Seamlessly manage IPv4 address depletion and IPv6 migration

Service providers need to manage IPv4 devices while transitioning to newer IPv6 devices and applications. Because IPv6 devices and content are not backwards compatible with IPv4, IPv6 migration strategies need to support the coexistence of both. BIG-IP CGNAT provides carrier-grade scalability with a high number of IP address translations, fast NAT translation setup rates and high-speed logging.


  • Conserve Publicly Routable IPv4 Address Space - NAPT and PBA let service providers exponentially scale available source addresses, up to a 35-to-1 return on a large-scale NAT (LSN) pool resource.
  • NAT for IPv4 and IPv6 Connectivity - A wide range of functionality includes NAT 44, NAT 64, Deterministic NAT, 464XLAT and DNS 64.
  • Carrier-Grade Performance - BIG-IP CGNAT handles close to 1.5 billion concurrent sessions and more than 1 Tbps of throughput, along with high-performance high-speed logging (HSL).

BIG-IP CGNAT as part of a security policy

BIG-IP CGNAT can be combined with BIG-IP Advanced Firewall Manager (AFM) to provide a comprehensive security platform. A consolidated approach results in simpler management and operation, reduced operational costs, and more opportunities to monetize functions and services.


  • High Performance Firewall - Combined with BIG-IP AFM, BIG-IP CGNAT provides the benefits of a high-performance firewall. These include a subscriber aware network firewall with integrated ACLs, IPS, and DDoS protections.
  • Subscriber Awareness - Subscriber awareness enables log enrichment with subscriber ID for CGNAT NAPT and PBA logs, subscriber discovery, and dynamic policy provisioning.

Consolidated N6 / S/Gi LAN solution

BIG-IP CGNAT can form part of a consolidated S/Gi-LAN or N6 LAN in 5G networks with DNS, edge firewall, DDoS, video traffic management, and more. A consolidated approach results in simpler management and operation, reduced operational costs, and more opportunities to monetize functions and services. 


  • Reduced CapEx and OpEx Costs - Up to 60% TCO savings through reduced VMs and single-hop design.
  • Simplified Architecture - Easier to deploy, manage maintain and scale.
  • Increased Services Velocity - Easier to add and roll out new services.
