# VPS 流量转发配置
|
||
|
||
基于 **Xray + Nginx SNI 分流 + Mihomo TUN 透明代理 + WireGuard**,实现:
|
||
内网服务反向代理、多 VPS 链路中转、BT 透明代理、Minecraft UDP 转发。
|
||
|

|
||
|
||
## 设备
|
||
|
||
| 设备 | IP / 域名 | 角色 |
|
||
|---|---|---|
|
||
| **北京 VPS** | `salmonstill.cn` / `49.232.242.90` | 公网入口,Nginx + Xray + socat + WireGuard |
|
||
| **搬瓦工 VPS** | `173.242.118.60` | 代理出口,Xray Reality 入站(客户端直连) |
|
||
| **旁路由** | `192.168.1.199` / WG `10.0.0.2` | 内网核心,Xray bridge + Mihomo 代理 |
|
||
| **NAS** | `192.168.1.188` | 绿联云 UGOS,思源笔记等服务 |
|
||
| **qBittorrent** | `192.168.1.200` (macvlan) | PT 下载,独立 IP |

|
||
|
||
## Nginx SNI 分流 (`beijing-vps-stream.conf`)
|
||
|
||
监听 `:443`,按 SNI 将流量分发到不同后端:
|
||
|
||
| SNI | 后端 | 端口 | 用途 |
|
||
|---|---|---|---|
|
||
| `www.apple.com` | Xray interconn | :9443 | 反向代理隧道 |
|
||
| `www.microsoft.com` | Xray mihomo_in | :9444 | Mihomo 客户端 → 搬瓦工出口 |
|
||
| `news.apple.com` | Xray proxy_from_lan | :9445 | 北京直连代理 |
|
||
| `drive.salmonstill.cn` | NAS | :38653 | 绿联云直接转发 |
|
||
| 默认 | NPM | :8443 | Nginx Proxy Manager |
|
||
|
||
搬瓦工 VPS(部署 `东京-vps-stream.conf` + `tokyo-vps-config.json`):`www.microsoft.com` → Xray :9443,默认 → NPM。
|
||
|

|
||
|
||
## Xray 核心
|
||
|
||
### 北京 VPS (`xray-北京vps-config.json`)
|
||
|
||
**Reality 入站** — 共享 privateKey `GGT9LfN_...`,由 Nginx SNI 转发:

|
||
|---|---|---|---|
|
||
| `proxy_in` | 10809 | mixed | SOCKS5/HTTP 代理 → 搬瓦工出口 |
|
||
| `socks-dynamic` | 38658 | SOCKS5 (password) | 动态 LAN 端口访问 |
|
||
|
||
**出站**:`direct`(freedom 直连)、`to_tokyo`(VLESS+Reality → `173.242.118.60:443`)
|
||
|
||
**路由**:所有 `external_*` + `interconn` + `socks-dynamic` → `portal`(反向隧道);`mihomo_in` + `proxy_in` → `to_tokyo`;`proxy_from_lan` → `direct`
|
||
|
||
### 旁路由 (`xray-旁路由-config.json`)
|
||
|
||
**Bridge 入站**:与北京 VPS 的 Portal 建立永久反向隧道。
|
||
|
||
**出站**(14 个):
|
||
|
||
| Tag | 目标 | 用途 |
|
||

|
||
| `direct` | freedom | 直连 |
|
||
|
||
**路由规则**(bridge 入站按端口匹配):

|
||
- 38659 → `to_spark_ssh`(Spark SSH 远程)
|
||
- 38660 → `to_spark_rdp`(Spark xRDP 桌面远程)
|
||
- 38662 → `to_spark_38662`
|
||
- 默认(catch-all)→ **`direct`**(不匹配端口规则的动态请求直连目标)
|
||
- `socks-lan` 入站 → `to_beijing_direct`
|
||
|
||
> 所有显式端口规则优先于 catch-all,现有端口转发不受影响。
|
||
|
||
### 搬瓦工 VPS / 洛杉矶 (`tokyo-vps-config.json`)
|
||
|
||
极简:VLESS+Reality 入站 `:9443`(SNI=www.microsoft.com),freedom 出站。
|
||
