HOW TO use NAT32 with Windows 98 Direct cable Connection (DCC):
Windows 98 allows two machines to be connected via serial or parallel
ports linked with an appropriate cross-over cable. This is sometimes useful
if you have an older model laptop for which an Ethernet Adapter is either
too expensive or no longer available. DCC supports full TCP/IP networking
and Windows File and printer Sharing. Quite substantial transfer rates
can be achieved, depending on your hardware.
To use this feature, you must do three things:
Run DCC on the NAT32 machine
-
Simply run the program directcc.exe
-
If that program doesn't exist on your machine, then you haven't installed
Windows Direct Cable Connection and you should open Control Panel Add/Remove
Programs and then click Windows Setup. Select Communications and then check
both Dial-Up Networking and Direct Cable Connection.
-
If you are running Windows 98 SE, then you can create a shortcut on your
Desktop containing the following command line:
c:\Windows\directcc.exe host
-
You can place a link to that shortcut in the Windows Startup Folder if
you need to start DCC in host mode at boot time.
Run DCC on the Laptop
-
Follow the same procedure as above, only this time, run DCC in guest
mode.
Configure NAT32
-
First download the latest version of NAT32: Download
-
Unzip the file into your NAT32 directory and install
the NDIS3PKT driver as described here.
-
Start your DUN Connection to your ISP.
-
Start the DCC Host on the NAT32 machine and the DCC
Guest on the Laptop.
-
If the two machines don't link up, correct the problem
before continuing.
-
Run NAT32 as:
This special version of NAT32 will configure IFN2 to "hook into" the Windows
Dial-Up Networking Adapter (your DCC connection) and it will configure
IFN3 to "hook into" the Windows Dial-Up Networking Adapter #2 (your connection
to your ISP). The NAT32 Interface Configuration Dialog Boxes should look
exactly like this:
Of course, for your particular ISP, the IP address 137.92.142.35 will
be different, but in all other respects the exact configuration shown above
must be used.
Windows on your NAT32 machine will automatically use the IP address
192.168.55.1. If it doesn't, check that you have Microsoft TCP/IP installed
on both machines and also check that the Dial-Up Networking Adapter has
Point
To Point IP enabled.
Note that none of this will work unless you have DUN 1.3 (or later)
installed on.both machines. I have tested under Windows 98 SE on the NAT32
machine and either Windows 95 (with DUN 1.3) or Windows 98 (first edition)
on the Laptop.
NAT32 on the host machine will use the IP address 192.168.55.100.
To all intents and purposes, the DCC connection is viewed as a TCP/IP
connection by your networking applications, and you should be sure that
TCP/IP on the Laptop is configured as described here.
Troubleshooting
Windows DCC uses a rather fragile program called rnaapp.exe which
sometimes has various difficulties. If you cannot get the two machines
to connect, please try the following:
-
Open the Control Panel System applet.
-
Select the Device Manager.
-
Under Modems you will see all the "Modems" which your machine knows
about. This list includes LPT ports too.
-
Note that the "Modems" which DCC uses never appear in the Control
Panel Modems applet.
-
Check the Properties of the "Modem" being used (even if it is actually
an LPT port), and ensure that the settings are the same on both machines.
-
Sometimes, unplugging both machines and then reconnecting them works wonders!
-
If none of this helps, reboot both machines.
-
If it still doesn't work, consult a local Windows expert or search for
one of the numerous pages on the Internet which describe how to use DCC.
