> the outside world sees my router's IP and that's it. At some point, that will go away due to CGNAT. A lot of people have to share their public IPv4 address these days, which means no inbound port forwarding, and potentially getting banned from services if their "neighbors" misbehave. On the other hand, CGNAT does improve privacy to some extent.