所有客户端(Spark、旁路由、macOS)直连此服务器,不再经北京 VPS 中转。
|
||
|
||
---
|
||
|
||
## Mihomo
|
||
|
||
### 旁路由 (`旁路由的mihomo config.yaml`)
|
||
|
||
**纯代理模式** — 无内核级劫持,提供多端口代理服务供客户端手动指定:
|
||
|
||
| 端口 | 类型 | 路由 | 用途 |
|
||
|---|---|---|---|
|
||
| `7890` | mixed | 按规则分流 | 本地服务默认代理 |
|
||
| `7891` | mixed | 全部走 US-Direct | 全局国外代理 |
|
||
| `7892` | mixed | 全部直连 | 全局国内直连 |
|
||
|
||
配合 **fake-ip DNS**(`enhanced-mode: fake-ip`),DNS 请求返回 `198.18.x.x` 假 IP,强制流量进入代理路由。
|
||
|
||
**代理节点**:
|
||
- `US-Direct` — VLESS+Reality → `173.242.118.60:443`(默认国外出口,客户端直连搬瓦工)
|
||
|
||
**关键策略组**:
|
||
- 国外 → `[US-Direct, 直连]`
|
||
|
||
**防死循环 IP**:`49.232.242.90`(北京 VPS)、`173.242.118.60`(搬瓦工 VPS)强制直连。
|
||
|
||
**额外监听器**:`:7891`(全局→US-Direct)、`:7892`(强制直连)
|
||
|
||
### macOS (`非tun模式的主机mihomo config.yaml`)
|
||
|
||
结构与旁路由一致,无 TUN,监听器 `:7890` + `:7891` + `:7892`。
|
||
|
||
**重启**(launchctl 管理):
|
||
```bash
|
||
launchctl unload ~/Library/LaunchAgents/com.mihomo.proxy.plist
|
||
launchctl load ~/Library/LaunchAgents/com.mihomo.proxy.plist
|
||
```
|
||
|
||
### Ubuntu / Spark (`tun模式的主机mihomo config.yaml`)
|
||
|
||
本地 TUN 模式(`stack: system`),不依赖旁路由网关。设备重启后 `auto-route` 自建路由表,稳定可靠。监听器 `:7890` + `:7891` + `:7892`,节点直连 US-Direct。

|
||
### 第一部分:北京 VPS 配置
|
||
|
||
#### 1.1 Nginx Stream SNI 分流 `beijing-vps-stream.conf`
|
||
|
||
新增 `news.apple.com` SNI 映射(用于旁路由 Mihomo 直连代理):
|
||
|
||
```nginx
|
||
stream {
|
||
map $ssl_preread_server_name $backend {
|
||
www.apple.com xray; # 旁路由反向代理隧道
|
||
www.microsoft.com mihomo; # 外部客户端代理 → 东京出口
|
||
news.apple.com xray_lan; # 旁路由 Mihomo 北京直连代理
|
||
drive.salmonstill.cn nas; # 绿联云服务
|
||
default npm; # Nginx Proxy Manager
|
||
}
|
||
upstream xray { server 127.0.0.1:9443; }
|
||
upstream mihomo { server 127.0.0.1:9444; }
|
||
upstream xray_lan { server 127.0.0.1:9445; } # 新增
|
||
upstream nas { server 127.0.0.1:38653; }
|
||
upstream npm { server 127.0.0.1:8443; }
|
||
|
||
server {
|
||
listen 443 reuseport;
|
||
listen [::]:443 reuseport;
|
||
ssl_preread on;
|
||
proxy_pass $backend;
|
||
}
|
||
}
|
||
```
|
||
|
||
#### 1.2 Xray 配置 `xray-北京vps-config.json`
|
||
|
||
##### 新增入站 `proxy_from_lan`(北京直连出口)
|
||
|
||
```json
|
||
{
|
||
"tag": "proxy_from_lan",
|
||
"listen": "127.0.0.1",
|
||
"port": 9445,
|
||
"protocol": "vless",
|
||
"settings": {
|
||
"clients": [
|
||
{
|
||
