    Click Start, click Run, type services. msc and click OK at this point.Find Windows Firewall/Internet Connection Sharing (ICS) in the list of skills. Notice that the state of the custom service is “Started”.For guidance on using the Services feature, simply click Help from the action menu.

    [Internet Connection Firewall may have changed or become unavailable if you stick to versions. Instead, use Windows Firewall API.]

    When using Internet Connection Sharing in conjunction with the Internet Connection Firewall (ICS/ICF) API, you often allow applications to enable, disable, and configure these services.

    Note All users have access to playback configuration settings. However, admin rights are required to extend ICF configuration options.

    Using the ICS/ICF API, you can easily allow applications to enumerate ports, enable or disable ICS on a per-connection basis, and configure connection mappings for ICS and ICF. ICF cannot be enabled for a Site Bridge connection, the connections are bridge members, independent ICS connection, IrDA connection, or directSecond cable connection (DCC).

    Changing the port mapping directly from the ICS/ICF API will cause this notice to be displayed locally on the computer’s visitor interface.

    When using Windows XP Serviced (SP2) Pack 2, an API is required to open the inbox or enable or disable software in the interface without additional user confirmation. The dialog box was not displayed as a result of calling any of these APIs.

    The ICS/ICF API only changes the local machine type. Applications that create interface mappings on a remote ICS computing device or Internet Gateway Device (IGD) require the use of the NAT Traversal API.

    Internet Connection Sharing (ICS) SoftwareAllows small offices and individual users to have one Internet connection. Internet Connection Firewall (ICF) covers connections through which it is accepted as unwanted network traffic. The ICS/ICF API allows you to programmatically control ICS/ICF functionality and create, enable, and use Disable ICS or ICF port mappings directly over a network connection.

    If Applicable

    The ICS/ICF API is intended for situations where the vendor of a software application or device needs to make adjustments to the actual configuration of the home network on which it is running. For example, a service that is connected to the Internet through a local network address translator (NAT) and is expected to receive unwanted traffic could write a port mapping through the NAT traversal API.

    Another example, an application that provides advanced firewall or NAT functionality may cause the ICS/ICF API to disable ICS for certain connections with the permission of the client.

    ICS is available for this specific use on the operating systems listed in sectionle requirements below. It may be switched or not available in later versions. ICF will be changed or not available in later versions. Instead, use the Windows Firewall API.

    This article describes how to install Internet Connection Sharing (ICS) on a computer that is running Microsoft Windows Server 2003.


    How do I enable Internet Connection Sharing?

    Click Start, Settings, Control Panel, Network and Remote Connections, [RAS Connection].Click Properties.Select multiple sharing tabs.Select Turn on Internet Sharing for this connection.

    ICS allows you to connect Windows Server 2003 to a small office or home network over the Internet. ICS provides network address translation (NAT), IP addressing, and name screen resolution services for all PCs in small networks.

  • Digital Subscriber Band (DSL) or cable modem connected to an Internet Service Provider (ISP) and then DSL or cable enabled.
  • Two network adapters installed. This article describes how to install a link on the second adapter.
  • A network that already has TCP/IP configured.
  • Before proceeding with the procedures in this article, note the following:

  • How do I allow network sharing on my firewall?

    Open Control Panel, click System and Security, then click Windows Firewall. In the left pane, click Advanced Options, and in that console tree, click Prules for incoming connections. In the Inbound Rules section, find the File and Printer Sharing (NB-Session-In) and File and Printer Sharing (SMB-In) rules.

    Do not use ICS on a website that:

  • Use Static IP addresses

  • Has a Windows Server 2003 PDC

  • How do I enable ICS in Windows 10?

    Right-click your Internet connection and select Properties. Click on the Sharing tab. Check the box next to Allow many other network users to connect to the Internet through this type of computer to enable and/or disable Internet Connection Sharing (ICS).

    Use other DNS servers, gateways, or DHCP servers

    Because ICS generates the required static IP address for your network adapter and assigns IP addresses to other computers on your current network, you will lose network connectivity to the rest of the network system if other computers on the network have already granted you these benefits. If your current network has one or more of these conditions, you should use Windows Server 2003 NAT instead of ICS. For more information about NAT, see Windows Server 2003 Help.

    Do not create a VPN (virtual private network) connection between the ICS computer and the corporate network. When you do this, all traffic on behalf of ICS, including traffic from local Internet connection clients, is routed through our VPN connection to the corporate computer network. This means that the Internet resource will almost certainly become unavailable, and most client computers will move data over the logical connection established with the user’s credentials ICS computer.
