1Click Start, point to All Programs, point to Accessories, point to Communications, and then click Network Setup Wizard.





2.Click Next until you see the Select a connection method screen.





3.Click This computer connects directly to the Internet, and complete the wizard to install ICS.





This method has several advantages in that the wizard automatically detects the connection to the Internet, configures Internet Connection Firewall (ICF), bridges multiple network adapters connected to your home network and creates a log of information about the configuration named nsw.log in the Windows folder.





Turning on ICS manually is almost as easy as using the wizard except that you need to create the bridge for multiple network cards before enabling ICS. (See an earlier column, Building Network Bridges for more information on how to use the bridging capability in Windows XP.) Then take these steps:





1.In Control Panel, click Network and Internet Connections and then click Network Connections.





2.Click the local area network (LAN) connection or the dial-up networking connection that you want to share (that is, the one that connects to the Internet), and then, under Network Tasks, click Change settings of this connection.





3.Disable Client for Microsoft Networks and File and Print Sharing for Microsoft Networks by clearing the check boxes shown in Figure 1. This step is extremely important. Never leave these items enabled for any network card that is directly connected to the Internet (see sitting duck, above).





4.Click the Advanced tab, and select the Allow other network users to connect through this computer's Internet connection check box.





5.You can enable or disable the allowing of other users to control the connection鈥攗sers don't need to be able to control the connection to use it.





6.Under Internet Connection Firewall, select the Protect my computer and network by limiting or preventing access to this computer from the Internet check box for this network card, unless you have another firewall between the computer and the Internet. This is very important.





7Click OK, and Internet Connection Sharing will be enabled.How can i Split my internet into 4.?
Use a router that supports QoS or Quality of Service. Many SOHO routers now support that technology. That will allow you to manage the available bandwidth by several means such as logical port, physical port, IP address, MAC address or protocol.





If you want to set absolute traffic limits, such as so many megs of use per day, you'll need some type of monitoring software on each machine such as NetNanny or something similar.
