Systems that use server versions of Windows operating systems can forward IP packets that are not addressed to them. These systems, and Windows Vista and Windows 7 and later systems, have IP packet forwarding turned off by default.

If packets are leaking from a host-only network on a Windows host system, check whether packet forwarding is turned off on the host system. If packet forwarding is turned on, you must turn it off.

Procedure

  • ♦ On a Windows Vista or Windows 7 or later host, stop the Routing and Remote Access service.
    1. Type services.msc to open the Services Console.
    2. Select Routing and Remote Access and click Stop.
