The Windows Internet Connection Firewall (ICF) exists on many Windows XP computers. However, when running, ICF can interfere with Internet connection sharing through a home network router. If such a conflict arises on your Windows XP computer, you might find that it cannot connect to the Internet through the router. Follow these instructions to disable the Windows firewall. You can safely disable the firewall as a home network router provides equivalent (and often better) security.
