Adds support for Velocity's Modern Forwarding in NeoForge. Velocity's Modern Forwarding protocol transfer user data directly from the proxy to the server, which acts as a second layer of protection against bad actors on top of your firewall. For more detailed information, see the official documentation here.
This implementation strives for consistency with Paper's implementation of modern forwarding. This helps with compatibility and keeps the code simple.
For any questions, please ask in the #velocity-support channel on my discord.
First, you will need a Velocity proxy set up. I assume if you are already looking at this mod, you already have this set up. If not, for detailed steps on setting up a proxy, see the official documentation here.
Once you are at the point where you want to connect your NeoForge server to the proxy, install the mod of the
appropriate version to your server. After that, simply copy your proxy's forwarding.secret file into your NeoForge
server's directory. Of course, make sure your server is in offline mode (online-mode=false in server.properties).
Launch your server and you are good to go!
If you are having troubles connecting to your server and Velocity is giving a packet decoding error, add the following argument to your proxy's startup script:
-Dvelocity.packet-decode-logging=true
This will make Velocity give more information regarding packet decoding errors.
