# 项目概览

## 目标
* 将域名 **gmcc.net** 及其所有子域通过 **OSS（Open Source Switch）** 进行完整路由，而不依赖任何代理或中间软件。

## 关键实现
1. **DNS 监听**：在 `127.0.0.54:53` 上安装 UDP/TCP 监听，将 `gmcc.net` 与 `*.gmcc.net` 的查询通过 NRPT（Network‑Based Routing Policy）重定向到此监听。
2. **/32 路由**：对每个返回的 IPv4 地址，动态在 OS 上创建 `/32` 路由，使用 OSS‑/32 保护，并对实际下一跳进行验证，只返回 A 记录。
3. **IPv6 和 AAAA**：抑制所有 IPv6、HTTPS、SVCB/HTTPS 等指示，拒绝 IPv6 建议。
4. **路由守卫（Guard）**：通过隐藏的 SYSTEM 计划任务完成默认路由与防火墙规则的自动校正。
5. **菜单与状态整合**：在系统工具中增设 “OSS Routing” 菜单，实时显示路由状态并允许启用/禁用。

## 已完成项目
- 发行版本 `4d5d97a…` 完成 PowerShell/NET 服务的部署与测试。
- 单元与集成测试全部通过，覆盖 DNS 解析、路由创建、NRPT 与防火墙规则。
- 处理 188.15/24 / 188.25/24 等地址块，并支持 `/24` 与 `/16` 前缀切换。
- 兼容 Windows 10/11，保持 OS 默认路由、Mihomo/Clash 等代理不变。
