CGNAT Syslog Compliance Logging Platform
Meet regulatory CGNAT logging requirements with Kashtrix's carrier-grade syslog platform. Ingest high-frequency NAT translation logs from MikroTik, Cisco, Nokia and Huawei gateways, map public IP-port allocations to subscriber profiles, and maintain encrypted archives with instant subpoena search.
Why CGNAT Compliance Matters
As IPv4 address exhaustion continues, ISPs increasingly deploy Carrier-Grade NAT (NAT444/DS-Lite) to share public addresses across subscribers. This creates a legal and operational challenge: when law enforcement or regulatory bodies request identification of a subscriber behind a specific public IP at a specific time, the ISP must produce port-level NAT translation logs that map back to individual accounts.
Without proper logging, ISPs risk regulatory penalties, inability to comply with lawful intercept requests, and audit failures. Kashtrix Syslog provides the infrastructure to capture, index, archive and search these critical CGNAT translation events at scale.
Platform Capabilities
High-Throughput Syslog Ingestion
Receive syslog streams via UDP, TCP and TLS (port 514). Supports MikroTik, Cisco ASR, Nokia, Huawei and other NAT gateway log formats with vendor-specific parsers.
Subscriber IP-Port Mapping
Automatically correlate NAT translation events (public IP + port range) with subscriber profiles from the Kashtrix CRM/BSS database. Provides instant subscriber identification for any IP-port-timestamp query.
Encrypted Hot/Cold Archival
Recent logs are stored in hot searchable indexes for sub-second queries. Older logs tier to encrypted cold storage (S3-compatible) with configurable retention policies.
Audit Search Interface
Purpose-built search interface for compliance officers and law enforcement queries. Search by public IP, port range, timestamp, subscriber ID or geographic region with export-ready results.
Frequently Asked Questions
What is CGNAT compliance logging?
Carrier-Grade NAT (CGNAT) allows ISPs to share public IPv4 addresses across multiple subscribers using port-based allocation. Regulatory requirements in many jurisdictions mandate that ISPs log these NAT translations — mapping public IP addresses and port ranges to specific subscriber accounts — and retain them for audit and law enforcement purposes.
How many syslog messages can Kashtrix process?
Kashtrix syslog is designed for high-throughput ingestion via UDP, TCP and TLS on port 514. The architecture supports horizontal scaling to handle growing log volumes as your subscriber base expands.
How long are CGNAT logs retained?
Kashtrix supports configurable retention policies with encrypted hot/cold storage tiers. Hot storage enables sub-second search across recent logs, while cold archival to S3-compatible storage provides long-term compliance retention.
