There is no difference on the NDIS level between network adapter connected to the corporate network and internet adapter connected to the Internet. However, you can use IP HELPER API to query routing table, usually the default gateway interface (route 0.0.0.0 mask 0.0.0.0) is the Internet one. IP Helper API can be also used for enumeratimg active connections.
