Network Address Translation (NAT)

Monitor subscriber port utilization (cSRX, MX240, MX480, MX960, SRX1500, SRX1600, SRX2300, SRX4200, SRX4300, SRX4600, SRX5400, SRX5600, SRX5800, and vSRX3.0)―Use Carrier Grade Network Address Translation (CGNAT) to monitor and manage port utilization. Configure threshold limits to receive notifications when port or port block usage exceeds these thresholds.

If a pool is configured as Port Block Allocation (PBA) and a subscriber uses more port blocks than the threshold, a notification is generated.

For Deterministic NAT (DETNAT) pools, if a subscriber uses more ports than the threshold in the allocated block, a notification is generated.
