Host an OpenFusion Server

OpenFusion can be run as a local or community server. Start locally, keep the server and client versions matched, and expose a port to the internet only after you understand the security and network implications.

Public hosting needs additional care

Port forwarding, firewall rules, updates, logs and account security become your responsibility when other people can connect. Do not expose an untested server or reuse credentials from your forum or hosting panel.

  • Use unique credentials.
  • Back up before updating.
  • Keep the operating system and server build maintained.

Confirm the current server instructions

Configuration details can change between releases. The FusionFall community hub can point you to the current server package, release notes and live setup help while this guide keeps the core version-matching and local-testing workflow in one place.

  • Match the server package to Original or Academy.
  • Test on 127.0.0.1 before opening a firewall port.
  • Back up configuration and account data before updating.
