What is the difference between the ICS [Internate Connection Sharing] and ICF [Internate Connection Firewall]?

Please guide me in this regard.

ICF stands for "Internet Connection Firewall" which is ICF is a Windows XP feature that protects computers connected to the Internet from unauthorized access.When ICF is enabled, Windows keeps a log of incoming requests from other systems on the Internet....

ICS stands for Internet Connection Sharing Capabilities....
Multiple users can gain access to the Internet through a single connection by using Dial-Up Networking and local networking.
Connected devices receive transparent network configuration by using Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) to resolve Internet names.

ICS means a computer share its internet access with other computers on a local network. It requires two network connection on for the internet and another for the LAN. ICF prevents other internet users from accessing your network.

ICS stands for "Internet Connection Sharing" and ICF stands for "Internet Connection Firewall."

Internet Connection Sharing is where two or more computers share the same Internet connection. An Internet Connection Firewall is a Windows XP-specific feature that monitors and limits incoming Internet traffic. ICS and ICF can be enabled independently, which means you can have ICF turned on and ICS off, or vice versa.

If you are sharing an Internet connection, ICF should only be enabled for the computer or router that is directly connected to your Internet connection. It should not be configured for each computer on the network. If you only have one computer connected to the Internet, you can enable ICF directly on that machine and ICS is not needed. The ICS/ICF status refers to whether or not either of the two options have been turned on.

ICS (Internet Connection Sharing) lets a computer share its Internet access with other computers on a local area network. It requires two network connections: one for the Internet, and one for the LAN. Thosetwo networks are completely separate from each other, each having its own IP subnet.
ICF (Internet Connection Firewall) prevents other Internet users from accessing your computer/network. You can enable or disable ICF individually on each network connection. Typically, it's enabled only on a direct modem (dial-up, DSL, cable) connection to the Internet.If it's enabled on a local area network, it blocks file and printer sharing between the networked computers.
You can use a 3rd-party firewall program instead of ICF. If you do,configure it to block access by other Internet users and allow access by other computers on your local area network. That typically involves specifying that your LAN is in a "trusted" zone.

A network bridge combines two or more physical networks into one logical network, with one IP subnet. It isn't generally possible to bridge an Internet connection. Windows XP doesn't let you bridge a firewalled network connection, and it doesn't let you firewall the network bridge itself.

With the release of Windows XP's Service Pack 2, Microsoft's Internet Connection Sharing (ICS) and Internet Connection Firewall (ICF) features quickly obtained a large degree of notoriety. Many developers have been actively looking for ways to easily "peek and poke" at the ICS & ICF configurations on a given machine.

Its good to know , these terms are very rare

You can use a 3rd-party firewall system program instead of ICF. If you do, configure it to prevent accessibility by other Online surfers and allow access by other computer systems on your lan. That typically involves specifying that your LAN is in a "trusted" place.
