Hi,
its not recommended, but Windows can act as a IP Router.
To enable routing set
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\IPEnableRouter to 1:
c:\>reg add HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters /v IPEnableRouter /D 1 /f
change the startup type of the service “Routing and Remote Access” to auto
sc config RemoteAccess start= auto
and start the service
sc start RemoteAccess
Thats it
