2 Comments

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
