Technical Details

what runs on :16020

The IANA assignment identifies TCP 16020 as FileMaker Java Web Publishing Core. It is associated with the Java Web Publishing component in FileMaker Server deployments. The available assignment information does not specify a public wire protocol, handshake, or framing, so do not assume it behaves like a normal HTTP listener; it is best understood as a FileMaker-specific component port rather than a general web-service endpoint.
