I have an Internet facing 3800 router and looking at the netflow and nbar results (using the GUI) I see some traffic that should not be on the network such as vdolive, napster,pcanywhere,edonkey, etc.
When I try to view the toptalkers, I get a message saying that this IOS will not support this feature.
So how do I determine which IP's are initiating this specific traffic?
Is sniffer the answer? Anything on the IOS?
