IPNetRouter is a powerful utility for configuring TCP/IP networking under Macintosh Open Transport. The features of IPNetRouter closely follow the underlying features of TCP/IP itself, providing almost unlimited flexibility for building TCP/IP connectivity solutions. If you are only interested in sharing a single Internet connection (dial-up, dsl connection, etc) among several computers, quickly skim down to the "How to Get Started" section below.
IPNetRouter need only be installed on one Mac to make an Internet gateway for other computers. The other computers (Macs, Windows, Linux, Palm OS, etc) may need to be configured to work with your new gateway, but they do not require anything beyond standard TCP/IP networking software.
As with all of our Macintosh software products, IPNetRouter features a fully functional 21 day trial period. Once you are certain that our software is right for the job, a registration key can be purchased for $89 (see our registration page for
educational and 68K only discounts).

If you decide to purchase IPNetRouter, or even if you don't, we also have other software that can enhance a Mac's networking capabilities. Like IPNetRouter, they all come with 21 day free evaluations.
IPNetSentry (IPNS) blocks port scanning automatically without you having to know what that means! Its automatic blocking and enhanced notification features compliment IPNetRouter's IP Filtering and IP Masquerading.
IPNetMonitor (IPNM) provides a suite of integrated Internet tools which allow Macintosh users to verify router operation and performance, including DHCP test tools, a Monitor window to watch packet performance, standard Ping, TraceRoute, NSLookup, Whos and more.
IPNetTuner (IPNT; formerly known as "OT Advanced Tuner") is our Open Transport TCP/IP parameter tweaking tool. It comes with several pre-configured documents which can immediately help you get the most of your existing Internet connection, whether it be a high-speed cable or DSL modem or a slower speed analog modem connection.
You can download any of these software packages from our website:

5. Installation and Removal
If this is your first installation of IPNetRouter, check to see if there is a later general release available on our website before proceeding with configuration.
<http://www.sustworks.com/site/downloads.html>
To install or remove the software, simply run the supplied Installer application.
The Installer application installs a user specified "IPNetRouter" folder that can be moved to the trash at any time. The contents of the folder include:
IPNetRouter application
ReadMe document
International folder (local language versions of the ReadMe document)
License Agreement document
Registration application (Kagi)
Unlink OTModl$Proxy applet
Release Notes document
IPNR_Config folder
In addition, the Installer places an "OTModl$Proxy" shared library file in your Extensions Folder (needed for IP masquerading & filtering, and used by our other applications).
IMPORTANT: On systems prior to OS 9, if you wish to remove the "OTModl$Proxy", please run the supplied ╥Unlink OTModl$Proxy╙ applet to avoid disabling TCP/IP. Once OTModl$Proxy has been unlinked, you can safely move it to the trash. Do not use this applet unless you want to remove/disable IPNetRouter (IPNetMonitor and IPNetSentry) entirely.
You can also use the Installer to uninstall the complete package. Hold the option key down when you see the "Install" button in the Installer application window. Note, this will not remove the entire IPNetRouter folder since "Unlink OTModl$Proxy" is launched from this location. Also, It will not delete OTModl$Proxy in your Extensions Folder (since another application may still require it). To remove these entirely, drag them to the trash after running the uninstaller.
[Technical Note: IPNetRouter actually modifies the currently selected configuration (Cmd-K) in the TCP/IP Preferences file in your System Folder. Once modified, it is critical that the OTModl$Proxy file remain in your Extensions folder since OT won't be able to build this configuration without it. OTModl$Proxy is not really an extension. It's a shared library that is loaded and linked by Open Transport when the corresponding protocol stack is created. You can "unlink" the TCP/IP prefs from the OTModl$Proxy by: (1) Running the "Unlink OTModl$Proxy" applet; (2) Using the supplied Installer to uninstall IPNetRouter; (3) Creating a new TCP/IP configuration (by copying an existing one); or (4) Using ResEdit to edit your TCP/IP Preferences File and remove the 'crpt' or 'blip' resource IPNetRouter added.]

6. Installing Over Another Version of IPNetRouter
The standard installer is designed to install a newer version over a previous one. If you have any trouble, the following steps will insure the application is installed correctly.
(1) Find any previous version of OTModl$Proxy in your Extensions
folder and move it to the trash.
(2) Remove any previous version of the IPNetRouter Application.
(3) Run the correct IPNetRouter installer for your machine (PPC or 68K)
to install the desired version of IPNetRouter.
(4) Restart your computer (this step is very important).
The installer only "suggests" you restart because it
isn't always necessary, but you should do this
if you are not sure.
(f you are just going to re-install the application, don't use the uninstaller. The uninstaller is for removing IPNetRouter completely and makes it harder to re-install. If you do use the uninstaller, here's how to complete the re-install process.)
(5) Hold down the Option key when you launch the IPNetRouter
application the first time after re-installing. Continue
pressing the option key until the application comes up.
This forces Open Transport to rebuild your link stream.
Note: Use this method also if you add or remove an
interface card from your machine.
- or -
Alternatively, configure IP masquerading, and then Restart
your Mac yet again.
The purpose of step (5) is to give Open Transport a chance to rebuild your link stream with the Proxy module inserted. You can verify this was successful if you are able to use the monitor window in IPNetMonitor to monitor data on the interface you will be using to masquerade.
(6) As of January 2001, if you need to reenter the registration info into the application, you may ignore the date field in the registration window.

