CoolGateway

Acts like a local Proxy Plugin for your Minecraft Home Server:

1. optimizes Bandwidth usage on your server (and your ISP) but sending much less tcp packets (like a compression), saving many TCP packet header bytes;
2. point above increases a bit the latency on fast connections (~1ms) but helps reducing for slower connection users, keeping them more stable;
3. gives some protection against external unwanted connections;
4. blocks spam connections;
5. provides connection auditing;
6. TCPShield complient, but if you have that you don't need this plugin.
7. Only usable for home servers, without other protections like the one above, Velocity proxies or server hosts like Aternos,...

To setup simply configure:

1. Change Minecraft server Listen port (usually from 25565 to something different not exposed to internet)
2. Set ListenPort: the port visible on your internet (default 25565)
3. Set MinecraftListen: your internal minecraft port (port set at point 1)
4. Set ProtectListen: true to make connection verification (spam, some malformed messages,...). Default true

Compatibility:

• All known Hardware and OS.
• All Minecraft Versions from 1.20+, but recommended 1.21.1+
• Bukkit, Spigot and Paper based servers
