FastNetMon Advanced 2.0.385

Release date: 12 October, 2026
Version: 2.0.385

FastNetMon Advanced 2.0.385 introduces enhanced FlowSpec traffic filtering statistics, improved BGP announcement capabilities, and TLS support for ClickHouse connections. This release also expands flow dump data and Prometheus metrics, upgrades scrubbing services, and addresses multiple stability issues related to traffic monitoring and data export.

Changes:

• Added TLS support for ClickHouse connections in traffic_db
• Added attack detection logic for IPv6 traffic
• Added flow_duration, flow_start, and flow_end fields to the JSON output of flow dumps
• Added per-IP counters to track traffic filtered by FlowSpec rules, accessible using sudo fcli show flowspec_host_drop_counters_v4 1.2.3.4
• Added bandwidth calculation for traffic filtered by individual FlowSpec rules, accessible using sudo fcli show flowspec_drop_counters_v4 UUID
• Implemented flow tracking for IPv6 traffic
• Upgraded scrubbing services to a newer version
• Added support for mirror next-hop configuration for IPv4 and IPv6 whole-subnet BGP announcements, using options such as gobgp_announce_whole_subnet_mirror_next_hop_ipv4 and gobgp_announce_whole_subnet_mirror_peer_name_ipv4
• Fixed a potential crash caused by an incorrect code definition in remote host counters
• Fixed a bug that could cause the ClickHouse exporter to crash when a database table is corrupted in FastNetMon or traffic_db
• Added version and license information to the Prometheus metrics endpoint