"id": "113e167a-a2be-4b46-9010-60020108626c",
|
||
"flow": "xtls-rprx-vision"
|
||
}
|
||
],
|
||
"decryption": "none"
|
||
},
|
||
"streamSettings": {
|
||
"network": "raw",
|
||
"security": "reality",
|
||
"realitySettings": {
|
||
"show": false,
|
||
"target": "www.apple.com:443",
|
||
"serverNames": ["news.apple.com"],
|
||
"privateKey": "GGT9LfN_2JdQG68cwrULgUK-adfT6wIokLzWjaB0fXs",
|
||
"shortIds": ["7c947a71b94f369e"]
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
> Reality 公私钥复用已有的 `interconn` 入站 keypair,`serverNames` 用新的 `news.apple.com` 与 Nginx 对应。
|
||
> `target` 设为 `www.apple.com:443`,Reality 从此地址偷取真实 TLS 证书用于伪装。
|
||
|
||
##### 新增入站 `external_qbit`(BT 入站端口)
|
||
|
||
```json
|
||
{
|
||
"tag": "external_qbit",
|
||
"listen": "0.0.0.0",
|
||
"port": 51413,
|
||
"protocol": "dokodemo-door",
|
||
"settings": {
|
||
"address": "127.0.0.1",
|
||
"port": 51413,
|
||
"network": "tcp"
|
||
}
|
||
}
|
||
```
|
||
|
||
> 仅 TCP——Xray portal 反向代理对 UDP 支持不完善,BT 的 μTP(UDP) 走不了,需要在 qBittorrent 里关闭。
|
||
|
||
##### 新增路由规则
|
||
|
||
```json
|
||
{ "type": "field", "inboundTag": ["proxy_from_lan"], "outboundTag": "direct" },
|
||
{ "type": "field", "inboundTag": ["external_qbit"], "outboundTag": "portal" }
|
||
```
|
||
|
||
#### 1.3 腾讯云防火墙
|
||
|
||
新开端口:
|
||
|
||
| 端口 | 协议 | 用途 |
|
||
|---|---|---|
|
||
| 51413 | TCP | BT 入站 |
|
||
|
||
---
|
||
|
||
### 第二部分:旁路由 Xray SOCKS5 出站代理
|
||
|
||
#### 2.1 配置 `xray-旁路由-config.json`
|
||
|
||
qBittorrent 出站不走 Mihomo 透明代理,而是通过旁路由上 Xray 的 `socks-lan` 入站(`:1080`),直接转发到北京 VPS 直连出口。
|
||
|
||
##### SOCKS5 入站
|
||
|
||
```json
|
||
{
|
||
"tag": "socks-lan",
|
||
"port": 1080,
|
||
"listen": "0.0.0.0",
|
||
"protocol": "socks",
|
||
"settings": {
|
||
"auth": "noauth",
|
||
"udp": true
|
||
}
|
||
}
|
||
```
|
||
|
||
##### 出站 `to_beijing_direct`
|
||
|
||
```json
|
||
{
|
||
"tag": "to_beijing_direct",
|
||
"protocol": "vless",
|
||
"settings": {
|
||
"vnext": [
|
||
{
|
||
"address": "salmonstill.cn",
|
||
"port": 443,
|
||
"users": [
|
||
{
|
||
"id": "113e167a-a2be-4b46-9010-60020108626c",
|
||
"flow": "xtls-rprx-vision",
|
||
"encryption": "none"
|
||
}
|
||
]
|
||
}
|
||
]
|
||
},
|
||
"streamSettings": {
|
||
"network": "raw",
|
||
"security": "reality",
|
||
"realitySettings": {
|
||
"fingerprint": "chrome",
|
||
"serverName": "news.apple.com",
