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 disabled by default.
If packets are leaking from a host-only network on a Windows host system, check whether packet forwarding is enabled on the host system. If packet forwarding is enabled, you must disable it.
Procedure
- ♦ On a Windows Vista or Windows 7 or later host, stop the Routing and Remote Access service.
- Type services.msc to open the Services Console.
- Select Routing and Remote Access and click Stop.
