The operational basics for installing TuffNode, configuring runtime resources, Shield and add-ons.
Plain-language setup for TCP 25565, Windows Firewall, router rules, CGNAT, double NAT, ISP limitations, whitelist and online-mode safety.
Install TuffNode on Windows and get to the first managed server.
Windows 10/11 x64 desktop application.
Use the TuffNode installer, then launch the app from Start or the desktop shortcut.
Create a new server or import an existing server folder without moving its files.
Set JVM memory deliberately instead of guessing.
Minimum and maximum server memory are configurable per server.
Community defaults the minimum heap to 512 MB and applies runtime changes on the next restart.
Leave enough physical memory available for Windows and the Minecraft client when they share the same PC.
Control local IP enforcement for managed servers.
Trusted addresses take precedence over blocked entries.
Shield scopes Windows Firewall rules to active server ports when host-level enforcement is available.
Managed servers also support Minecraft-level IP blocking as a fallback enforcement path.
Browse, install and maintain server extensions from one workspace.
Community supports plugins, mods and datapacks through compatible providers and local files.
Installed add-ons can be enabled, disabled or uninstalled from the application.
Compatibility still depends on the selected Minecraft version, loader and server software.