|
||
"publicKey": "62y5gDjPrdeuePGl-D2IW4Cw9Kb8_bSBBTmArvL7Nhs",
|
||
"shortId": "7c947a71b94f369e"
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
##### 路由规则
|
||
|
||
```json
|
||
{ "type": "field", "inboundTag": ["socks-lan"], "outboundTag": "to_beijing_direct" }
|
||
```
|
||
|
||
> 路径:`qBittorrent → SOCKS5 旁路由:1080 → to_beijing_direct → 北京VPS:443(SNI=news.apple.com) → proxy_from_lan:9445 → direct → 互联网`
|
||
|
||
---
|
||
|
||
### 第三部分:旁路由 Xray 51413 转发
|
||
|
||
#### 3.1 配置 `xray-旁路由-config.json`
|
||
|
||
##### 新增加出站 `to_qbit`
|
||
|
||
```json
|
||
{
|
||
"tag": "to_qbit",
|
||
"protocol": "freedom",
|
||
"settings": {
|
||
"redirect": "192.168.1.200:51413"
|
||
}
|
||
}
|
||
```
|
||
|
||
##### 新增路由规则
|
||
|
||
```json
|
||
{
|
||
"type": "field",
|
||
"inboundTag": ["bridge"],
|
||
"port": "51413",
|
||
"outboundTag": "to_qbit"
|
||
}
|
||
```
|
||
|
||
> 放在 bridge 下——从北京 VPS 的 portal 通过反向隧道过来的 BT 入站流量,由 bridge 接收后按端口 51413 匹配到此规则,转发到 qBittorrent 容器。
|
||
|
||
---
|
||
|
||
### 第四部分:NAS qBittorrent Docker
|
||
|
||
#### 4.1 创建 macvlan 网络
|
||
|
||
```bash
|
||
docker network create -d macvlan \
|
||
--subnet=192.168.1.0/24 \
|
||
--gateway=192.168.1.199 \
|
||
--ip-range=192.168.1.200/32 \
|
||
-o parent=eth0 \
|
||
qbit_macvlan
|
||
```
|
||
|
||
> `--gateway=192.168.1.199`:qBittorrent 的默认网关设为旁路由,确保出站流量经过旁路由。
|
||
> `--ip-range=192.168.1.200/32`:固定 IP。
|
||
|
||
#### 4.2 启动容器
|
||
|
||
```bash
|
||
docker run -d \
|
||
--name qbittorrent \
|
||
--network qbit_macvlan \
|
||
--ip 192.168.1.200 \
|
||
-e WEBUI_PORT=8090 \
|
||
-p 8090:8090 \
|
||
-v /path/to/downloads:/downloads \
|
||
lscr.io/linuxserver/qbittorrent:latest
|
||
```
|
||
|
||
#### 4.3 qBittorrent 设置
|
||
|
||
| 设置项 | 值 |
|
||
|---|---|
|
||
| 监听端口 | `51413` |
|
||
| UPnP/NAT-PMP | **禁用** |
|
||
| SOCKS5 代理 | `192.168.1.199` / 端口 `1080` |
|
||
| 连接协议 | **仅 TCP**(关闭 μTP) |
|
||
| DHT | 可选(建议开) |
|
||
| PEX | 可选(建议开) |
|
||
|
||
> 关闭 μTP(UDP):Xray portal 反向代理不支持 UDP,BT 的 μTP 走 UDP 会导致入站失败。
|
||
|
||
#### 4.4 定时做种调度(crontab)
|
||
|
||
让 qBittorrent 只在夜间(01:00-07:00)做种,白天暂停以节省带宽:
|
||
|
||
```bash
|
||
crontab -e
|
||
```
|
||
|
||
添加以下两行(在 NAS 或任意可访问 192.168.1.200 的设备上):
|
||
|
||
```
|
||
0 1 * * * curl -s -X POST "http://192.168.1.200:8888/api/v2/torrents/start" --data "hashes=all"
|
||
