Carrier-Grade NAT (CGNAT)

Enterprise-class IPv4 address management for ISPs and large networks

The IPv4 Address Exhaustion Challenge

With IPv4 addresses exhausted globally, Philippine ISPs face a critical challenge: how to continue growing their subscriber base without purchasing expensive IP address blocks. Traditional NAT solutions don't scale to carrier requirements, creating bottlenecks and management headaches.

Small ISPs using consumer-grade routers or basic NAT implementations struggle with connection limits, logging requirements for legal compliance, and the inability to fairly share addresses across subscribers.

Juniper MX CGNAT Solution

Juniper MX routers provide hardware-accelerated CGNAT that can handle millions of concurrent connections while maintaining deterministic performance. The solution includes comprehensive logging for NTC compliance and sophisticated algorithms for fair address pool sharing.

Our NaaS platform includes fully managed CGNAT with automatic pool management, monitoring, and optimization. We handle the complex configuration, ensuring your subscribers get reliable internet access while you stay compliant with regulations.

How It Helps ISPs

  • Scale to 100,000+ subscribers on a single public IPv4 block
  • Maintain NTC-required connection logs without performance impact
  • Automatic port allocation prevents subscriber service degradation
  • Real-time monitoring shows pool utilization and subscriber patterns
  • No need to purchase additional IPv4 addresses as you grow

How It Helps End-Users

  • Consistent internet performance even during peak hours
  • Support for popular applications and gaming (with proper ALG configuration)
  • No unexpected connection drops or slowdowns
  • Transparent operation - subscribers don't notice NAT is happening
  • Compatible with CGNAT-aware applications and services

Why MikroTik CCR Falls Short

  • Limited concurrent session capacity causes dropped connections
  • Basic logging doesn't meet regulatory requirements
  • Port allocation algorithms can create unfair resource distribution
  • Performance degrades significantly under high load
  • No hardware acceleration for NAT operations
  • Difficult to troubleshoot subscriber-specific issues
