Defining an Ephemeral Port Range

FME Flow makes use of ephemeral ports. For certain processes, ports are used to establish an initial connection, after which another random port is opened for dedicated communication, freeing up the original port to connect with other services. If your FME Flow installation distributes components across a network in a locked-down environment with strict firewall rules, you must define a dedicated pool of ports that FME Flow can use for the random port assignment.

  1. Open fmeFlowConfig.txt.
  2. Locate parameter FME_SERVER_PORT_POOL, under FME SERVER SETTINGS START > Port and Host Assignments.
  3. The default value is 0, meaning the dedicated port assignment is random. Change the parameter to a valid range of available ports. For example, 7100-7150.
  4. Repeat steps 2-3 with the files that correspond to the following FME Flow Web Services:
    • fmerest
    • fmedatadownload
    • fmedatastreaming
    • fmejobsubmitter
    • fmenotification
  5. Restart the FME Flow Application Server, FME Flow Core, and FME Flow Engines services to apply these changes.
  6. Create the associated firewall exceptions for this range.
