Release date: 16 October, 2025
Version: 2.0.373
FastNetMon Advanced 2.0.373 has been released with security hardening, telemetry enhancements, and new integrations. We’ve added device allow-lists for Netflow v5/v9 and IPFIX collectors and introduced a Flow Spec–based allow list to tighten policy control. AF_PACKET mode now populates input/output interfaces using kernel interface indices, and usage telemetry can export internal and other traffic classes. This release adds GCore support for scrubbing integration and improves troubleshooting by printing the sFlow agent IP when sample parsing fails. Breaking change: sudo fcli show traffic_buffer now returns packets in JSON instead of writing them to the log. We also enabled CGNAT use for internal IPs on external licenses and deprecated CentOS 7. Full details below.
Full list of changes:
- Added logic to print agent IP address when we have error with parsing sFlow samples
- Added logic to export other and internal traffic in usage telemetry
- Breaking change: sudo fcli show traffic_buffer will start returning packets in JSON instead of logging them to log file
- Added GCore support for scrubbing integration
- Update scrubbing integration to latest version to add gCore support
- Added full logic to implement Flow Spec based allow list
- Added logic to lock down Netflow v5, v9 and IPFIX to only specific list of routers: ipfix_devices_allow_list, netflow_v9_devices_allow_list, netflow_v5_devices_allow_list
- Added logic to populate input and output interfaces information in AF_PACKET mode by using internal linux network number which can be got via sudo ip link in first column
- Allowed usage of CGNAT for internal IP address for external licenses
- Deprecated CentOS 7