0 7 * * * curl -s -X POST "http://192.168.1.200:8888/api/v2/torrents/stop" --data "hashes=all"
|
||
```
|
||
|
||
| 时间 | 操作 | 含义 |
|
||
|---|---|---|
|
||
| 凌晨 01:00 | `/torrents/start` `hashes=all` | 启动全部种子开始做种 |
|
||
| 早上 07:00 | `/torrents/stop` `hashes=all` | 停止全部种子 |
|
||
|
||

|
||
|
||
### 第五部分:部署顺序
|
||
|
||
```
|
||
1. 腾讯云防火墙 → 开放 51413/tcp
|
||
2. scp beijing-vps-stream.conf → 北京VPS /etc/nginx/stream.conf.d/
|
||
3. scp xray-北京vps-config.json → 北京VPS /usr/local/etc/xray/config.json
|
||
4. 北京VPS: nginx -t && systemctl reload nginx
|
||
5. 北京VPS: systemctl restart xray
|
||
6. scp 旁路由的mihomo config.yaml → 旁路由 /opt/mihomo/config.yaml
|
||
7. scp xray-旁路由-config.json → 旁路由 /etc/xray/config.json
|
||
8. 旁路由: /etc/init.d/mihomo restart
|
||
9. 旁路由: /etc/init.d/xray restart
|
||
10. NAS: 创建 macvlan 网络 + 启动 qBittorrent 容器
|
||
11. NAS: 配置 qBittorrent 监听端口 51413,关闭 μTP
|
||
```
|
||
|
||
---
|
||
|
||
### 第六部分:验证
|
||
|
||
#### 6.1 SOCKS5 代理出站验证
|
||
|
||
```bash
|
||
# 在 NAS 上执行,应返回北京 VPS 的公网 IP
|
||
docker exec qbittorrent curl --socks5 192.168.1.199:1080 https://ip.sb
|
||
```
|
||
|
||
#### 6.2 Xray 日志确认
|
||
|
||
```bash
|
||
# 旁路由上查看 Xray 日志,确认 socks-lan 流量转发正常
|
||
tail -f /var/log/xray.log | grep socks-lan
|
||
```
|
||
|
||
#### 6.3 BT 入站验证
|
||
|
||
```bash
|
||
# 北京 VPS 上确认端口监听
|
||
ss -tlnp | grep 51413
|
||
|
||
# 从外部测试端口可达
|
||
nc -zv salmonstill.cn 51413
|
||
```
|
||
|
||
#### 6.4 端到端 BT 测试
|
||
|
||
下载一个热门 Ubuntu torrent 种子,观察:
|
||
- qBittorrent WebUI → 连接 → 应显示 DHT 节点数增长
|
||
- 跟踪器页面 → 应显示 "Working"
|
||
- 下载速度应有上传来确认入站工作
|
||
|
||
---
|
||
|
||
### 第七部分:故障排查
|
||
|
||
| 现象 | 排查 |
|
||
|---|---|
|
||
| qBittorrent curl ip.sb 返回真实 IP | SOCKS5 代理未生效,检查 qBittorrent 设置中代理配置 |
|
||
| 代理连不上 | 确认 旁路由 Xray 正在运行且 `socks-lan` 入站监听 :1080 |
|
||
| 入站无上传 | 检查北京 VPS ufw/腾讯云安全组已放行 51413/tcp |
|
||
| xray 报错 `reverse-proxy.xray.internal` | portal/bridge 域名不匹配,两边必须一致 |
|
||
| 下载有速度、无上传 | μTP 没关或 portal UDP 不支持,qBittorrent 设置仅 TCP |
|
||
|
||
---
|
||
|
||
### 第八部分:文件清单
|
||
|
||
| 文件 | 位置 | 作用 |
|
||
|---|---|---|
|
||
| `beijing-vps-stream.conf` | 北京VPS `/etc/nginx/stream.conf.d/` | Nginx SNI分流(含 news.apple.com → 9445) |
|
||
| `xray-北京vps-config.json` | 北京VPS `/usr/local/etc/xray/config.json` | Xray 入站+路由(含 proxy_from_lan + external_qbit) |
|
||
