Mike: Unfortunately, in your situation, the customer-private addresses are lost, and you cannot see them. The MAC address is not retained. All you could tell them is where their traffic is going on the Internet side of things. To view traffic inside their own networks, they would have to run some sort of exporter technology themselves...
