I'm going to try to simplify it down to make it make some sense.
Think of the ESN like a license plate on your car, and the router like a gate guard to a gated community (or WDW resort, if you'd prefer).
The gate guard will let pretty much anyone LEAVE (ie: sends all traffic out to the larger network) but watches the traffic and will only let IN the traffic with the right license plate numbers (ESN's) that are on it's "list". Oh, and every time a car leaves, the gate guard plunks a big old sticker on your windshield. That helps the old guy to make sure he can flag you down when you whiz by him, so you don't take a wrong turn.
Now, to make it more complex, there is ANOTHER gate guard (probably more than one) that controls traffic into and out of Dinsney's overall "neighborhood" (ie network). THAT gateguard is watching both your license plate AND the sticker on your windshield. That way it knows exactly where you belong so it can better route traffic to the right place. By looking at those license plates and stickers, it can tell just how many licesnse plates belong to any stickers. It's POSSIBLE that it could be configured to only allow ONE license plate per sticker OR that if it sees stickers of the wrong color, shape, or size at all (in other words, routers not specifically allowed to access it's network), it could not let you leave/return.
That's vastly oversimplified, but it's a relatively clear picture on how Disney can monitor router traffic coming through it's network.
Thank you for that visualization!
