Ready to host your own factory? In this updated 2026 guide, Eric walks you through the complete process of setting up a Satisfactory Dedicated Server following the 1.2 update. A lot has changed since our last tutorial—specifically the default ports! If you are having connection issues, it is likely because you are using the old ports. This video covers everything from downloading Steam CMD and using the correct App ID (169080) to creating custom .bat files for auto-updating and launching your server. We also dive into the critical port forwarding steps for 7777 (TCP/UDP) and 8888 (TCP). Finally, learn how to use the in-game Server Manager to claim your server, set admin passwords, and troubleshoot common UI bugs. Whether you are a FICSIT veteran or a new Pioneer, this step-by-step tutorial ensures your multiplayer experience is lag-free and always online.
