If I understand you right you have two WAN connectons, need to distinguish them on packet level and match against the WAN link from the control panel?

In Windows multiply WAN connections can be established through NDISWANIP interface, on the packet level they can be distinguished my their MAC addresses. Regretfully, there is no strighforward way to match WAN link to the WAN connection name in the control panel. However, it can be done through quick packet analyses. You can get source IP address from the packet and match it against against the connection using IP helper/RAS API. Each WAN link has a single IP address assigned and it uniquly identifies the connection.
