Filecatalyst Firewall Jun 2026

While opening ports is necessary, security should not be compromised. Here are three best practices for a secure FileCatalyst firewall setup:

If you need to manage your FileCatalyst server from a remote location using the Remote Administration tool: Open TCP port 12400 . Navigating Network Address Translation (NAT) While opening ports is necessary, security should not

UDP for the actual accelerated file transfers. Required Port Configurations TCP Port 21 (Control Channel): Used for the initial connection and command exchange (standard FTP/FTPS control port). UDP Ports 4500–4505 (Data Channel): These are the default ports used for the accelerated data transfer. TCP Port 12400 (Remote Administration): The default port for the FileCatalyst Server Remote Admin interface. TCP Port 12401 (HTTP/HTTPS): Used for web-based transfers and the FileCatalyst TransferAgent. Firewall & NAT Considerations Inbound Rules: Your firewall must allow inbound UDP traffic on the specified data ports (e.g., 4500–4505) to the FileCatalyst Server. Outbound Rules: Ensure the server can send UDP packets back to the client on the negotiated ports. Masquerade Address: If the server is behind NAT, you must configure the Navigating Network Address Translation (NAT) UDP for the

When it comes to large file transfers, speed is king. That is why tools like FileCatalyst have become the industry standard for media, entertainment, and enterprise organizations—they bypass the bottlenecks of standard TCP transfers to deliver files at lightning speeds.

Open TCP Port 21 for inbound connections on the server-side firewall.

Each concurrent transfer session requires its own UDP port. If you expect more than 100 simultaneous transfers, you should expand this range accordingly in both the software and the firewall. 3. Remote Administration (TCP Port 12400)
