This article examines how to configure Windows Firewall using the Netsh command-line utility.
Windows XP Service Pack 2 (SP2) includes the Windows Firewall, a replacement for the feature previously known as the Internet Connection Firewall (ICF). Windows Firewall is a stateful host firewall that drops all unsolicited incoming traffic that does not correspond to either traffic sent in response to a request of the computer (solicited traffic) or unsolicited traffic that has been specified as allowed (excepted traffic). This behavior of Windows Firewall provides a level of protection from malicious users and programs that use unsolicited incoming traffic to attack computers. With the exception of some Internet Control Message Protocol (ICMP) messages, Windows Firewall does not drop outgoing traffic. Windows Firewall is also included with Windows Server 2003 Service Pack 1 (SP1).
Now we configure Windows Firewall step-by-step
Step 1. Windows Firewall: General
The General tab with its default settings is shown in the following figure.
From the General tab, you can select the following:

Step 2. Windows Firewall: Exceptions
The following figure shows the Exceptions tab with its settings.
From the Exceptions tab, you can enable or disable an existing program (an application or service) or port or maintain the list of programs and ports that define excepted traffic. The excepted traffic is not allowed when the Don't allow exceptions option is selected on the General tab.

If the application using the Windows Firewall APIs does not specify an exception name, the exception is not displayed in the exceptions list on the Exceptions tab of the Windows Firewall.
When an application that does not use the Windows Firewall API runs and attempts to listen on TCP or UDP ports, Windows Firewall prompts a local administrator with a Windows Security Alert dialog box. The following figure shows an example.

If you clear all of the check boxes in the Network Connection Settings, then Windows Firewall is not protecting your computer, regardless of whether you have selected On (recommended) on the General tab. The settings in Network Connection Settings are ignored if you have selected Don’t allow exceptions on the General tab, in which case all interfaces are protected.
When you click Settings, the Advanced Settings dialog box is displayed, as shown in the following figure.

From the ICMP dialog box, you can enable and disable the types of incoming ICMP messages that Windows Firewall allows for all the connections selected on the Advanced tab. ICMP messages are used for diagnostics, reporting error conditions, and configuration. By default, no ICMP messages in the list are allowed.
A common step in troubleshooting connectivity problems is to use the Ping tool to ping the address of the computer to which you are trying to connect. When you ping, you send an ICMP Echo message and get an ICMP Echo Reply message in response. By default, Windows Firewall does not allow incoming ICMP Echo messages and therefore the computer cannot send an ICMP Echo Reply in response. To configure Windows Firewall to allow the incoming ICMP Echo message, you must enable the Allow incoming echo request setting. Set Windows Firewall ICMP Settings using command line

OS X v10.5.1 and later include an application firewall you can use to control connections on a per-application basis (rather than a per-port basis). This makes it easier to gain the benefits of firewall protection, and helps prevent undesirable apps from taking control of network ports open for legitimate apps.
Configuring the application firewall in OS X v10.6 and later
Use these steps to enable the application firewall:
Configuring the Application Firewall in Mac OS X v10.5
Make sure you have updated to Mac OS X v10.5.1 or later. Then, use these steps to enable the application firewall:
Advanced settingsBlock all incoming connections
Selecting the option to 'Block all incoming connections' prevents all sharing services, such as File Sharing and Screen Sharing from receiving incoming connections. The system services that are still allowed to receive incoming connections are:
To use sharing services, make sure 'Block all incoming connections' is deselected.
Allowing specific applicationsAdd An App As An Exception To Firewall Mac Settings
To allow a specific app to receive incoming connections, add it using Firewall Options:
You can also remove any apps listed here that you no longer want to allow by clicking the Remove App (-) button.
Automatically allow signed software to receive incoming connections
Applications that are signed by a valid certificate authority are automatically added to the list of allowed apps, rather than prompting the user to authorize them. Apps included in OS X are signed by Apple and are allowed to receive incoming connections when this setting is enabled. For example, since iTunes is already signed by Apple, it is automatically allowed to receive incoming connections through the firewall.
If you run an unsigned app that is not listed in the firewall list, a dialog appears with options to Allow or Deny connections for the app. If you choose Allow, OS X signs the application and automatically adds it to the firewall list. If you choose Deny, OS X adds it to the list but denies incoming connections intended for this app.
Add An App As An Exception To Firewall Mac Address
If you want to deny a digitally signed application, you should first add it to the list and then explicitly deny it.
Some apps check their own integrity when they are opened without using code signing. If the firewall recognizes such an app it doesn't sign it. Instead, it the 'Allow or Deny' dialog appears every time the app is opened. This can be avoided by upgrading to a version of the app that is signed by its developer.
Enable stealth mode
Enabling stealth mode prevents the computer from responding to probing requests. The computer still answers incoming requests for authorized apps. Unexpected requests, such as ICMP (ping) are ignored.
Firewall limitations
The application firewall is designed to work with Internet protocols most commonly used by applications – TCP and UDP. Firewall settings do not affect AppleTalk connections. The firewall may be set to block incoming ICMP 'pings' by enabling Stealth Mode in Advanced Settings. Earlier ipfw technology is still accessible from the command line (in Terminal) and the application firewall does not overrule any rules set using ipfw. If ipfw blocks an incoming packet, the application firewall does not process it.
