For those who don’t get the joke, NAT devices that track flows do so via what’re called ephemeral ports, of which there are only 65,535 ports on any single IP. So if we assume all ports are use for ephemeral purposes, it means that a grand total of 65,535 CONNECTIONS (more on that later) are possible at any given moment. Now when I say connections, modern browsers will open multiple connections simultaneously to increase load speed (it’s called pipelining). So one web page could open 10-20 connections. Then, frequently with dynamic content, some of those connections are left open to load content as it flows in (email, DMs, etc). All this to say that limiting a whole country limits millions or billions of people to 65,535 of which each web page will occupy 10-20. So you’re in effect taking the internet beyond the NAT device offline, as millions have to compete for what amount to 3,000-6,000 possible slots to access the internet. Thank you for reading my ‘tism, I’m a network enginerd at the end of the day so this is my special interest.
