UDP 5003
Synopsis
- FileMaker Pro and FileMaker Server (Claris) use UDP port 5003 for LAN host discovery; clients broadcast on UDP 5003 to find available FileMaker servers, then establish the actual database connection over TCP 5003.
- This is used in real deployments on Windows and macOS across many FileMaker versions (e.g., FileMaker Pro/Server 7–19).
