Use ActiveSync to "pass through" this computer. That means the connected device can use the computer's network connection as if it were its own. You can use this feature to perform tasks such as downloading non-Outlook e-mail messages, to connect directly with Microsoft Exchange, or to browse the Internet.
Important Note For additional security, disable network bridging on the PC (specifically, bridging to a Remote NDIS adapter) before connecting to the PC to pass though to the Internet or a network. For more information on network bridging, see Windows Help on the PC.
