In some implementations, a redundant DBNG user plane device may maintain respective subscriber states of a plurality of primary DBNG user plane devices. The redundant DBNG user plane device may determine, based on maintaining the respective subscriber states of the plurality of primary DBNG user plane devices, that a particular primary DBNG user plane device, of the plurality of primary DBNG user plane devices, is not active. The redundant DBNG user plane device may identify, based on determining that the particular primary DBNG user plane device is not active, a subscriber state of the particular primary DBNG user plane device. The redundant DBNG user plane device may operate, using the subscriber state of the particular primary DBNG user plane device, as an active DBNG user plane device for traffic associated with the particular primary DBNG user plane device.

Techniques are described for performing subscriber-aware NAT functions. In one example, routers or other NAT-enabled devices deployed within a network are configured to auto-correlate subscriber information with NAT operations performed by the devices when forwarding network traffic. As such, the techniques offload the burden of correlating subscriber login activity with NAT operations as typically performed by offline NAT log archive systems.
