SUMMARY
Microsoft Windows XP provides Internet security in the form of a firewall,
known as the Internet Connection Firewall (ICF). This feature is designed
for home and small business use and provides protection for computers
directly connected to the Internet. This feature is available for local area
network (LAN) or dial-up connections. It also prevents scanning of ports and
resources (file and printer shares) from external sources. This article
discusses how to enable the Internet Connection Firewall feature to provide
Internet security for your computer. This article also discussed how to
disable the Internet Connection Firewall feature, which may help in
troubleshooting some applications that do not function as expected behind a
firewall.

Enable Internet Connection Firewall
The Internet Connection Firewall is useful when you want to protect a
dial-up connection when dialing directly into an Internet service provider
(ISP), or to protect a LAN connection that is connected to an asymmetric
digital subscriber line (ADSL) or cable modem. You can also enable the
Internet Connection Firewall feature on the Internet connection of an ICS
host computer to provide protection to the ICS host computer.
To enable Internet Connection Firewall feature using the Network Setup
Wizard:
1.. Run the Network Setup Wizard. To access this wizard, point to Control
Panel, double-click Network and Internet Connections, and then click Setup
or change your home or small office network.
2.. The Internet Connection Firewall is enabled when you choose a
configuration in the wizard that indicates that your computer is connected
directly to the Internet.
To configure Internet Connection Firewall manually for a connection:
1.. In Control Panel, double-click Networking and Internet Connections,
and then click Network Connections.
2.. Right-click the connection on which you would like to enable ICF, and
then click Properties.
3.. On the Advanced tab, click the box to select the option to Protect my
computer or network.
4.. If you want to enable the use of some applications and services
through the firewall, you need to enable them by clicking the Settings
button, and then selecting the programs, protocols, and services to be
enabled for the ICF configuration.
