NAT and CoA

RADIUS Change of Authorization (CoA) can be used in subscriber management (ESM) to modify the NAT behavior of the subscriber. This can be performed by:

• replacing a NAT policy in a subscriber profile for the L2-Aware NAT subscriber

• replacing or removing a NAT policy within the IP filter for the ESM subscriber using LSN44, DS-Lite or NAT64

• modifying DNAT parameters directly via CoA for the L2-Aware subscriber
