What is Floodgate and why do I need it with GeyserMC?

Floodgate is a plugin that allows Bedrock players to join a Java server without needing a Java edition account. Without Floodgate, Bedrock players would need to authenticate through a Java account. Floodgate prefixes Bedrock players' usernames with a dot (.) to distinguish them from Java players and handles authentication separately.

Which devices can connect to a Java server with GeyserMC?

GeyserMC supports all Minecraft Bedrock Edition clients: Android (mobile), iOS (iPhone/iPad), Xbox One, Xbox Series X/S, PlayStation 4, PlayStation 5, Nintendo Switch, Windows 10, and Windows 11 (Bedrock edition). PC players using Java Edition connect normally without GeyserMC.

Can Bedrock players use Java-only plugins on a GeyserMC server?

Bedrock players can interact with the outcomes of Java-only plugins (items, effects, commands) but cannot use client-side Java features. Most gameplay plugins (economy, protection, permissions) work fully for Bedrock players. Some UI plugins that use Java-specific inventory layouts may have limited functionality for Bedrock clients due to Bedrock's different UI system.

Q: What port does GeyserMC use?

GeyserMC uses UDP port 19132 by default — the same port as Minecraft Bedrock Edition. Java Edition uses TCP port 25565. Both ports need to be open on your server's firewall. Azion Cloud Minecraft plans automatically configure both ports.

GeyserMC lets Mobile (Android and iOS), Xbox, PlayStation, Nintendo Switch, and Windows Bedrock players join the same Java Edition Minecraft server as PC Java players — with no client-side modifications required. This guide explains how GeyserMC and Floodgate work together, how to set them up manually, and what Indian server owners need to know about crossplay.

How GeyserMC Crossplay Works

Java Edition and Bedrock Edition use completely different network protocols. They cannot communicate with each other natively — a Bedrock client cannot connect to a Java server and vice versa.

GeyserMC solves this as a protocol translation proxy. When a Bedrock player connects to your server's IP, they're actually connecting to the GeyserMC proxy running on your server. GeyserMC receives Bedrock packets, translates them to Java packets, and sends them to the actual Minecraft Java server — and does the same in reverse for outgoing packets.

From the perspective of your Java server: it only ever sees Java Edition clients. GeyserMC handles all the translation transparently.

What is Floodgate?

Without Floodgate, Bedrock players connecting through GeyserMC would still need to authenticate with a Java Edition account (bought separately). Floodgate removes this requirement.

Floodgate is a plugin that works alongside GeyserMC to allow Bedrock players to authenticate using their Xbox/Microsoft account (Bedrock account) instead of requiring a Java account. Bedrock players' usernames are prefixed with a period (.) to distinguish them from Java players in the server's player list and permission systems.

On Azion Cloud: GeyserMC and Floodgate are pre-installed and pre-configured on all Minecraft plans. Bedrock players can connect immediately on port 19132 — no manual setup required. The key.pem sharing between Floodgate and GeyserMC is handled automatically.

Supported Bedrock Devices

Platform	Bedrock Version	GeyserMC Support	Connection IP Format
Android (Mobile)	Bedrock 1.20+	Full	IP:19132 (external server)
iOS (iPhone/iPad)	Bedrock 1.20+	Full	IP:19132 (external server)
Xbox One / Series X/S	Bedrock 1.20+	Full	Requires BedrockTogether workaround
PlayStation 4 / 5	Bedrock 1.20+	Full	Requires BedrockTogether workaround
Nintendo Switch	Bedrock 1.20+	Full	Requires BedrockTogether workaround
Windows 10/11 (Bedrock)	Bedrock 1.20+	Full	IP:19132 direct connection
Windows 10/11 (Java)	Java 1.20+	Native	IP:25565 (standard)

Console players (Xbox, PlayStation, Switch) cannot add external servers directly from the server list — they require the BedrockTogether or Bedrock-Lan-Proxy workaround to make the server appear as a LAN game. This is a Minecraft console limitation, not a GeyserMC limitation.

Manual Setup Guide (Paper/Purpur Servers)

Download GeyserMC and Floodgate

Go to geysermc.org/download. Download GeyserMC-Spigot.jar (for Paper/Purpur/Spigot) and Floodgate-Spigot.jar. Always use the latest build.

Install both plugins

Upload both JAR files to your server's /plugins/ directory via SFTP or the Pterodactyl file manager. Do not start the server yet.

