SUMMARY
With the Internet Connection
Sharing (ICS) feature of network and dial-up connections, you can use
Windows to connect your home network or small office network to the
Internet. For example, you may have a home network that connects to the
Internet by using a dial-up connection. By enabling ICS on the computer that
uses the dial-up connection, you are providing network address translation,
addressing, and name resolution services for all computers on your home
network.
MORE
INFORMATION
To enable ICS on a network
connection:
1.
In Control Panel ,
double-click Network and Dial-Up Connections .
2.
Right-click the
connection you want to share, and then click Properties .
3.
Click the Sharing
tab, and then click to select the Enable Internet Connection Sharing for
this connection check box.
4.
If the connection you
are sharing is a Dial-up connection and you want the connection to dial
automatically when another computer on your home network attempts to use
external resources, click to select the Enable on-demand dialing check box.
NOTE : To
enable ICS in Windows, you must have administrative rights.

IMPORTANT : You should not use this feature on a computer running DNS server
or DHCP server or a Windows domain controller. When you enable ICS, the
network adapter connected to the home or small office network is given a new
static IP address configuration. Existing TCP/IP connections on the CS
computer are lost and need to be re-established.

Configuration and Usage
Issues
The ICS feature
is intended for use in a small office or home office in which the network
configuration and the Internet connection are managed by the Windows-based
computer on which the shared connection resides. It is assumed that on its
network, this computer is the only Internet connection, is the only
gateway to the Internet, and that it sets up all internal network
addresses.

You cannot modify the default network configuration after enabling ICS.
This includes items such as the range of private IP addresses that are
handed out (DHCP allocator), enabling or disabling DNS, configuring a
range of public IP addresses, or configuring inbound mappings.
If your home office users need to gain access to a corporate network that
is connected to the Internet by a tunnel server from a ICS network, they
need to create a virtual private network (VPN) connection to tunnel from
the computer on the ICS network to the corporate tunnel server on the
Internet. The VPN connection is authenticated and secure, and creating the
tunneled connection allocates proper IP addresses, DNS server addresses,
and WINS server addresses for the corporate network.

You may need to configure programs and services to work properly across
the Internet. For example, if users on your home network want to play a
game with other users on the Internet, the game must be configured on the
connection in which ICS is enabled. Services that you provide must be
configured so that Internet users can gain access to them. For example, if
you are hosting a Web server on your home network and you want Internet
users to be able to connect to it, you must configure the Web Server
service.
