Proxy Protocol support for Fabric servers
Does not follow a specific thematic focus apart from vanilla Minecraft.
Used for mods with little to no gameplay elements.
Includes tools and features for server management.
Provides a framework or library for other mods to use.
Forge is a popular mod loader for versions 1.1+ of Minecraft.
Fabric is a mod loader for versions 1.14+ of Minecraft, particularly popular for client side and optimization mods.
Quilt is a fork of the Fabric mod loader. Many Fabric mods are compatible with Quilt and vice versa.

Description
Proxy Protocol Support
Proxy Protocol Support is a Fabric and Quilt mod which adds support for Proxy Protocol (HAProxy) for your Minecraft server. It allows to accept both proxied and direct connections simultaneously.
For example you can use TCPShield or other software (Nginx, FRP) to forward traffic, and hide your server's IP address. Without Proxy Protocol, your console will only show the proxy's IP address. By reading the Proxy Protocol packet, this mod makes showing the player's real IP address possible.
This is a Server-Side only mod; it does nothing when installed on a client.
Supports Minecraft versions 1.14-1.21.10 and probably later (untested).
Secure Hybrid Mode
This mod allows your Minecraft server to simultaneously accept connections from a trusted proxy (using the PROXY protocol) and from trusted direct-access IPs. This is perfect for setups where you want to hide your server's IP behind a proxy, while still allowing admins or local players to connect directly.
The mod operates on a secure "Default Deny" principle. If an incoming connection's IP address is not explicitly whitelisted in one of the lists below, it will be rejected. This prevents unauthorized users from bypassing your proxy and connecting directly to your server's real IP address.
Configuration
Configuration is handled in config/proxy_protocol_support.json.
enableProxyProtocol
Set to true to enable the mod's functionality.
- Default:
true
proxyServerIPs
A list of IP addresses that are your trusted proxy servers. Connections from these IPs must send a PROXY Protocol header.
- Default:
["127.0.0.1"]
directAccessIPs
A list of IPs or CIDR ranges that are allowed to connect directly without a PROXY Protocol header. This is ideal for admins, local network players, and server-side tools.
- Default:
["127.0.0.1", "192.168.0.0/16"]
whitelistTCPShieldServers
When true, the mod automatically fetches TCPShield's official proxy IPs and adds them to the trusted proxyServerIPs list.
- Default:
false
Example Scenarios
Scenario 1: Server behind FRP on the same machine
You run frpc on the same machine as the Minecraft server. Players from the internet connect through the proxy. You want to connect directly from your gaming PC on the same LAN (192.168.1.100).
proxyServerIPs = ["127.0.0.1"]
directAccessIPs = ["127.0.0.1", "192.168.1.100"]Scenario 2: Server protected by a remote proxy service
Your server is at home, and you use a VPS with the IP 203.0.113.10 as a proxy. You want your entire home network (192.168.0.0/24) to have direct access.
proxyServerIPs = ["203.0.113.10"]
directAccessIPs = ["127.0.0.1", "192.168.0.0/24"]Scenario 3: Maximum Security (Proxy Only)
You only want to allow connections through your proxies and nothing else (not even from the local machine).
proxyServerIPs = ["1.2.3.4", "5.6.7.8"] # Your proxy IPs
directAccessIPs = [] # Leave emptyLooking for Minecraft server? Visit BedrockHost.pl
