How to Share a Cable MODEM
with Windows 98 Second Edition
Last updated: 8/16/00
 INTRODUCTION. Success! I
just installed Windows 98 Second Edition Internet Sharing Software (ICS)
on our Mom 'n Pop Local Area Network and it works well with our ISP supplied
external cable MODEM, on a one-way cable system. At last, Claudia can
(if I make it coexist with our NT and intranet Web servers) share the Internet
connection and (ah!) read my mail. Here's how...
Windows 98 Second Edition (Win 98 SE) includes Microsoft's
Internet Connection Sharing (ICS) adapter and protocol. ICS is one
way to connect your Windows Local Area Network (LAN) to the Internet and
share an Internet connection with other users of the LAN. A Win 98
SE computer, running ICS, provides a LAN to Wide Area Network (WAN) gateway
to the Internet for other computers on the LAN. ICS uses Network Address
Translation (NAT) to map LAN Internet
Protocol (IP) addresses to Internet IP addresses and vice versa. It
has a simplified Dynamic
Host Configuration Protocol (DHCP) and a Domain Name Server (DNS)
proxy which together manage IP addresses and Internet name resolution requests
(translates names of computers on the Internet to IP addresses) for client
computers on the LAN, etc. etc.
The other computers can be running Windows 95/98/98 SE
and Internet Explorer 3.x and higher or Netscape 3.x and higher. With
this gateway, all of the users of the computers on the network, including
the one serving as the gateway, will be able to browse the Internet and download
files simultaneously through a single Internet connection. This article
will show you how to interface a Windows 95/98 workgroup network to the Internet
with a Win 98 SE PC, ICS, and an external cable MODEM (CM).
