[nsp-sec] User identification on a NAT:d 3G network?

[Huopio Kauto]

There seems to be an increasing pressure to move into providing NAT-provisioned 
3G data service. How the service providers have solved the "identifying the infected
customer" -problem? NAT logs - any practical recommendations? What is the 
"NAT compression ratio" used on 3G NAT cases?
