Filecatalyst Detection !!better!! Guide

In some high‑performance setups, FileCatalyst runs without TCP at all — no handshake, no keep‑alive, pure UDP data + UDP control. Most security tools assume a TCP control channel and will miss this entirely.

Detecting FileCatalyst is critical for three primary reasons: filecatalyst detection

Port 990 (TCP/SSL) for control; Ports 8000–8999 (TCP/UDP) for data; Port 12400 (TCP) for remote administration; Port 12480 (TCP) for web server broadcasts. In some high‑performance setups

Because the UDP data channel sends packets containing IP and port information in the payload, a standard NAT firewall that only alters the IP header will break the connection. Ports 8000–8999 (TCP/UDP) for data
