Well, but if your Windowscomputer has a public IP (which means is directly connected to your ISP via ppp), you'll have to activate routing and NAT on the Windowscomputer. This means that the Windowcomputer creates his own local network with one of the VM-NICs, but it is as I wrote above, the Subnet of your Windowscomputers VM-NIC and your Linuxcomputers must be equal. In your case, when the IP-adress in Windows is 192.168.184.xxx with mask 255.255.255.0 then the Linuxcomputer must have an adress 192.168.184.yyy.

In your above screenshots this is not the case.
