For example, assuming a range of 200 ports is defined by the operator for each user, when a subscriber with a private IP address of 10.0.0.1 wants to make a connection over the actual IP, a port range of 10000: 10200 for that actual IP address is allocated to that user.

NAT / port assignment is 100% up to the NAS. RADIUS is not involved at all.
