Internet Connection Sharing (ICS) setup : part 1
8. To configure Internet Connection Sharing (ICS), on the first
computer which will become the ICS host (a Windows Vista PC),
activate the Internet connection that is going to be shared. In
this demo, the host computer is going to be connected to a
broadband DSL Internet connection through wireless (Wi-Fi) link. A wireless connection
must be created from the wireless adapter to a
broadband modem/router/access point. Click Connect to a network
in the left pane of Network and Sharing Center or click Connect
to from the Start. In the
"Connect to a network" dialog box, choose the wireless network name (SSID) that refers to
the wireless access point and click Connect. If your host computer
connects using an Ethernet cable or a USB cable to the router, just plug in your cable ends to the
spare Ethernet/USB port on your computer and to the router's
Ethernet/USB port.
You can verify that your network connections (both the direct
Ethernet cable connection and the Internet connection) have been
turned on from Network Connections folder. For easier
identification later, rename each connection with a new name. In
this example, they are renamed to Direct Ethernet Connection and
Home Wireless Internet.

and broadband Internet connection turned on.
If the Internet connection is active, now you can see a
complete representation of the network on Network and Sharing
Center which consists of a simple network map without red cross
(disconnected sign) on the lines and the connections names and
descriptions. Multiple networks refers to two connections from
the host computer (DESKTOP running Windows Vista in this demo),
namely the direct Ethernet connection - referred to as
Unidentified network- and the wireless Internet connection to broadband wireless
router/access point - identified by its SSID. To view a full
network map, click View full map. The map picture shows a link
from a computer to the Internet globe via an Internet
gateway device.
If you have Windows Live OneCare installed and turned on on the
host computer, on the OneCare Firewall Advanced Settings' Network
connections tab, the direct Ethernet connection and the broadband
wireless Internet connection work on Home or Work Zone
which follows the setting in Network and
Sharing Center. Computers on "Home or Work" zone are able to see
each other and access the shared resources (files,
folders, printers, Internet connection).
