the network card (nVidia built-in Nic), appears in NETWORK MANAGER Aplet.
But it does not appear in Yast2–>Security_and_Users–>Firewall–Interfaces.
So this is a hassle in order to configure for instance “Masquerade” for Internet Sharing.
It is also a problem for DHCP server configuration as this interface or NIC is the one connected to the local network in order to give IP private-addresses (non-routable)
One thing I noticed is that right-clicking on the Network Manager icon and selecting “Connection Information”, this NIC appears with a driver called “FORCEDETH”
