NAT in 3G mobile networks

I like to dedicate the picture below to 3G mobile operators that deploy NAT in their networks:



The picture just say one part of the stories - congestion due to limited port numbers in a NATed outgoing IP address. There are other harms such as lack of end-to-end security and quick battery drain of mobile devices.

You think that 16 million private addresses in 10.0.0.0/8 (Class A, RFC1918) are large enough to serve all your subscribers. That's shit. Your subscribers deserve better quality of service.

Shame on you, 3G mobile operators !
