Satisfactory

Satisfactory uses TCP+UDP on its main port and, on newer builds, also expects a separate reliable TCP port. Swarm Hosts persists the server files under /serverdata.

Launch Notes

  1. Choose Satisfactory.
  2. Keep the default launch flags unless you have a specific networking reason to change them.
  3. Older community guides often mention 15000/udp and 15777/udp; current setups usually center on the published game port and reliable TCP port instead.

Connect

Add the server in Satisfactory's Server Manager using the published host and primary port.
