|
||
|
||
## 1. 网络拓扑
|
||
|
||
```
|
||
光猫 (拨号, Dynamic IP)
|
||
│
|
||
▼ WAN (eth0, DHCP)
|
||
iStoreOS (192.168.68.63) ← 主网关
|
||
├── dnsmasq (:53) → 内网 DNS + 转发到 OpenClash
|
||
├── OpenClash / mihomo (:7874) → fake-ip + TUN → 翻墙回国 + 广告拦截
|
||
├── 端口映射 (2200, 443, 51888)
|
||
├── DHCP (网关=.63, DNS=.63)
|
||
│
|
||
▼ LAN (eth1/eth2/eth3)
|
||
├── Deco BE65 (AP) → WiFi → 手机/平板/笔记本
|
||
└── 交换机 (2楼) → PVE + NAS
|
||
```
|
||
|
||
### DNS 解析链路
|
||
|
||
```
|
||
设备 → dnsmasq (:53)
|
||
├─ 内网域名 (*.colacoder.com, *.k8s.home) → 直接返回真实 IP
|
||
└─ 外部域名 → OpenClash (:7874, fake-ip)
|
||
├─ fake-ip-filter 匹配 → 返回真实 IP
|
||
├─ 广告域名 → REJECT
|
||
├─ 国内域名 → fake-ip → VLESS 代理回国
|
||
└─ 海外域名 → fake-ip → 直连
|
||
```
|
||
|
||
---
|
||
|
||
## 2. OpenClash 配置
|
||
|
||
### LuCI 后台设置
|
||
|
||
| 设置 | 值 |
|
||
|------|-----|
|
||
| 运行模式 | Fake-IP (TUN) |
|
||
| 代理模式 | Rule 策略代理 |
|
||
| 区域绕过 | **停用** |
|
||
| 域名嗅探 | 启用 |
|
||
| DNS 代理 | 停用 |
|
||
| 本地 DNS 劫持 | 使用 Dnsmasq 转发 |
|
||
|
||
### 覆写设置 → DNS
|
||
|
||
| 设置 | 值 |
|
||
|------|-----|
|
||
| Default-NameServer | `8.8.8.8`, `1.1.1.1` |
|
||
| NameServer | `8.8.8.8`, `1.1.1.1` |
|
||
| Fallback | `dns.google`, `cloudflare-dns.com` |
|
||
|
||
> **重要：** NameServer 必须用海外 DNS，不能用国内 DNS（114、119、223 等），
|
||
> 否则会产生 DNS 环路（国内 DNS IP 匹配 GEOIP,CN → 走代理 → 代理需要 DNS → 死循环）。
|
||
|
||
### 配置文件
|
||
|
||
- 源配置：`/etc/openclash/config/vless-reality.yaml`
|
||
- 运行配置：`/etc/openclash/vless-reality.yaml`（自动生成，勿手动改）
|
||
- API Secret：`Dc7jZkmO`
|
||
- Dashboard：http://192.168.68.63:9090
|
||
|
||
### 自定义文件（持久化，不被覆盖）
|
||
|
||
| 文件 | 用途 |
|
||
|------|------|
|
||
| `/etc/openclash/custom/openclash_custom_hosts.list` | 内网 DNS 映射 |
|
||
| `/etc/openclash/custom/openclash_custom_fake_filter.list` | fake-ip 排除域名 |
|
||
|
||
---
|
||
|
||
## 3. 内网 DNS
|
||
|
||
双重保障：dnsmasq 和 OpenClash hosts 都配了内网记录。
|
||
|
||
### dnsmasq 配置
|
||
|
||
文件：`/etc/dnsmasq.d/internal-dns.conf`
|
||
|
||
```
|
||
address=/k8s.home/192.168.68.70
|
||
address=/nas.colacoder.com/192.168.68.70
|
||
address=/pve.colacoder.com/192.168.68.70
|
||
address=/npm.colacoder.com/192.168.68.70
|
||
address=/router.colacoder.com/192.168.68.63
|
||
address=/adguard.colacoder.com/192.168.68.63
|
||
address=/claw.colacoder.com/192.168.68.70
|
||
address=/openvas.colacoder.com/192.168.68.70
