15、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 tra

16、ffic） 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 Protoc

17、ol （ICMP） messages, Windows Firewall does not drop outgoing traffic.New Features of Windows FirewallIn Windows XP SP2, there are many new features for the Windows Firewall, including the following:Enabled by default for all of the connections of the computerNew global configuration options that appl

18、y to all connectionsNew Windows Firewall component of Control PanelNew operating modeStartup securityIncoming traffic scoping for IPv4Excepted traffic can be specified by program filenameBuilt-in support for IPv6New configuration optionsConfiguration using group policy settingsEnabled by Default for

19、 All of the Connections of the ComputerIn Windows XP with Service Pack 1 （SP1） and Windows XP with no service packs installed, ICF is disabled by default for all connections, unless enabled for an Internet connection by the Network Setup Wizard or Internet Connection Wizard. You can manually enable

20、ICF through a single checkbox on the Advanced tab of the properties of a connection, from which you can also configure the set of excepted traffic by specifying Transmission Control Protocol （TCP） or User Datagram Protocol （UDP） ports.Windows Firewall in Windows XP SP2 is globally enabled by default

21、. This means that, by default, all the connections of a computer running Windows XP with SP2 have Windows Firewall enabled, including LAN （wired and wireless）, dial-up, and virtual private network （VPN） connections. New connections also have Windows Firewall enabled by default.Although this provides

22、 more protection for Windows XP-based computers, this default behavior can have consequences for the information technology （IT） department of an organization network with regards to application compatibility and the ability to manage the computers on the network. For more information, see Windows X

23、P SP2 and the Impact to Enterprise Networks in this article. New Global Configuration Options that Apply to All ConnectionsWindows Firewall in Windows XP SP2 allows you to configure settings that apply to all the connections of the computer （global configuration）. In Windows XP with SP1 and Windows

24、XP with no service packs installed, ICF settings are configured per connection, which means that if you want to enable ICF on multiple connections and configure excepted traffic, you must configure each connection separately. When you change a global Windows Firewall setting, the change is applied t

25、o all the connections on which Windows Firewall is enabled.Windows Firewall in Windows XP SP2 also allows per-connection configuration. Connection-specific configuration overrides global configuration.New Windows Firewall Component of Control PanelThe settings for ICF in Windows XP with SP1 and Wind
