Seems that a good number of scenarios that traditionally called for NAT gateways could be resolved by running IPv6 with an egress-only Internet Gateway (assuming the service you need to reach is IPv6 enabled).
Anyone attempted this approach? Seen any success?
With IPv6, you are global, not private, that’s why you need egress-only internet gateway to stop communication initiated from internet but still can talk to internet.
With NAT gateway, you don’t use public IPv4 address.
