Sony Entertainment is know to be slowpoke in this area. PS4 firmware/kernel is SLAC enabled IPv6 but its not exposed to devs and thus apps doesn't use it at all. Are you sure about ATV4 netflix app? Support is there and I've seen traffic from it when recently did tcpdump from ATV4. On 28/11/18

Not exactly. You don't need to advertise the RFC1918 to the OCA - just make sure you advertise the CGN prefix to it, and make sure that the OCA's default gateway knows how to reach the RFC1918 clients. So long as the "outside" IP of your CGN is advertised to the OCA (the IP that clients who would
