그냥 pfSense 깔고 연동하면 되는데 음...

라우터에서 IPSec 터널링 하고 라우팅 설정 해줘도 되고

2) 오픈소스 기반 NMS 및 Flow Monitor 구축

...

2-2) Flow Monitor 구축 (2종)

• NetFlow, sFlow data → ElastiFlow Flow Collector (Logstash) → Elastic → Kibana
• NetFlow, sFlow data → NetSage (ELK + Grafana)

AFAIK telegraf is already using GETBULK, you can configure it by using the max_repetitions config setting (defaults to 10).