7. How to Get Started
TCP/IP networking is a vast and complex subject. Unlike many Macintosh applications, you will not be able to guess how it works by casually examining the menus or other controls. Instead we offer two basic ways to get started using IPNetRouter:
(1) A setup wizard called the "IPNetRouter Configuration Application" (IPNR Config) that asks simple questions to walk you through the setup process. IPNR Config is normally included when you install IPNetRouter. You can also download it from our website at <http://www.sustworks.com/site/downloads.html>.
(2) Step-by-step instructions that cover the most common networking situations and explain how to configure TCP/IP using IPNetRouter. You can find these on our website at <http://www.sustworks.com/site/prod_ipr_started.html>.
If this is your first time setting up IPNetRouter and your requirements are simple (share an Internet connection using the standard built-in ports), we suggest that you try our IPNR Config Application (1). This will step you through IPNetRouter setup and automatically generate a working IPNetRouter configuration file. If the Config App doesn't cover your situation or you want more flexibility and control, then follow the Step-by-step instructions to configure IPNetRouter directly (2).
The "Getting Started" documentation includes an introduction to how the Internet works, a Basic Ethernet tutorial, and links to information on Airport, DHCP, and more. You can also download a PDF version of the web Guide from our website. (Note, if you download the PDF, it may still be helpful to check the website for more info if you run into trouble or need assistance; the web pages are updated more frequently then the PDF documentation.)
There's a help button in the lower left corner of each IPNetRouter window that displays text explaining the controls and features of that window. This text provides the most up-to-date information on that version of IPNetRouter, and is probably the best way to familiarize yourself with more advanced features of the software since you can experiment with the window while you read the description.
Other helpful resources on compatibility and configuration include our Frequently Asked Questions, Troubleshooting, and archive search pages. The URL for these are
See the "Release Notes" document accompanying the Readme for version history information.

9. Registration and Licensing
IPNetRouter is commercial software subject to the terms of the accompanying License Agreement. You may use a demo version of the software during a single trial period of up to 21 days. You must then register the software if you wish to continue using it beyond the trial period.
Notice the trial is designed to expire after 21 days. If the software reports it has expired the first time you launch it, this usually means someone ran a previous version of the program on your computer. Please contact us directly for information on how to reset the trial period.
Once you have downloaded the application, there are 3 basic ways to register:
(1) Register on-line by pressing "WWW Registration Page"
in the About Box for the IPNetRouter Application.
You need to have a web browser running (Netscape Navigator
or MS Explorer) and a valid credit card.
(2) Use the supplied Register application to fill-in a Kagi
registration form. Follow the instructions on the form to
email, fax, or postal mail your registration to Kagi. Most
common forms of payment are acceptable including personal
checks.
(3) For site license registrations, we can fax your company a
proforma invoice. Please contact us directly at
<mailto:info@sustworks.com> .
In each case, a program registration code that unlocks the
demo startup screen and expiration will be sent to you by
email once your payment is received.
The registration code is based on the name you supply in the "Register to"
field of the register application. Please enter your name followed by
your organization name (if any) exactly as you want them to appear.
Although the Register application only provides one line to enter this
information, you can split the text between the name and organization
lines of the IPNetRouter registration screen as long as it contains
exactly the same sequence of characters including any spaces.
IPNetRouter Pricing
Single Gateway Machine $89
Site License $3000
Additional payment details are included below and on our registration web page at
<http://www.sustworks.com/site/reg.html>
Payment Details (Kagi)
Paying for IPNetRouter is fairly simple. Open the Register program that
accompanies IPNetRouter. Enter your name, your email address, and the
number of single user licenses you desire for each program you
wish to purchase (or Site licenses). Save or Copy or Print the data
from the Register program and send the data and payment to Kagi.
Kagi handles my payment processing.
If paying with Credit Card or First Virtual, you can email or fax the data
to Kagi. Their email address is sales@kagi.com and their fax number is
+1 510 652-6589. You can either Copy the data from Register and paste into
the body of an email message or you can Save the data to a file and you can
attach that file to an email message. There is no need to compress the data file,
it's already quite small. If you have a fax modem, just Print the data to the Kagi
fax number.
Payments sent via email are processed within 3 to 4 days. You will receive an email acknowledgement when it is processed. Payments sent via fax take up to 10 days and if you provide a correct Internet email address you will receive an email acknowledgement.
If you are paying with Cash or USD Check you should print the data using the Register application and send it to the address shown on the form, which is:
Kagi
1442-A Walnut Street #392-HQ
Berkeley, California 94709-1405
USA
You can pay with a wide variety of cash from different countries but at present if you pay via check, it must be a check drawn in US Dollars. Kagi cannot accept checks in other currencies, the conversion rate for non-USD checks is around USD15 per check and that is just not practical.
If you have a purchasing department, you can enter all the data into the Register program and then select Invoice as your payment method. Print three copies of the form and send it to your accounts payable people. You might want to highlight the line that mentions that they must include a copy of the form with their payment. Kagi can not invoice your company, you need to act on my behalf and generate the invoice and handle all the paperwork on your end.
Please do not fax or email payment forms that indicate Cash, Check or Invoice as the payment method. As far as we know, there is still no technology to transfer physical objects via fax or email and without the payment, the form cannot be processed. Payments sent via postal mail take time to reach Kagi and then up to10 days for processing. Again, if you include a correct email address, you will hear from Kagi when the form is processed.
The Register application is currently configured to require an email address
since this is the preferred mechanism for distributing registration keys.
If you need to make other arrangements, please contact the author directly
at info@sustworks.com .