| `xray-旁路由-config.json` | 旁路由 `/etc/xray/config.json` | Xray bridge + to_qbit(51413) + socks-lan(1080) → to_beijing_direct |
|
||
|
||
## Minecraft UDP 转发
|
||
|
||
### 架构
|
||
|
||
```
|
||
公网玩家 (UDP 19132)
|
||
↓
|
||
北京VPS (salmonstill.cn)
|
||
socat 监听 19132 → 转发到 10.0.0.2:19132
|
||
↓ WireGuard 隧道
|
||
旁路由 ImmortalWrt (192.168.1.199 / 10.0.0.2)
|
||
nftables 端口转发 + SNAT
|
||
↓
|
||
NAS (192.168.1.188:19132)
|
||
↓
|
||
Minecraft 基岩版 Docker 容器
|
||
```
|
||
|
||

|
||
|
||
### 设备信息
|
||
|
||
| 设备 | IP | 系统 |
|
||
|---|---|---|
|
||
| 北京VPS | `salmonstill.cn` / `49.232.242.90` | Ubuntu 22.04 |
|
||
| 旁路由 | `192.168.1.199` / WG隧道: `10.0.0.2` | ImmortalWrt 24.10 (GL-MT2500) |

| NAS | `192.168.1.188` | 绿联云 UGOS |
|
||
|
||
---
|
||
|
||
### 第一部分:北京VPS 配置
|
||
|
||
#### WireGuard 配置 `/etc/wireguard/wg0.conf`
|
||
|
||
```ini
|
||
[Interface]
|
||
Address = 10.0.0.1/24
|
||
ListenPort = 51820
|
||
PrivateKey = <北京VPS私钥>
|
||
MTU = 1420
|
||
|
||
# 回包源地址转换(必须,否则公网玩家收不到回包)
|
||
PostUp = iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -o eth0 -j MASQUERADE
|
||
PostDown = iptables -t nat -D POSTROUTING -s 10.0.0.0/24 -o eth0 -j MASQUERADE
|
||
|
||
[Peer]
|
||
# 旁路由
|
||
PublicKey = 9jPlaUhx2Dc+C5ZqJx6Iu8GtNMig3cFIoqfHg8PZbCA=
|
||
AllowedIPs = 10.0.0.2/32
|
||
PersistentKeepalive = 25
|
||
```
|
||
|
||
> ⚠️ 不使用 iptables DNAT 转发,改用 socat 处理 UDP 转发,避免 conntrack 连接跟踪问题导致回包丢失。
|
||
|
||
#### 开启内核转发
|
||
|
||
```bash
|
||
echo "net.ipv4.ip_forward=1" >> /etc/sysctl.conf
|
||
sysctl -p
|
||
```
|
||
|
||
#### 开放防火墙端口
|
||
|
||
```bash
|
||
ufw allow 51820/udp # WireGuard
|
||
ufw allow 19132/udp # Minecraft 基岩版
|
||
```
|
||
|
||
#### 启动 WireGuard
|
||
|
||
```bash
|
||
systemctl enable wg-quick@wg0
|
||
systemctl start wg-quick@wg0
|
||
```
|
||
|
||
#### socat UDP 转发
|
||
|
||
socat 监听公网 19132 端口,收到包后转发给旁路由隧道 IP,并维护连接状态确保回包正确返回。
|
||
|
||
创建 systemd service:
|
||
|
||
```bash
|
||
nano /etc/systemd/system/mc-forward.service
|
||
```
|
||
|
||
```ini
|
||
[Unit]
|
||
Description=Minecraft UDP Forward
|
||
After=network.target
|
||
|
||
[Service]
|
||
ExecStart=/usr/bin/socat UDP4-LISTEN:19132,fork,reuseaddr UDP4:10.0.0.2:19132
|
||
Restart=always
|
||
|
||
[Install]
|
||
WantedBy=multi-user.target
|
||
```
|
||
|
||
启动并设置开机自启:
|
||
|
||
```bash
|
||
systemctl daemon-reload
|
||
systemctl enable mc-forward
|
