ICS and VPN connections

If you create a virtual private network (VPN) connection on your host computer to a corporate network and then enable ICS on that connection, all Internet traffic is routed to the corporate network and all of the computers on your home network can access the corporate network. If you don't enable ICS on the VPN connection, other computers will not have access to the Internet or corporate network while the VPN connection is active on the host computer.

Configure TCP/IP

To use ICS, make sure the local area network (LAN) connection on each network computer is configured to get an IP address automatically. To do this:

   1.

      Open Network Connections by clicking the Start button Picture of the Start button, clicking Control Panel, clicking Network and Internet, clicking Network and Sharing Center, and then clicking Manage network connections.
   2.

      Right-click the LAN connection, and then click Properties. Administrator permission required If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
   3.

      Click Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6), and then click Properties.
   4.

      Click Obtain an IP address automatically or Obtain an IPv6 address automatically.

The Internet options on your network computers should also be configured for ICS. For more information, see Change Internet settings for ICS (Internet Connection Sharing).

Do not use ICS on a network with domain controllers, DNS servers, gateways, or DHCP servers. And don't use ICS on systems configured for static IP addresses.

To enable ICS, on your host computer:

   1.

      Open Network Connections by clicking the Start button Picture of the Start button, clicking Control Panel, clicking Network and Internet, clicking Network and Sharing Center, and then clicking Manage network connections.
   2.

      Right-click the connection that you want to share, and then click Properties. Administrator permission required If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
   3.

      Click the Sharing tab, and then select the Allow other network users to connect through this computer’s Internet connection check box.


Hope this helps
