You have just set up a new Windows XP Professional computer at home. The computer is always connected to the internet via an ADSL modem. The computer is configured to have a static IP address assigned by your Internet Service Provider. You enable the Internet connection Firewall on the ADSL connection. You use the Ping command on your office computer to try to connect to your home computer. However, you receive the following error message: “Request timed out.”
The ping command sends a series of ICMP echo requests to the specified computer. However, the ICMP echo requests are being dropped by the firewall and are therefore not reaching the specified computer. We need to configure the firewall to allow the ICMP echo requests so that they can pass to the specified computer.
