让 Minecraft 玩家和服务器之间走 P2P 直连，游戏流量不经过中转节点。类似 HMCL、PCL 启动器自带的联机功能，只不过面向的是有正经服务端的场景。
国内很多 MC 服务器跑在“家里云”上——家里宽带没有公网 IP，服主会通过樱花 frp 之类的第三方端口转发让玩家连进来。作者不喜欢让游戏流量一直经过中转节点，于是做了 Netherway。
Netherway 让这类服务器也能 P2P 直连：玩家和服务器打洞成功后，游戏流量直接走 UDP 互连，第三方只负责最初的信令交换，不再转发游戏数据。
从 GitHub Releases 下载与你的 Minecraft 版本和平台匹配的 Netherway：
- Forge / Fabric 版：客户端和服务端分别放入对应实例的
mods/文件夹。 - Bukkit 版：放入服务端的
plugins/文件夹。
目前提供 Forge 1.7.10、Forge 1.12.2、Forge/Fabric 1.16.5、1.18.2、1.20.1 以及 Bukkit（Spigot/Paper 1.13+，仅服务端）版本。安装、默认配置、可选功能和故障排查请阅读完整中文文档。
Netherway establishes a peer-to-peer connection between Minecraft players and servers, so gameplay traffic no longer passes through a relay. It provides an experience similar to the multiplayer features built into launchers such as HMCL and PCL, but is designed for dedicated servers.
Many Minecraft servers run behind residential connections without a public IP address, so their owners use third-party port-forwarding services to make them reachable. The author does not like keeping gameplay traffic on a relay path, which is why Netherway exists.
Once Netherway successfully performs NAT traversal, gameplay traffic flows directly between the player and the server over UDP. The third-party service is used only for the initial signaling exchange and no longer carries gameplay data.
Download the Netherway build matching your Minecraft version and platform from GitHub Releases:
- Forge / Fabric: place the JAR in the
mods/folder of both the client and server instances. - Bukkit: place the JAR in the server's
plugins/folder.
Builds are available for Forge 1.7.10, Forge 1.12.2, Forge/Fabric 1.16.5, 1.18.2 and 1.20.1, and Bukkit (Spigot/Paper 1.13+, server only). See the complete English documentation for installation, default configuration, optional features, and troubleshooting.