Start the server once to generate configs

Start the server. GeyserMC creates /plugins/Geyser-Spigot/config.yml and Floodgate creates /plugins/floodgate/config.yml and a key.pem file. Stop the server.

Copy the Floodgate key to GeyserMC

Copy /plugins/floodgate/key.pem to /plugins/Geyser-Spigot/key.pem. This allows GeyserMC to verify Floodgate's authentication tokens.

Configure the Bedrock port

In /plugins/Geyser-Spigot/config.yml, confirm bedrock.port: 19132. Open UDP port 19132 in your server's firewall alongside TCP 25565.

Restart and test

Restart the server. Java players connect to yourip:25565 as normal. Bedrock/Mobile players connect to yourip:19132 from the "External Servers" option in Minecraft Bedrock.

Key GeyserMC Configuration Options

# /plugins/Geyser-Spigot/config.yml (key settings)
bedrock:
  port: 19132          # UDP port for Bedrock connections
  motd1: "My Server"   # Bedrock server list title
  motd2: "GeyserMC"    # Bedrock server list subtitle

remote:
  address: auto        # connects to the Java server automatically
  port: 25565

floodgate-key-file: key.pem   # path to Floodgate's key (required)

# Username prefix for Bedrock players (visible in /list, permissions, etc.)
# Default: "." (dot) — e.g., ".Abhijot" for Bedrock player "Abhijot"

Plugin Compatibility with Bedrock Players

Plugin Type	Works for Bedrock?	Notes
Economy (Vault, EssentialsX)	Full	Commands, balances, shops work normally
Permissions (LuckPerms)	Full	Bedrock username includes dot prefix
Protection (WorldGuard)	Full	Flags and regions apply to Bedrock players
Anti-Cheat	Partial	Some Java-specific movement checks need whitelist for Bedrock
Custom Inventory GUIs	Partial	Standard chests work; book GUIs may not render on Bedrock
Chat Plugins	Full	Messages appear correctly; Bedrock has different chat UI
Minigame Plugins	Partial	Depends on plugin; most work, complex UI may break

Anti-cheat configuration: Popular anti-cheat plugins (Grim, Vulcan, Matrix) may flag Bedrock players for movement violations because Bedrock's physics differ from Java. Add your server's GeyserMC connection IP (127.0.0.1 in plugin mode) to the anti-cheat whitelist, or enable the GeyserMC-specific anti-cheat compatibility settings in the plugin.

Why GeyserMC Matters for Indian Minecraft Servers

In India, a significant portion of Minecraft's player base plays on Bedrock Edition via Mobile (Android/iOS) — either because mobile is their primary gaming platform or because they use the free trial version. Without GeyserMC, these players cannot join Java servers.

For Indian Minecraft server owners, GeyserMC crossplay can double the accessible player pool by including mobile players who would otherwise be excluded. Public Indian SMP servers that enable GeyserMC consistently report higher player counts than Java-only equivalents.

FAQ

What is GeyserMC?

GeyserMC is an open-source proxy plugin that translates the Minecraft Bedrock Edition network protocol into Java Edition protocol. This allows Bedrock clients — Mobile, Xbox, PlayStation, Nintendo Switch, Windows Bedrock — to connect to a Java Edition Minecraft server without any modification to either the Java server or the Bedrock client.

Do Bedrock players need to buy Java Edition to join with GeyserMC?

No. With Floodgate installed alongside GeyserMC, Bedrock players authenticate using their Xbox/Microsoft account (Bedrock account). They do not need to own or purchase Java Edition. This is the key advantage of Floodgate — it removes the Java account requirement for Bedrock players.

Can Mobile players play on a Java Minecraft server in India?

Yes, with GeyserMC and Floodgate installed on the Java server. Android and iOS players open Minecraft Bedrock Edition, go to Servers, then Other Servers, and add the server's IP and port 19132. They can then join and play on the Java server alongside PC Java players, with full access to the world, economy, and most plugins.

Does GeyserMC affect server performance or TPS?

GeyserMC adds a small amount of CPU overhead for protocol translation — typically 1-3% additional CPU usage per concurrent Bedrock player. On modern hardware (Ryzen 9, Intel Xeon Platinum), this is negligible and does not cause measurable TPS drops for most Indian server configurations.

What port does GeyserMC use?

GeyserMC uses UDP port 19132 by default — the standard Minecraft Bedrock Edition port. Java Edition uses TCP port 25565. Both ports must be open on your server's firewall. On Azion Cloud, both ports are automatically configured and open for all Minecraft plans.
