出门在外想随时连家里的 NAS、调一下台式机里的 Ollama，或者开 Moonlight 串流，最烦这几件事： 没有公网 IPv4、大内网 NAT 环境复杂、开路由器端口映射又怕天天被全网脚本扫爆。 试试 Rust 写的轻量私有组网工具 Lantunnel，体验非常丝滑：

彻底告别公网暴露：所有设备都是主动向外握手建联，路由器不需要开任何入站规则和映射，家里的机器老老实实呆在 NAT 后面隐身。

QUIC 直连优先：设备之间优先尝试 UDP 打洞直连，跑满家里上行带宽；打不通时自动切加密中继，中继只负责搬运密文，中间人碰不到明文。

本地极简接入：不想装虚拟网卡接管全机路由？客户端在本地监听 SOCKS5（127.0.0.1:1080）即可按需接入，也支持导出整个内网网段直接访问全家设备。

零门槛试水：http://lantunnel.app 提供永久免费 Tunnel，直连流量不限量，每月附赠 5GB 加密中继应急；想要跑满私有带宽也能单命令自建 Gateway。
