No, it eliminates TRIPLE NAT: Carrier NAT (CGNAT) + Amplimax Ultra internal NAT + Your routers own NAT. 3 different NATs for your traffic to traverse before it reaches the internet at large; or comes back.
NAT at it’s simplest means routing or traffic direction function. I asked Google AI to define NAT for me in simple terms and this is what it output:
“Imagine your house has a big front door that everyone can see, and the street address in the door. That’s like a public IP address. But inside your house, you have lots of little doors to different rooms. Those are like private IP addresses.
NAT is like a friendly doorman who stands at the big front door. When someone knocks on the big door, the doorman knows which little door inside the house to send them to. So, even though there’s only one big door, lots of people can come and go through different little doors inside.
That’s how NAT works on the internet. It helps lots of devices use just one public IP address to connect to the internet.”
CGNAT is the one that confuses a LOT of people. Consider the carrier network to be a like a huge private network that does NOT generally assign you a publicly accessible IP address (it sometimes happens on some carriers, but this is not reliable unless you pay them for a public IP). Instead the carrier network will assign you one if it’s privately owned IPs, just like your home router assigns your computer it’s own IP address from your routers IP pool (think 192.168.1.x etc). This means that even though you have your home router, they are running your traffic through their router as well, before it hits the internet on THEIR public IPs. These public IPs are being used to route your traffic along with THOUSANDS of other customers; on the exact same IPs. This is why you may have seen a huge spike in those “prove your not a robot” challenges on website logins, after you moved to cellular internet.
So now you have your CGNAT, and you have your carrier supplied gateway modem/routers NAT. That’s double NAT. If you added your own router to the mix, like a TP-Link, Ubiquity, Netgear, ASUS, etc, then you added a 3rd NAT,for Triple NAT. Replacing the carrier gateway with an Amplimax Ultra, doesn’t eliminate a NAT, it takes the place of one.
If you put the Amplimax Ultra in “bridge mode” then you DO eliminate it’s own NAT, but it doesn’t magically also eliminate your home routers NAT or the carriers CGNAT, so you still have double NAT.
