Version 1.5 WINDOWS 95/98/ME/NT/2000/XP 28. March, 2001
-----------------------------------------------------------------------------
NAT32X is a versatile Software Router which allows all computers on one or
more private LANs to simultaneously share several Internet connections.
With appropriate configuration, NAT32X will bind to the following devices:
Windows WAN devices: Modems, ISDN, ADSL, PPPoE, Microsoft VPN
Windows LAN devices: Ethernet, Token Ring (but not emulated TR)
Hybrid Devices: One-way cable modems, Satellite devices (DirecPC)
NAT32X suports interface-specific address translation and port mapping.
Multiple default routes are supported, allowing specific traffic from a
desired network or host to use a specific default route.
NAT32X fully supports the Windows DUN/RAS Server, allowing dial-in access on
up to 8 Serial Ports to a machine which connects to the Internet via one or
more Network Interface with registered IP addresses.
Administrators can remotely configure and interrogate NAT32X using a Java-
enabled WEB Browser. A NAT32 password must be specified and Internet access
to the NAT32X HTTP server is blocked per default.
NAT32X is an IP Router, NOT a Proxy Server. Time-consuming reconfiguration
of network applications is not required. All applications on your private
LAN have address-mapped UDP, TCP and ICMP access to the Internet.
Installation
------------
The NAT32X archive can be unzipped into any desired directory, the example
below assumes the directory C:\NAT32.
You should then run the setup program setup.exe. This program makes NO major
modifications to your system. In particular, no Windows DLLs or Drivers are
overwritten or modified, and your networking configuration is not altered
in any way. Only minor registry modifications are made. Only one file is
copied: nat32.inf to your Windows INF directory.
Before Running NAT32X:
----------------------
This version *requires* Internet Explorer 4 (or later). Even if you are a
Netscape or Opera user, you must install IE, even if you uninstall it again
afterwards. The IE uninstall procedure leaves all the needed DLL's on your
system.
WINDOWS 95 users should install the Microsoft DUN 1.3 (or later) upgrade
before running NAT32X. This upgrade is an absolute must (even for Cable
Modem users) because it contains the latest VIP.386 and TCP/IP upgrades,
as well as vastly improved Dial-Up Networking support. The upgrade is
available for free download from www.microsoft.com.
IMPORTANT
---------
You must turn off IP Header Compression for all DUN Connections you
plan to use with NAT32 (95/98/NT4 platforms only). If you ran setup,
this will have been done for you, but any connnections you add later
will need to have IP Header Compression turned off manually.
Installing NDIS3PKT
-------------------
NAT32X uses a special version of Dan Lanciani's NDIS3PKT driver. DO NOT
ATTEMPT to run NAT32X with any version of NDIS3PKT other than the one
contained in this distribution.
1. Start the Control Panel Network Applet and click Add then Protocol.
Under Windows 2000 and XP, open Control Panel, Network and Dial-up
Connections, and then right-click any Local Area Connection.
Then click Install and select Protocol, Add.
2. Click the "Have Disk" button and specify the directory into which you
unzipped NAT32X as the source directory.
3. Click OK.
4. REBOOT WINDOWS, even if a reboot is not requested. Note that the NDIS3PKT
driver can only bind to adapters which Windows enables at boot time.
If you have disabled an adapter, reenable it and then reboot Windows so
that NDIS3PKT can bind to it.
Running NAT32X
--------------
The first time NAT32X is run, it examines the existing network configuration
and generates several configuration files in the directory from which it was
started.
IMPORTANT
---------
For NAT32X autoconfiguration to work correctly, you MUST have at
least one private LAN adapter which has been assigned a FIXED IP
address. That address should be private, but it needn't be.
A Dialog Box will be presented listing all Network Interfaces available on
your system, and you should then select the Interfaces you would like NAT32X
to use. One of those Interfaces (the one which connects to the Internet)
should be designated as the Primary Shared Interface, all others must have
the Primary and Shared checkboxes unchecked.
A Shortcut will be added to your Desktop, and you should use that shortcut
whenever you subsequently wish to run NAT32X with the selected interfaces.
IMPORTANT
---------
NAT32X can be run as a Service, but you MUST NOT start it as
a service until it has been correctly configured and you have
familiarized yourself with its operation.
NAT32X is documented in the Windows Help File: nat32x.hlp.
************************ HOW TO UNINSTALL NAT32X ****************************
* *
* Click Start/Programs/NAT32/Uninstall *
* *
* Uninstall leaves a few configuration files in your NAT32 directory, so *
* you should subsequently drag the NAT32 directory to the Reycle Bin. *
* *
* To uninstall NDIS3PKT, use Control Panel Network to remove the driver. *
* *
*****************************************************************************
************************** HOW TO UPDATE NAT32X *****************************
* *
* 1. Stop the running NAT32X Application or Service *
* 2. Copy your startup file to "starup.bak" *
* 3. Unzip the new NAT32X.ZIP file in your NAT32X directory, allowing it to *
* overwrite all files. *
* 4. Copy "startup.bak" to "startup" *
* 5. Restart the new NAT32X application or Service. *
* *
* NOTE: if a new NDIS3PKT driver has been published, please uninstall the * *
* existing driver, reboot Windows and then install the new driver. *
* *
*****************************************************************************
NAT32X is SHAREWARE and will run for 60 minutes to allow you to evaluate its
features. NDIS3PKT has been modified to run with NAT32X only.
When the Evaluation Period has expired, the NDIS3PKT driver will be stopped,
and can only be restarted by rebooting Windows.
