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.

ICS Microsoft Internet Connection Sharing

Microsoft ICS allows two or more networked computers to share a single Internet connection. ICS makes use of DHCP. ICS routes TCP/IP packets from a small LAN to the Internet. ICS maps individual IP addresses of local computers to unused port numbers in the TCP/IP stack. ICS has very annoying limitations that were purposely imposed by the Microsoft developers. The original Win98SE ICS could actually do more than the version now distributed with XP.

Limitations

  • there is no way to review DHCP leases using ICS.
  • no provisions for bandwidth limiting
  • server will always have the IP address 192.168.0.1 so the WAN may not use that subnet
  • subnet may not be modified even if the client is static
