Trampoline
Running a Minecraft server network with BungeeCord offers incredible flexibility, but it also introduces a frustrating problem: player identities get lost in translation. When your backend servers are set to offline mode to work with the proxy, players lose their real UUIDs and custom skins. The Trampoline mod for Fabric solves this elegantly by implementing IP forwarding, ensuring every player retains their unique identity across your entire network.
What is the Trampoline Mod?
Trampoline is a lightweight Fabric mod designed specifically for server administrators who use BungeeCord to connect multiple Minecraft servers. It acts as a bridge, enabling IP forwarding so that the proxy can pass real player IP addresses and authentication data to the backend Fabric servers. Without this, servers in offline mode would assign generic UUIDs and break skin rendering, making it impossible to run a cohesive network with proper player profiles. Trampoline restores that missing link, allowing you to enjoy the full benefits of BungeeCord without sacrificing player identity.
Why Use Trampoline for Your Minecraft Server?
BungeeCord networks typically require backend servers to run in offline mode, which disables the standard Mojang authentication. While this allows the proxy to manage connections, it also means the server cannot verify player UUIDs or fetch skins. The result? Players appear as "Steve" or "Alex" with generic offline UUIDs, breaking any plugins or features that rely on unique player data. Trampoline fixes this by implementing IP forwarding, a technique that lets the proxy securely transmit the real player information to the Fabric server. Once installed, the mod automatically configures the server into offline mode to work with BungeeCord, but it also intercepts the forwarded data to restore authentic UUIDs and skins. This means your network can have seamless teleportation between servers while maintaining accurate player profiles, permissions, and cosmetic customizations.
How to Install Trampoline
Installing Trampoline is straightforward, but there are a few critical steps to ensure it works correctly. First, you must have Fabric API installed on your server, as Trampoline depends on it to function. Without Fabric API, the mod will fail to load. Once that prerequisite is met, follow these steps:
- Download Trampoline from a trusted mod repository like CurseForge or Modrinth. Look for the latest version compatible with your Minecraft server release.
- Place the downloaded .jar file into your server's
modsfolder. - Restart your server. Trampoline will automatically detect the BungeeCord environment and configure the server into offline mode while enabling IP forwarding.
It is crucial to secure your network properly. Before installing Trampoline, make sure players cannot join your backend servers directly and bypass the BungeeCord proxy. Follow a firewall guide (such as the one available on SpigotMC) to restrict access, otherwise malicious users could impersonate others. Once your firewall rules are in place, simply drop the mod into the mods folder and restart. The mod handles the rest, so you can focus on building your network.
Compatibility and Requirements
Trampoline is built for the Fabric mod loader and supports modern Minecraft versions, including 1.19, 1.20, and the latest 1.21 releases. Always check the mod page for the exact version compatibility, as updates are frequent. The only hard requirement is Fabric API, which must be installed alongside Trampoline. If you manage your server through the foxygame.net launcher, you can install Trampoline with a single click from its add-on catalog, and the launcher will automatically match the correct version for your server setup. This eliminates the guesswork and ensures that Fabric API is also present if needed. The launcher even handles auto-updates for Trampoline, so your network stays secure and compatible without manual intervention.
Download Trampoline for Minecraft
You can download Trampoline from popular mod hosting platforms. Search for "Trampoline for Minecraft" on CurseForge or Modrinth to find the official release. Always verify that you are getting the mod from a legitimate source to avoid corrupted files. The download page will list all available versions, so pick the one that matches your server's Minecraft version and Fabric loader. If you are new to server modding, consider using a launcher that simplifies the process—many server owners appreciate how the foxygame.net launcher integrates Trampoline directly into its one-click install system, making setup effortless.
Final Thoughts
Trampoline is an essential tool for any server administrator running a BungeeCord network with Fabric backend servers. It solves the offline mode identity crisis cleanly and requires minimal configuration. By restoring real UUIDs and skins, it ensures that your players enjoy a consistent experience across all connected servers. Whether you are building a minigame hub, a survival network, or a creative community, Trampoline keeps player data intact. Just remember to secure your firewall, install Fabric API, and drop the mod into your server. With Trampoline, your BungeeCord network will finally feel whole.
