Windows XP Firewall

The WindowsXP firewall does provide some functionality, and can be quite effective, though it only offers basic management functions.

To configure the WindowsXP Internet Connection Firewall (this process will require administrator privileges on the machine), follow these steps:
- Start
- Control Panel 
- Network Connections 
- right click on the connection that connects you to the Internet, select Properties.
- Advanced Tab
- Settings

You will need to create one entry for TCP incoming connections.
- Click on Add 
- Under description of service, enter ANtsTCP
- Under Name or IP address of machine, enter 127.0.0.1
- Under Internal port, enter the TCP port (443 is the default)
- Under External port, enter the TCP port (443 is the default)
- Ensure the TCP radio button is selected
- Click OK