|
||
address=/invest-api.k8s.home/192.168.68.240
|
||
```
|
||
|
||
### OpenClash 自定义 hosts
|
||
|
||
文件：`/etc/openclash/custom/openclash_custom_hosts.list`
|
||
|
||
```yaml
|
||
nas.colacoder.com: 192.168.68.70
|
||
pve.colacoder.com: 192.168.68.70
|
||
npm.colacoder.com: 192.168.68.70
|
||
router.colacoder.com: 192.168.68.63
|
||
adguard.colacoder.com: 192.168.68.63
|
||
claw.colacoder.com: 192.168.68.70
|
||
openvas.colacoder.com: 192.168.68.70
|
||
invest-api.k8s.home: 192.168.68.240
|
||
```
|
||
|
||
### fake-ip 排除列表
|
||
|
||
文件：`/etc/openclash/custom/openclash_custom_fake_filter.list`
|
||
|
||
```
|
||
*.colacoder.com
|
||
+.colacoder.com
|
||
*.k8s.home
|
||
+.k8s.home
|
||
*.lan
|
||
*.local
|
||
*.localdomain
|
||
*.home.arpa
|
||
```
|
||
|
||
---
|
||
|
||
## 4. 端口映射
|
||
|
||
| 规则名 | 外部端口 | 目标 |
|
||
|--------|---------|------|
|
||
| NAS-SSH-2200 | 2200 | 192.168.68.70:2200 |
|
||
| NAS-HTTPS-443 | 443 | 192.168.68.70:443 |
|
||
| Device-51888 | 51888 | 192.168.68.107:51888 |
|
||
|
||
---
|
||
|
||
## 5. DHCP 静态绑定（19 台设备）
|
||
|
||
| 名称 | IP | MAC |

||
## 6. 踩坑记录
|
||
|
||
### DNS 环路（最关键）
|
||
|
||
OpenClash 的 nameserver 不能用国内 DNS（114.114.114.114、119.29.29.29 等），
|
||
因为这些 IP 匹配 GEOIP,CN 规则 → 走代理 → 代理需要 DNS → 死循环。
|
||
**必须用海外 DNS（8.8.8.8、1.1.1.1）。**
|
||
|
||
### OpenClash 配置覆盖
|
||
|
||
OpenClash 每次重启都会从源配置重新生成运行配置。
|
||
自定义 hosts 和 fake-ip-filter 必须放在 `/etc/openclash/custom/` 目录下的专用文件里。
|
||
直接改 yaml 文件会被覆盖。
|
||
DNS 相关设置必须在 LuCI 覆写设置里改，不能改 yaml。
|
||
|
||
### 区域绕过必须停用
|
||
|
||
翻墙回国场景下，"大陆"和"海外"绕过都不合适，必须选"停用"，
|
||
让配置文件里的分流规则来决定。
|
||

||
|
||
## 7. 紧急恢复
|
||
|
||
```bash
|
||
SSH_AUTH_SOCK="$HOME/Library/Group Containers/2BUA8C4S2C.com.1password/t/agent.sock" ssh root@192.168.68.63
|
||
|
||
# 停止 OpenClash（恢复直连上网）
|
||
/etc/init.d/openclash stop
|
||
|
||
# 如果 DNS 也断了，临时用 8.8.8.8
|
||
echo "nameserver 8.8.8.8" > /etc/resolv.conf
|
||
```
|
||
|
||
---
|
||
|
||
## 8. 更新维护
|
||
|
||
```bash
|
||
# 更新 mihomo 内核
|
||
cd /tmp
|
||
curl -L -o mihomo.gz "https://github.com/MetaCubeX/mihomo/releases/latest/download/mihomo-linux-arm64.gz"
|
||
gunzip -f mihomo.gz && chmod +x mihomo
|
||
mv mihomo /etc/openclash/core/clash_meta
|
||
/etc/init.d/openclash restart
|
||
|
||
# 更新 OpenClash 插件
|
||
opkg install /tmp/luci-app-openclash_*.ipk
|
||
```
