Internet Connection Sharing on Windows XP
From Free Knowledge Base- The DUCK Project: information for everyone
Microsoft Windows 98 Second Edition came with ICS "Internet Connection Sharing" as part of the distribution. Previously, individuals wishing to share Internet from one Windows PC to another, with the previous hosting the WAN connection, third party software such as Wingate was necessary. ICS changed all that, or did it?
Microsoft Internet Connection Sharing, or ICS, has been watered down and like so many other lame Microsoft products, Microsoft has intentionally handicapped ICS so that with all of its limitations, it leaves the end user needing more, opening the door to third party software once again.
