Anthony,
sorry but i do not understand.

Suppose workstation is 192.168.1.2 and connects to youtube 64.15.126.98 using a 
NAT address a.b.c.d

If you analyse traffic on the internal interface, you will see 192.168.1.2 <-> 
64.15.126.98, whereas on the extern a.b.c.d <-> 64.15.126.98. THis with the 
ntopng and ntop.

if I understand correctly you would like to see if ntopng can say that 
192.168.1.2 is mapped to a.b.c.d?

Luca
