Summary
Real-time logging of every NAT session for traceability and auditing. Blocks unauthorized port forwarding to protect against misuse. Optimises IPv4 use and facilitates seamless IPv6 adoption. Minimal storage yet high throughput for large networks. Easier integration with firewall & traffic management systems. Built for ISPs / telcos with demands on scale, security, and compliance.
Overview
A high-performance tool designed for Internet Service Providers, telecom operators, and data centres to handle massive volumes of NAT sessions in real time. It gives full traceability, optimised use of limited IPv4 space, and smooth migration paths toward IPv6 — all without adding complexity or degrading network performance.
Key Features & Capabilities
Continuous, accurate logging of all address translations and sessions, enabling instant audits and full accountability.
Stops unauthorized port forwarding, ensuring ports aren’t abused or misconfigured in ways that compromise security.
Extends the life of your IPv4 addresses by using them more efficiently, while providing tools for seamless transition into IPv6.
Logs adhere to regulatory and certification needs — recording what’s needed without
excess bloat.
Handles millions of NAT sessions per second, with minimal storage overhead. Designed for scale.
Logs stored locally (e.g. via syslog), making integration with monitoring, reporting, and firewall systems straightforward.
Works with existing firewall tools (for example, BIG-IP AFM etc.) to ensure tight control and better synergy in traffic security.
Engineered for continuous operation under load; supports ISPs / telcos with large subscriber bases without bottlenecks.
Who It’s For
How We Compare
| Feature/Capability | Legacy or Basic NAT/Carrier NAT Tools | Your NAT Logging & Transition Solution (What to Emphasize) |
|---|---|---|
| Session Trace/Logging Detail | Often limited logging (just basic start/end, maybe summarised); may miss detailed per-session metadata. | Rich session logs: when, who, which port, translated address, duration; full detail for auditing. |
| Security: Port Misuse Control | Port forwarding often not strictly controlled; risk of misuse or abuse. | Built-in prevention of unauthorized port forwarding; mapping with external interface to ensure visibility. |
| IPv4 Utilization & IPv6 Transition | IPv4 often under strain; many systems not ready for IPv6; migration is expensive and disruptive. | Tools that allow maximising current IPv4 address use and provide phased, low-impact migration to IPv6. |
| Performance & Scale | Some legacy systems struggle when session counts scale into millions; storage/indexing becomes bottleneck. | Designed for high throughput: supports millions of concurrent NAT sessions with minimal storage footprint. |
| Compliance & Audit Support | Logs may not satisfy strict regulatory requirements; sometimes delays or gaps in logging. | Logs structured and stored for compliance; real-time visibility; stored locally for audit. |
| Integration with Firewall/Security Systems | May require custom adapters or scrapping together logs; sometimes firewall integration lags. | Seamless compatibility with existing firewall/traffic management tools; log forwarding; security synergy. |
| Resource/Storage Efficiency | High storage overhead or very simplistic purging; can become costly with scaling. | Optimised storage; efficient retention strategies; only storing necessary data; minimal waste. |
| Ease of Deployment & Maintenance | May require extensive custom configuration; legacy hardware/software constraints. | Designed for smoother integration; fewer customizations required; maintainable under large loads. |
| Cost vs Value | Lower upfront cost but higher hidden costs: scaling, compliance, reinvestment as IPv4 becomes scarcer. | Emphasise long-term value: risk mitigation, reduced compliance headaches, extended viability of IPv4 investment. |
