In windows xp sp2, the checkbox on the “Advanced" tab of the connection properties is replaced with a "Set" button that you can use to configure general settings, programs, and services. Permissions, settings specified for the connection, log settings, and allowed icmp traffic.






























The new windows firewall dialog contains the following tabs:

On “General” Tab On top, you can choose from the following options:
“Enable (Recommended)”
Select this option to enable Windows Firewall for all network connections selected on the “Advanced” tab.
Windows Firewall will only allow requested and abnormal incoming traffic when enabled. Abnormal traffic can be configured on the "Exceptions" tab.
“About Abnormal Traffic"
Click this option to allow only incoming traffic for the request. This will not allow abnormal incoming traffic. The settings on the "Exceptions" tab will be ignored and all connections will be protected regardless of the settings on the “Advanced" tab.

Select this option to disable the Windows Firewall. This is not recommended, especially for network connections that are directly accessible via the internet.
Note: For all connections and newly created connections to computers running Windows XP SP2, the default setting for Windows Firewall is “Enable (recommended)”. This can affect the communication of programs or services that rely on unsolicited incoming traffic. In such cases, you must identify those programs that are no longer working and add them or their traffic as abnormal traffic. Many programs, such as internet browsers and email clients (such as Outlook Express), do not rely on unsolicited incoming traffic, so they can operate correctly with Windows Firewall enabled.
If you are using Group Policy to configure the Windows Firewall on a computer running Windows XP SP2, the Group Policy settings you configured may not allow local configuration. In such cases, the options on the "General" tab and other tabs may be grayed out and cannot be selected, even local administrators cannot make selections.
Group Policy-based Windows Firewall settings allow you to configure a domain profile (a set of windows firewall settings that will be applied when you connect to a network that contains a domain controller) and a standard profile (a set will be on you) Connect to a Windows Firewall setting that is applied when a network like the internet does not contain a domain controller). These configuration dialogs only show the Windows Firewall settings for the currently applied profile. To view the settings of a profile that is not currently applied, use the netsh firewall show command. To change the settings of a profile that is not currently applied, use the netsh firewall set command.
& ldquo;Exceptions &

On the "Exceptions" tab, you can enable or disable an existing program or service, or maintain a list of programs or services that define unusual traffic. . Abnormal traffic will be rejected when the “Allow Unwanted Traffic" option is selected on the “General" tab.
For windows xp (pre-sp2), you can only define abnormal traffic based on the Transmission Control Protocol (tcp) or User Datagram Protocol (udp) ports. For windows xp sp2, you can define abnormal traffic based on the tcp and udp ports or the file name of the program or service. This configuration flexibility makes configuring anomalous traffic easier when the tcp or udp port of the program or service is unknown or needs to be dynamically determined at the start of the program or service.
There is a set of pre-configured programs and services, including:
File and Print Sharing, Remote Assistant (enabled by default), Remote Desktop, upnp framework, these predefined programs and services are not removable.
If Group Policy allows, you can also create additional anomalous traffic based on the specified program name by clicking "Add Program", and create a tcp or udp based on the specified by clicking “Add Port” Abnormal traffic on the port.
When you click “Add Programs, the "Add Programs" dialog box will pop up, where you can select a program or browse the file name of a program.
When you click “Add Port", the “Add Port” dialog box will pop up where you can configure a tcp or udp port.
One of the features of the new Windows Firewall is the ability to define the range of incoming traffic.
