Hello, I'm trying to configure w10 as router to share mobile broadband which is connected to win10.
My hardware is like the following:
LAN -- W10 -- mobile usb MODEM ---> internet.
192.168.137.0/24 --- 192.168.137.2 on ethernet and ip alias 192.168.137.1 on cellular net ----> default gw.
I just want route all the lan traffic through the windows10 box to the internet.
I overcome some obstacles ... for example the mobile connection goes down when I connected the ethernet cable. Then I enabled the following reg entry to enable both interface to work:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WcmSvc\Local\fMinimizeConnections DWORD32 ---> 0
also I enabled the routing ip with the following reg entry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\IpEnableRouter DWORD32 ----> 1
I also tried to share the internet connection from the ethernet interface making right click on the eth interface --> share internet connection..
anyway now I fired up a traffic capture software and I see the ping that come from lan (on my other pc) that should go to 8.8.8.8 then it's redirect to the cellulare net gateway but it's not routed... I show you the result from the sniffer:
