# Be Quiet Negotiator<\/p>\n
Be Quiet Negotiator is a lightweight, client-side-only NeoForge mod that lets modded clients connect to vanilla or
\nminimally modded servers (such as Fabric servers with only server-side mods) without triggering NeoForge\u2019s
\nstrict network negotiation process.<\/p>\n
## How it works<\/p>\n
Normally, NeoForge enforces a handshake protocol to ensure both client and server agree on modded payloads and
\ncapabilities. This mod quietly suppresses that negotiation when connecting to servers that don\u2019t speak NeoForge,
\nallowing the connection to go through cleanly without disconnects or errors \u2014 hence, it \u201cnegotiates\u201d by staying silent.<\/p>\n
In addition, other errors that may occur during the connection process, such as packet decoding errors
\nor unexpected packet sizes, are also ignored, allowing the client to connect without issues.<\/p>\n
Specifically, Be Quiet Negotiator uses Mixins to patch the NeoForge client code, specifically targeting any annoying
\nmethods which produce errors or disconnects when connecting to servers that do not support NeoForge.<\/p>\n
Furthermore, all patches are configurable, allowing users to enable or disable specific patches as needed.<\/p>\n
## Use cases<\/p>\n
This mod is ideal for:
\n1. Players using NeoForge clients who want to join vanilla servers, preventing disconnects caused by missing network negotiation responses.
\n2. Players connecting through hybrid or proxy networks, where the entrypoint is a vanilla or non-NeoForge server, avoiding failed handshakes when the client expects NeoForge.
\n3. Modpack developers or testers using full-stack NeoForge mods client-side, who want to connect to unmodded or differently modded servers without having to disable mods each time.
\n4. Players attempting to join servers without NeoForge, while still having mods installed that expect a modded server-side (e.g., worldgen, item, or GUI mods with networking).
\n5. LAN or casual multiplayer setups, where only the client is running NeoForge with full-feature mods, and the server is unmodded or running a different mod loader.<\/p>\n
## Making a production-ready proxy network?<\/p>\n
Do not use this mod! You will likely run into issues with mod compatibility, as Be Quiet Negotiator just suppresses errors
\nand does not magically make incompatible mods work.<\/p>\n
Instead of using a traditional proxy to route connections to backend servers, I recommend giving each NeoForge server
\nits own public IP address \/ domain.<\/p>\n
If you don’t have enough IP addresses, you can use a reverse proxy like
\nGate Lite Mode or my own mc-router
\nto route connections based on the Handshake packet’s Server Address field.<\/p>\n
To transfer players between servers, use the vanilla `\/transfer` command introduced in Minecraft 1.20.5, or install the
\nServer Redirect mod.<\/p>\n
## Included Patches (since v1.0.1)<\/p>\n
– `bypassNegotiationErrors` – Allows the client to connect to servers that do not support NeoForge by ignoring negotiation errors.
\n– `bypassCustomFeatureFlags` – Ignores custom feature flags when connecting to a server, allowing the client to connect without issues.
\n– `ignorePacketDecodingErrors` – Ignores packet decoding errors when connecting to a server, allowing the client to connect without issues.
\n– `ignorePacketHandlerErrors` – Ignores client-side packet handling errors when connecting to a server, allowing the client to connect without issues.<\/p>\n
## Important notes<\/p>\n
### Connection Safety<\/p>\n
Be Quiet Negotiator is safe by design: it only activates when the server is identified as non-NeoForge, leaving
\nnormal modded-to-modded connections completely untouched. Configuration is simple and toggleable, giving users fine
\ncontrol over when quiet negotiation is allowed.<\/p>\n
### Mod Compatibility<\/p>\n
Some mods may depend on successful negotiation or expect server-side support for certain features. In these cases, functionality may break silently or result in confusing behaviour.<\/p>\n
Use caution, and avoid placing or interacting with modded blocks, items, or GUIs on servers that aren\u2019t running NeoForge. **This mod enables connection compatibility, but it cannot make incompatible mods magically work.**<\/p>\n