||
systemctl start mc-forward
|
||
```
|
||
|
||
---
|
||
|
||
### 第二部分:旁路由 ImmortalWrt 配置
|
||
|
||
#### WireGuard 接口配置
|
||
|
||
路径:**网络 → 接口 → 添加新接口**
|
||
|
||
**常规设置:**
|
||
|
||
| 字段 | 值 |
|
||
|---|---|
|
||
| 接口名称 | `WireGuard` |
|
||
| 协议 | `WireGuard VPN` |
|
||
| 私钥 | `<旁路由私钥>` |
|
||
| IP 地址 | `10.0.0.2/24` |
|
||
| 监听端口 | 不填 |
|
||
|
||
**防火墙设置:** 加入 `wan` 区域
|
||
|
||
**Peers → 添加对端:**
|
||
|
||
| 字段 | 值 |
|
||
|---|---|
|
||
| 公钥 | `n159R7bNB+tW3Br0cok2zA27Pzg2WSPTI9uQ9odOFyU=` |
|
||
| 端点主机 | `salmonstill.cn` |
|
||
| 端点端口 | `51820` |
|
||
| 允许的 IP | `0.0.0.0/0` |
|
||
| 路由允许的 IP | ✅ 勾选 |
|
||
| 持续 Keep-Alive | `25` |
|
||
|
||
> ⚠️ 允许的 IP 必须设为 `0.0.0.0/0`,否则 WireGuard 会丢弃来自公网玩家 IP 的包。
|
||
|
||
#### 端口转发配置
|
||
|
||
路径:**网络 → 防火墙 → 端口转发 → 添加**
|
||
|
||
| 字段 | 值 |
|
||
|---|---|
|
||
| 名称 | `Minecraft-udp` |
|
||
| 协议 | `UDP` |
|
||
| 源区域 | `wan` |
|
||
| 外部端口 | `19132` |
|
||
| 目标区域 | `lan` |
|
||
| 内部 IP 地址 | `192.168.1.188` |
|
||
| 内部端口 | `19132` |
|
||
|
||
#### SNAT 配置
|
||
|
||
路径:**网络 → 防火墙 → NAT 规则 → 添加**
|
||
|
||
| 字段 | 值 |
|
||
|---|---|
|
||
| 名称 | `minecraft-snat` |
|
||
| 地址族限制 | `仅 IPv4` |
|
||
| 协议 | `UDP` |
|
||
| 出站区域 | `lan` |
|
||
| 目标地址 | `192.168.1.188` |
|
||
| 目标端口 | `19132` |
|
||
| 操作 | `SNAT - 重写为特定的源 IP 或端口` |
|
||
| 重写 IP 地址 | `192.168.1.199` |
|
||
|
||
> SNAT 的作用:将转发给 NAS 的包源 IP 改为旁路由 IP,确保 NAS 的回包发回给旁路由而不是直接走主路由,避免回包路径不对称。
|
||
|
||
---
|
||
|
||
### 第三部分:NAS Docker 配置
|
||
|
||
使用 `network_mode: host` 避免 Docker NAT 导致的 IP 映射问题。
|
||
|
||
```yaml
|
||
services:
|
||
bedrock:
|
||
image: itzg/minecraft-bedrock-server:2026.2.1
|
||
container_name: mc-bedrock
|
||
network_mode: host
|
||
stdin_open: true
|
||
tty: true
|
||
environment:
|
||
EULA: "TRUE"
|
||
VERSION: "1.26.14.1"
|
||
TZ: "Asia/Shanghai"
|
||
OPS: "2535472561115036"
|
||
volumes:
|
||
- /volume2/ProgramsV2/minecraft:/data
|
||
restart: unless-stopped
|
||
```
|
||
|
||
---
|
||
|
||
### 第四部分:验证
|
||
|
||
#### 检查 WireGuard 隧道
|
||
|
||
```bash
|
||
# 旁路由
|
||
wg show
|
||
# 正常应有 latest handshake 和双向 transfer
|
||
```
|
||
|
||
#### 检查 socat 运行状态
|
||
|
||
```bash
|
||
systemctl status mc-forward
|
||
```
|
||
|
||
#### 抓包验证完整链路
|
||
|
||
```bash
|
||
# VPS 上抓 wg0,确认双向流量
|
||
tcpdump -i wg0 udp port 19132 -n
|
||
|
||
# 旁路由抓 br-lan,确认转发到 NAS
|
||
tcpdump -i br-lan udp port 19132 -n
