This article is the Apple IP Gateway 1.0.1 ReadMe file.
DISCUSSION
This document provides late-breaking information not covered in the "Apple IP Administrator's Guide." It's a good idea to print this document and keep it with the guide.
This Read Me contains the following sections:
* INSTALLING THE GATEWAY ON NON-U.S. SYSTEMS
* USING MANUAL MACTCP ADDRESSES WITH APPLE REMOTE ACCESS CLIENTS
* TROUBLESHOOTING NETWORK ERRORS ON THE GATEWAY
* SETTING UP MULTIPLE GATEWAYS IN THE SAME ZONE
* TUNING THE APPLE IP GATEWAY
* LOCATING THE SNMP MIB FOR THE APPLE IP GATEWAY
* INSTALLING APPLE IP GATEWAY ON APPLESHARE 4.0
* INSTALLING APPLE IP GATEWAY ON OPEN TRANSPORT
* BUG FIXES/CHANGES IN THIS RELEASE
INSTALLING THE GATEWAY ON NON-ENGLISH LANGUAGE SYSTEMS
------------------------------------------------------
If you are installing the Apple IP Gateway on a non-English language Mac OS computer, you should run the Network Software Installer before proceeding with the rest of the installation process. See the section "International Users" in Chapter 2 of the "Apple IP Gateway Administrator's Guide" for details.
Apple recommends that you use Easy Install to install the gateway software on a non-English language Mac OS computer. If you use Custom Install, a message appears to warn you that continuing the installation replaces local-language versions of some AppleTalk system files (such as the Network control panel, AppleTalk, and EtherTalk) with English-language versions. If you click Continue, the installation will replace all files with the same names as the files being installed. Thus, there may be two different versions of some AppleTalk system files on the startup disk-a local-language version and an English version. If you click Cancel, a message informs you that an error has occurred during installation, and the software on the startup disk was not changed.
USING MANUAL MACTCP ADDRESSES WITH APPLE REMOTE ACCESS CLIENTS
--------------------------------------------------------------
If an Apple Remote Access (ARA) client is using a manual (static) IP address, the ARA connection must be established before MacTCP is opened in order for TCP/IP application programs to work over the remote link. To ensure that MacTCP is not opened before the ARA connection, INITs that open MacTCP at startup of the Macintosh (such as SNMP TCP/IP Transport) should be removed from the user's system folder. Users who require such INITs must configure MacTCP to acquire an automatic (dynamic) IP address.
TROUBLESHOOTING NETWORK ERRORS ON THE GATEWAY
---------------------------------------------
Network errors in the Gateway Information window (see the section "Monitoring the Gateway" in Chapter 3 of the "Apple IP Gateway Administrator's Guide" for details), may indicate that the domain name server (DNS) information is misconfigured on either the gateway machine or on client machines. If the gateway cannot find a DNS server, whether because the address is misconfigured or the server is unavailable, the gateway counts those failed attempts as network errors. If you do not have a DNS server, leave the DNS information blank in the MacTCP Administration window.
SETTING UP MULTIPLE GATEWAYS IN THE SAME ZONE
---------------------------------------------
You can set up multiple Apple IP Gateways in the same AppleTalk zone. Doing so allows you to balance the gateway service load between multiple machines, as well as to provide service to an additional 253 users per gateway.
To set up multiple gateways, you must configure the gateway to provide automatic addresses only; you cannot use manual addresses with multiple gateways. Also, Power Macintosh clients will not be able to locate a gateway if there are multiple gateways in a zone. Only MacTCP clients on non-Power Macintosh machines will be able to locate a gateway if multiple gateways are in use.
Follow these steps to set up multiple gateways in the same zone:
1) Purchase another copy of the Apple IP Gateway and install it on another
machine.
2) Set up the second gateway machine in the same zone as the original
gateway.
3) Divide the automatic address range of the original gateway into two
ranges. Configure the original gateway with one of these ranges and
the second gateway with the remaining range.
4) Start both gateways.
Clients connect to the first gateway that responds. When a gateway has no more addresses to give out, it ceases responding, thus allowing another gateway to respond to the client.
IMPORTANT: If you have Power Macintosh clients that need to access a gateway, do not set up multiple gateways in the same zone.
TUNING THE APPLE IP GATEWAY
---------------------------
If you are an experienced network administrator and would like to modify the gateway's internal parameters to suit your particular networking environment, you can obtain an Apple Business Systems (ABS) Technical Note that describes which parameters you can modify through use of a Macintosh software resource editor such as ResEdit. The document, entitled "IPGateway01 Tuning the Apple IP Gateway," is available through the following electronic sources:
* FTP: anonymous ftp to abs.apple.com, directory ~ftp/abs/
* AppleLink: through the path, Support/Developer Support/Developer
Services/Technical Documentation/ABS Technical Notes
* Developer CD: Technical Documentation/ABS Technical Notes (on the
reference library disk)
LOCATING THE SNMP MIB FOR THE APPLE IP GATEWAY
----------------------------------------------
The gateway supports the SNMP MIB entitled "MacIP Management Information Base," which is available in the appendix of the "Apple IP Gateway Administrator's Guide" or electronically (in text form) on the "Apple IP Gateway Installer" disk 2, Network Management folder.
INSTALLING APPLE IP GATEWAY ON APPLESHARE 4.0
---------------------------------------------
Apple IP Gateway installs Apple Shared Library Manager 2.0, which is not compatible with AppleShare 4.0. If you intend to run Apple IP Gateway and AppleShare 4.0 on the same Macintosh, upgrade to AppleShare 4.0.2 before installing the Apple IP Gateway.
INSTALLING APPLE IP GATEWAY ON OPEN TRANSPORT
---------------------------------------------
Apple IP Gateway cannot be installed on a machine running Open Transport.
BUG FIXES/CHANGES IN THIS RELEASE
---------------------------------
- Two clients connected to the same IP Gateway can talk to each other.
- The IP Gateway now works with external SCSI Ethernet devices.
- The Gateway does not allow the user to enter overlapping Static and
Dynamic address ranges.
- The Gateway detects when a client with a static IP address changes its
AppleTalk address as may occur when the client restarts.
- The Gateway Manager displays Macintosh names and AppleTalk addresses
sorted in the correct order.
- A probl
em with Balloon help was fixed.
