> Symmetric NAT is just pointless. Fair enough, I don't know enough about usage of different NAT types to debate such things (and never intended to). Regarding tracking, I'm still not sure that we're talking about the same thing here. Are you saying that fingerprinting could be used to accurately extract per-device data from the aggregated stream? That is, if an entire network is hosted behind a single external address via NAT, are you suggesting that the carrier could reconstruct the separate fingerprints from the aggregate data stream that they have access to? If so, that would be news to me. Obviously they can make some educated guesses (a single device probably isn't originating simultaneous Netflix and YouTube video streams), but I'm assuming that aggregated (TLS encrypted) data streams are going to be fairly difficult for an external observer to tease apart.
