Buy Description of the Windows XP Internet Connection Firewall (Q320855)Internet Connection Firewall is software that you can use to set restrictions on the information that is communicated between your home or small office network and the Internet.If your network uses Internet Connection Sharing (ICS) to provide Internet access to multiple computers, it is a good idea to turn on Internet Connection Firewall on the shared Internet connection. However, you can turn on Internet Connection Sharing and Internet Connection Firewall separately. It is a good idea to turn on Internet Connection Firewall on the Internet connection on any Windows XP-based computer that is connected directly to the Internet. Internet Connection Firewall can also protect a single computer that is connected to the Internet. If you have a single computer that is connected to the Internet with a cable modem, a DSL modem, or a dial-up modem, Internet Connection Firewall protects your Internet connection. Do not turn on Internet Connection Firewall for virtual private network (VPN) connections because Internet Connection Firewall interferes with file sharing and other VPN functions. Internet Connection Firewall is a "stateful" firewall. A stateful firewall is one that monitors all aspects of the communications that cross its path and inspects the source and destination address of each message that the firewall handles. To prevent unsolicited traffic from the public side of the connection from entering the private side, Internet Connection Firewall keeps a table of all of the communications that have originated from the computer that is running Internet Connection Firewall. For a single computer, Internet Connection Firewall tracks traffic that originates from the computer. If you use Internet Connection Firewall in conjunction with Internet Connection Sharing, Internet Connection Firewall tracks all of the traffic that originates from the computer that is running Internet Connection Firewall and Internet Connection Sharing, and tracks all of the traffic that originates from private network computers. Internet Connection Firewall compares all inbound traffic from the Internet to the entries in the table. Inbound Internet traffic is permitted to reach the computers in your network only if there is a matching entry in the table that shows that the communication exchange began in your computer or private network. It is not a good idea to turn on Internet Connection Firewall on any connection that does not directly connect to the Internet. IF you turn on Internet Connection Firewall for the network adapter of a client computer that is running Internet Connection Sharing, Internet Connection Firewall interferes with some communications between that computer and all other computers on the network. For a similar reason, you cannot use the Network Setup Wizard to turn on Internet Connection Firewall on the Internet Connection Sharing host private connection. This is the connection that connects the Internet Connection Sharing host computer with the Internet Connection Sharing client computers. Turning on a firewall in this location would completely prohibit network communications. You can use the Internet Connection Firewall security logging feature to create a security log of firewall activity. Internet Connection Firewall can log both traffic that is permitted and traffic that is rejected. For example, incoming echo requests from the Internet are not permitted by Internet Connection Firewall by default. If the Internet Control Message Protocol (ICMP) Allow incoming echo request setting is not turned on, the inbound request does not succeed, and a log entry that notes the unsuccessful inbound attempt is generated.

The Internet Connection Firewall Can Prevent Browsing and File Sharing (Q298804)When you enable the Internet Connection Firewall (ICF) feature, and then attempt to browse the Internet by means of My Network Places , you are unsucessful. Also, if you use the net view \\ computername command, you can receive the following error message:System error 6118 has occurred. The list of servers for this workgroup is not currently available. This behavior can occur because the ICF closes, by default, the ports for file sharing. The Master Browser attempts to reconnect to the client computer to send the Browse list, but the firewall prevents this reconnection attempt. Click here for the article. HOW TO: Enable or Disable Internet Connection Firewall in Windows XP (Q283673)Microsoft Windows XP provides Internet security in the form of a firewall, known as the Internet Connection Firewall (ICF). This feature is designed for home and small business use and provides protection for computers directly connected to the Internet. This feature is available for local area network (LAN) or dial-up connections. It also prevents scanning of ports and resources (file and printer shares) from external sources. This article discusses how to enable the Internet Connection Firewall feature to provide Internet security for your computer. This article also discussed how to disable the Internet Connection Firewall feature, which may help in troubleshooting some applications that do not function as expected behind a firewall.The Internet Connection Firewall is useful when you want to protect a dial-up connection when dialing directly into an Internet service provider (ISP), or to protect a LAN connection that is connected to an asymmetric digital subscriber line (ADSL) or cable modem. You can also enable the Internet Connection Firewall feature on the Internet connection of an ICS host computer to provide protection to the ICS host computer. Click here for the article. Internet Connection Firewall Does Not Block Internet Protocol Version 6 Traffic (Q306203)With Microsoft Internet Protocol version 6 installed and Internet Connection Firewall enabled, Internet Protocol version 4 traffic is filtered by the firewall but Internet Protocol version 6 traffic is not blocked.Internet Connection Firewall is Internet Protocol version 4 only, so it does not block Internet Protocol version 6 or other protocols. This behavior is by design. Click here for the article.

How to Manually Open Ports in Internet Connection Firewall in Windows XP (Q308127)This article contains the steps to manually open ports in Internet Connection Firewall (ICF) in Windows XP.Programs may potentially require ports to be manually opened so that they function properly when ICF is in use either on the local computer or on the gateway computer.

Service Redirection Does Not Apply to Internet Connection Firewall (Q297942)In Windows XP, the Internet Connection Firewall (ICF) and Internet Connection Sharing (ICS) features share a common interface for configuring services to which Internet users can gain access. With ICS, you can map services to hosts on the internal network, but ICF does not provide this functionality. ICF uses the service information to determine which services to allow through the firewall, but disregards the information that specifies which host should receive traffic for the given service. Therefore, if only ICF is enabled, traffic is allowed for the specified service to pass through the firewall and make a connection to the external interface. If the specified service is not listening on the external interface of the Windows XP ICF host, the connection does not work. If you are trying to redirect a service to an internal host, you must enable ICS.Click here for the article.
