Non Microsoft Internet Connection Sharing

by Johannes Helmig [Published on 11 Aug. 2001 / Last Updated on 11 Aug. 2001]

On some countries, more and more families have 2 (or even 3) PC's:
- one for the parents, used for business work
- one for the children, to play (and to do some school-work......)

Both like to connect to the Internet. But in most houses, there is only one phone-line.

With Windows 98 Second Edition ,Windows ME and Windows 2000, Microsoft has included
this functionality as : Internet Connection Sharing ( ICS ) :


If your Microsoft Windows version does not include this ICS feature (like: Windows 95,
Windows98 First Edition or Windows NT4), then you can use a Non-Microsoft package
to share your Internet connection.
Also, when using an ADSL-line or cable-modem to connect to the Internet, the ICS of
Windows98SE/ME may not work properly, requiring you to use a Non-Microsoft package
to share your ADSL or Cable-Modem Internet connection.


There are several such packages available , I will use here as example
( installed on Win98 and NT4 ) :

WinRoute Lite
from Kerio
(previously offered by TinySoftware )
The installation is very simple: just run the WinRouteLite.exe.
Note: ONLY install WinRouteLite on the system, which has
the connection to the Internet ( ICS Host ).
Do NOT install WinRouteLite on the other systems (ICS Clients)
After the system restart, WinRouteLite is running and showing
an icon in your taskbar.
Make a right-click on the WinRouteLite icon to display
the control-menu:
you will need to make some "Administration" :
tab: General

WinRouteLite is NOT Free !
:
You can evaluate it for
30 days, but if you like then
to continue to use the
program, you will need
to purchase it and to
enter the License Nr.
tab: Settings

Select your method of
connection to the Internet:
- via Modem or
- via cable, DSL, .....
select the Connection and
enter the Username and
password required to
establish this connection.





Verify the Advanced Settings.
tab: DHCP:
for home usage, it is most
easy to enable DHCP for
automatic configuration
of the TCP/IP protocol

of the ICS Clients.

Note: if you are using such
a program on an office network,
which has already a DHCP
server
, then deactivate this
DHCP-server.
tab: DNS Proxy

for home use, use the
DNS defaults.
tab: Port Mapping

for home use, there should
be no need to map any port.
If you need to do this,
download the User Guide
for WindRouteLite and
follow the instructions in there.
tab: Security

There are a lot of "bad guys"
on the Internet snooping
around and trying to "break in"
to other people's systems,
some just look around, Others
delete data, so you need to
protect your system.
WinRouteLite includes
a "Personal Fierewall", which
is active when you do NOT
Open all ports on the PC.

So: NO Checkmark here !

Whatever product you decide to install : make sure that it either include a Firewall or
that you add an additional
Personal Firewall !
And then
TEST that your protection is working: run the test at www.grc.com :


Usage of WinRoute Lite on the Host:

To make from the ICS Host
(where WinRouteLite is
installed) a connection to
the Internet, call up the
WinRouteLite Administration
and use in the section
"Dial-Up Status" the
button "Dial"
The button "Dial" changes to
"Hangup", the systems
uses the configured connection
to connect to the Internet.
Once connected, it will
show the connection time.

To terminate later the
connection to the Internet,
call up again the WinRouteLite
Administration and use
"Hangup"
WinRouteLite Administration
shows you the
"Active Connections":
which of your other systems
on the network is using the
connection to the Internet

Using the Internet Connection on the Client systems

First: do NOT install WinRouteLite on any of the client systems !

Configuration of Windows 9x (95/98/ME ):

In the Network configuration, select
for the TCP/IP protocol the "Properties"
and define on the tab: IP-address:
- Obtain an IP address automatically

This requires, that WinRouteLite is
configured to act as DHCP-server
or that
there is another DHCP-server on the network
assigning the proper values.
( the Auto-IP-configuration of Windows98/ME
and Windows 2000 will NOT assign all
required TCP/IP parameters ! )





If you changed any value, you will need
to restart/reboot your system.
Verify the configuration of TCP/IP
(to make sure it worked properly) by
using from the Start-menu/Run the
command: WINIPCFG :
Display "More Info >>"
The IP-address assigned has to be in the range
configured in the WinRouteLite DHCP settings
The system running WinRouteLite is
defined as "Default Gateway" and as
"DNS server".

If you selected NOT to configure your
ICS Clients for automatic TCP/IP
configuration, then you can configure
manually all the required information:
- IP-address
- subnet mask
- Default Gateway
- DNS-server
In the Properties of the "Internet Explorer"
(or use in the Control-panel the
Internet Options ):

Tab: Connections:

If you have Dial-up connections on this
system, deactivate them by selecting
"Never dial a connection"
(which is the action performed, when you
run the "Internet Connection Wizard"
and select to work via LAN)


If you start up now any Internet related program (like an Internet Browser or FTP-client),
WinRouteLite on the ICS Host will make the connection to the Internet. You can check this
also by making a PING:


When starting up an Internet Browser and WinRouteLite has to make the connection,
it may take more time to connect than the Browser is waiting, which then reports:

just wait a few seconds and click on "Refresh" to try again.


WinRouteLite and Windows NT4:

The operation on a Windows NT4 system is identical to Windows9x, except:

when connecting to the Internet,
there will be NO RAS icon/
Dialup networking Monitor

in your taskbar.
You are controlling
everything ONLY via
WinRouteLite.
NT4 as ICS Client can
receive the TCP/IP
configuration from a
ICS Host running
WinRouteLite.







There is no WINIPCFG
command on Windows NT4,
use IPCONFIG to check
the TCP/IP values configured
by the DHCP-server.