|
||
|
||
# NAS 上抓包,确认收到并回包
|
||
sudo tcpdump -i bridge0 udp port 19132 -n
|
||
```
|
||
|
||
---
|
||
|
||
### 故障排查
|
||
|
||
| 现象 | 排查方法 |
|
||
|---|---|
|
||
| WireGuard 无握手 | 检查 VPS 防火墙 51820/udp 是否开放 |
|
||
| socat 收不到包 | 检查 ufw 19132/udp 是否开放 |
|
||
| 旁路由收不到包 | 检查 WireGuard AllowedIPs 是否为 `0.0.0.0/0` |
|
||
| NAS 收不到包 | 检查端口转发内部端口是否填写正确 |
|
||
| NAS 有回包但玩家连不上 | 检查 SNAT 规则是否生效,确认 NAS 用 host 网络模式 |
|
||
| 游戏内延迟不显示 | 检查 socat 是否正常运行,DNAT 规则是否已删除 |
|
||
|
||
---
|
||
|
||
### 扩展:新增其他 UDP 服务
|
||
|
||
1. VPS 新建一个 socat service,修改端口号
|
||
2. 旁路由 LuCI 端口转发新增一条规则
|
||
3. `ufw allow <新端口>/udp`
|
||
---
|
||
|
||
## SOCKS5 动态 LAN 端口访问
|
||
|
||
通过新增的 `socks-dynamic` 入站(`:38658`,密码认证),可从外部访问任意内网 IP:PORT,无需事先配置端口规则。
|
||
|
||
```
|
||
浏览器 SOCKS5 → salmonstill.cn:38658
|
||
→ 北京VPS socks-dynamic → portal → 反向隧道
|
||
→ 旁路由 bridge → catch-all direct → 任意 LAN IP:PORT
|
||
```
|
||
|
||
---
|
||
|
||
## Reality 密钥
|
||
|
||
| 位置 | Private Key | Public Key (客户端用) |
|
||
|---|---|---|
|
||
| **北京 VPS**(3 个入站共用) | `GGT9LfN_2JdQG68cwrULgUK-adfT6wIokLzWjaB0fXs` | `62y5gDjPrdeuePGl-D2IW4Cw9Kb8_bSBBTmArvL7Nhs` |
|
||
| **搬瓦工 VPS**(客户端直连) | `iBlu3eH1VLf1S5Qw87m_1w0TGYUktDwHAzgpQ2aKuGI` | `jr_zQjC4mvlQITuG5Ap5Mxqe5EBbGyyvwbVLDEi8OCA` |
|
||
|
||
`Beijing-Direct` 节点必须 `skip-cert-verify: true`,因 Reality 返回 target(`www.apple.com`)的证书,而 SNI 是 `news.apple.com`,TLS SAN 校验会失败。
|
||
|
||
---
|
||
|
||
## 流量路径
|
||
|
||
### 路径 1:内网服务反向代理
|
||
```
|
||
用户 → salmonstill.cn:端口 → dokodemo-door → portal → 隧道 → bridge
|
||
→ 端口匹配出站 → 内网目标 → 原路返回
|
||
```
|
||
|
||
### 路径 2:代理翻墙(直连搬瓦工)
|
||
```
|
||
Mihomo 客户端 → 173.242.118.60:443 (SNI=www.microsoft.com)
|
||
→ Nginx 分流 → Xray :9443 → freedom → 互联网
|
||
```
|
||
|
||
### 路径 3:qBittorrent 代理出站
|
||
```
|
||
qBittorrent → SOCKS5 旁路由:1080 → Xray to_beijing_direct
|
||
→ salmonstill.cn:443 (SNI=news.apple.com) → proxy_from_lan → direct → 互联网
|
||
```
|
||
|
||
### 路径 4:BT 入站
|
||
```
|
||
BT Peer → salmonstill.cn:51413 → portal → 隧道 → bridge → to_qbit → 1.200:51413
|
||
```
|
||
|
||
### 路径 5:Minecraft UDP
|
||
```
|
||
公网玩家 → salmonstill.cn:19132 → socat → WireGuard → 旁路由 → NAS :19132
|
||
```
|
||
|
||
### 路径 6:SOCKS5 动态回家
|
||
```
|
||
浏览器 SOCKS5 → salmonstill.cn:38658 → socks-dynamic → portal → 隧道
|
||
→ bridge → catch-all direct → 任意 LAN IP:PORT
