Why logging matters
When an IP address is shared by many subscribers, the address alone does not identify who was online. Licensed operators are expected to be able to trace activity back to a subscriber when legally required.
What to record
At minimum: the subscriber identifier, the private address, the public address, the port range and the start and end time of the allocation. Timestamps must be accurate — synchronise clocks with NTP.
Port block allocation
Instead of logging every connection, CGNAT can assign each subscriber a block of ports for a period and log only the allocation. This reduces log volume dramatically while preserving traceability.
Retention and access
Follow the retention periods in your licence conditions and applicable rules. Restrict access to logs and record who queries them.
Treat logs as personal data
NAT logs link people to their online activity. Protect them under your data protection programme, including the obligations of the DPDP Act.
Not legal advice
Requirements evolve. Confirm specifics with your regulatory and legal advisers.
Peer1IX NAT Gateway includes configurable logging to support these obligations.
