2 Double-click the MacTCP control panel to open it. The following window appears: 3 Click the AppleTalk connection icon in the upper-left corner. The icon indicates the connection method that your computer is currently using.
Note: If your computer has only one connection method, you may not have a Network control panel. In this case, only one icon appears in the MacTCP control panel window. When you select the icon, a pop-up menu of zones appears beneath it. (On some LocalTalk networks there are no zones. If this is the case, you can skip step 4.) IMPORTANT Remote Access clients need to be connected to the Apple Remote Access server for the zone menu to appear.
5 Click More. The Administrator dialog box appears. 6 Click Manually in the upper-left section of the dialog box, and then click OK. The MacTCP control panel reappears. 7 Type the assigned address for this client in the IP Address text box. The address must be one of the addresses in the designated manual range. 8 Click More. The Administrator dialog box reappears, with address and class information now filled in.
11 Click OK. The Administrator dialog box closes and the MacTCP control panel reappears. 12 Click the control panel close box. If you are setting up MacTCP for the first time, the control panel closes. If you changed the configuration, and have used MacTCP with another configuration and have not restarted the computer since then, you will see a dialog box informing you that you will need to restart the computer to put your changes into effect. 13 Restart the computer if necessary.
3 Operating and Monitoring the Apple IP Gateway Once the Apple IP Gateway and MacTCP have been successfully configured, operation is straightforward, whether the gateway is used on its own or in conjunction with the Apple Internet Router or an Apple Remote Access MultiPort or Personal Server. There are, of course, problems that can come up. These are covered in Chapter 4, “Troubleshooting.
Starting and stopping the gateway You start and stop the Apple IP Gateway from the Gateway Manager program. To start the gateway: 1 Open the Gateway Manager program. The Gateway Information window opens. 2 Click Start or choose Start Gateway from the Control menu. The gateway automatically begins to run. You can see the level of activity from the Gateway Information window. The information in the window is discussed later in the next section, “Monitoring the Gateway.
Monitoring the gateway There are two main ways to monitor the gateway: with the statistics gathered in the Gateway Information window and with SNMP. Viewing gateway statistics The Gateway Manager window presents a dynamic picture of the gateway in operation.
The window monitors the gateway continuously. If you want to see its operation from a particular moment, choose Reset Statistics from the Control menu. This sets all activity values to zero, including any variables monitored with SNMP, and begins counting them again. Using MacSNMP The Apple IP Gateway Installer automatically installs an SNMP agent on the gateway computer.
m details about all mounted volumes m details about the currently selected printer If you want to institute remote monitoring, you will need to purchase an SNMP console, available from a number of vendors. Again, interested readers are referred to the MacSNMP Administrator’s Guide, and especially to the technical references listed therein.
3 Type a password in the “New password” text box. The password appears as dots rather than text. The password can be up to eight characters long, and it can include any combination of upper- or lowercase letters, numbers, or symbols. As with all passwords, the one you choose should be easy to remember and hard to guess. 4 Type the password again in the “Retype new password” text box. 5 Click OK. You will be prompted for the password each time you launch the Gateway Manager.
Limiting network access You can control which networks the gateway will accept users from with the network restrictions feature in the Gateway Setup dialog box. 1 Open the Gateway Manager program. 2 Stop the gateway if it is running. You cannot make changes to gateway setup while the gateway is running. When you click Stop the following dialog box appears: 3 Click OK. 4 Choose “Set up Gateway” from the Control Menu. The Gateway Setup dialog box appears.
5 Click the “Use network restrictions” checkbox to select it, and then click Set Up. The Network Restrictions dialog box appears. 6 Choose the restriction method you want to use. You can choose to hide IP services from only those AppleTalk networks listed or from all AppleTalk networks not listed. The first method is more practical when you want to exclude a small number of networks on your AppleTalk internet from access to IP services.
restrictions for all LocalTalk networks in that set of numbers. You can also pick range numbers that cover only a part of a network. 8 Click Add. The network number appears in the Network List at the top of the dialog box. 9 10 Repeat steps 7 and 8 until you have listed all networks you want to include or exclude. Click OK. The dialog box closes. When you restart the gateway, your restrictions will be in effect.
6 Click Add after each addition. When you click Add, the network is added to the Network List. 7 Click OK when you’re finished. 8 If you want to remove networks from the Network List, click their numbers in the Network List. Shift-click for multiple selections. 9 Click Remove. When you click Remove, the network is deleted from the Network List.
10 Click OK. The dialog box closes. When you restart the gateway, your changes will be in effect. Preventing unauthorized access by IP computers The Apple IP Gateway works in both directions. Just as clients on the AppleTalk side have access to the IP network, IP computers have access to Macintosh computers on AppleTalk networks. Restricting this access cannot be done from the AppleTalk side. It can, however, be accomplished with most IP routers.
4 Troubleshooting The Apple IP Gateway links two complex network systems. Therefore operational errors are inevitable. This chapter suggests a basic approach to troubleshooting problems. Following that, the chapter lists some of the most common problems, along with ways to remedy them. Be aware, though, that if you are using the Apple Internet Router or an Apple Remote Access server with the gateway, the problem may lie with that software, rather than with the gateway itself.
Diagnosing and solving problems The following steps outline a troubleshooting strategy that you can use to isolate and solve problems as they come up. 1 Determine the symptoms. Gather information from users to define the nature of the problem. If users are reporting multiple problems, handle each one separately. 2 Determine whether the network is the source of the problem.
m Determine whether the gateway Macintosh is the source of the problem. m Determine whether the Apple IP Gateway software is the source of the problem. 4 Identify the cause the problem. Once you’ve isolated the problem to a specific device: m Verify that all cables are undamaged and connected correctly. m Verify that all software is of the correct version number and has been installed correctly.
A user who has previously accessed the gateway can no longer do so. m The client’s IP address has been assigned to another client by the gateway. Have the user restart the Macintosh to get another address. Note: This will only happen when the gateway is in a different zone than the client and the gateway is restarted after the client is assigned an address.
