LabelsFileMaker – name binding and transport

Synopsis

  • TCP port 5003 is the registered port for Claris/FileMaker database networking.
  • FileMaker Server (Windows/macOS) listens on 5003 for client connections from FileMaker Pro and FileMaker Go to open and use hosted databases.
  • Real-world deployments expose 5003 on LANs and sometimes via VPN or controlled internet access for remote FileMaker users.
  • Legacy and current FileMaker versions (e.g., 7 through modern releases) use this same port for the core database session protocol.
  • IANA documents 5003/TCP as assigned to FileMaker.
  • Security note: attackers and scanners routinely probe 5003 to find internet-exposed FileMaker servers, and misconfigurations or past vulnerabilities have been exploited; limit exposure or place behind VPN/reverse proxy.
