N1配置了openclash服务,但通过N1的无线,无法科学上网

Troubleshooting OpenClash on N1 box

The user is using a N1 (likely Amlogic N1 box) with OpenClash on OpenWrt, but can't access the internet via Wi-Fi. I'll suggest a systematic diagnosis:

  1. Check OpenClash status, ensure subscription and nodes are working.
  2. Confirm Wi-Fi clients are properly routed through the firewall.
  3. Verify if N1 is in AP mode or router mode; OpenClash should be on the gateway if it’s in AP mode.

Diagnosing connectivity issues with OpenClash

If N1 isn't the gateway, client devices might still use the upstream router, bypassing OpenClash. First, make sure N1 is set as the main router, or route traffic through it. Also, confirm DNS is forwarded properly with OpenClash or clients use N1's DNS. Ensure firewall and iptables rules are set correctly, and consider DNS or proxy settings like Fake-IP vs. redir-host. Finally, check wireless bridging in OpenWrt to ensure clients can access the proxy.

Performing quick tests for OpenClash setup

To troubleshoot, first, check the Wi-Fi client's default gateway—ensure it points to the N1's LAN IP. Then, verify DNS settings by running nslookup on the client to confirm it's using N1’s DNS.

On N1, check OpenClash’s status with commands like logread -e openclash. Additionally, inspect routing and firewall rules for conflicts. Depending on OpenWrt version, ensure OpenClash supports nftables or enable compatibility mode for iptables. Also remember to check if bypass router features are enabled.

Diagnosing N1 Wi-Fi connectivity

It sounds like the main router handles PPPoE, with the N1 providing proxy services. Since the user can’t access the internet via N1’s Wi-Fi, there might be an issue with the Wi-Fi setup.

To troubleshoot, ensure the SSID is on the same LAN zone and N1 is set as the gateway.

In OpenWrt, check:

  • Add wlan0 to br-lan under interface settings.
  • Assign it to the "lan" zone, and ensure DHCP is enabled.

If using relay or WDS, ensure wireless is bridged to LAN, not WAN. Also, check NAT settings on the WAN interface and possible option mtu.

Structured troubleshooting for OpenClash and N1 Wi-Fi

To address the issue where Wi-Fi clients can't access the proxy, begin by ensuring client's traffic routes through N1. Check the default gateway, DNS, and run traceroute to confirm they're connected properly. If N1 is in "bypass" mode (旁路由), you have two options:

  1. Make N1 the main router.
  2. Set up static routes or direct client gateways to N1.

Ensure OpenClash is properly set up: check status, configuration, firewall, and DNS settings. Confirm both firewall zones and DNS are configured to route appropriately.

For quick fixes, you could restart OpenClash, update, and address port conflicts.

Troubleshooting OpenClash and WiFi Client Setup

To resolve the issue, follow this step-by-step:

  1. Check that N1 itself can access the proxy using the OpenClash dashboard.
  2. Verify Wi-Fi clients are in the LAN and properly receiving DNS and gateway.
  3. If N1 isn’t set as the gateway, explain setup options:
    • If N1 is the main router, ensure DHCP and NAT are enabled for LAN.
    • If N1 is a bypass router, make sure Wi-Fi clients connect through N1’s DHCP with the correct gateway. If N1 is in relay mode, confirm the bridging configuration.
  4. In OpenClash, ensure the “LAN” zone includes the Wi-Fi interface (wlan0). If it's not in the LAN zone, traffic won’t pass through OpenClash's proxies. Additionally, check compatibility with iptables if using newer versions of OpenWrt.

下面按最常见原因 → 最快验证方法 → 对应修复来排查。你这个现象(N1上装了 OpenClash,但“连上 N1 的无线”却不能科学上网)90% 都是 “客户端流量其实没走到 N1 的代理/转发链路”“无线接口没被 OpenClash/防火墙纳入代理接口”


1)先确认:连上 N1 Wi-Fi 的设备,默认网关是不是 N1?

在手机/电脑连上 N1 的 SSID 后:

  • 看 IP 信息:
    • 默认网关(Gateway) 应该是 N1 的 LAN IP(比如 192.168.1.1 或 192.168.31.1 之类)
    • DNS 最好也指向 N1(同一个 LAN IP)

如果默认网关不是 N1(而是上级主路由)
那 OpenClash 再正常也拦不到你这台设备的流量——因为你只是“连了 N1 的 Wi-Fi”,但网关不走 N1

修复思路(旁路由场景最常见)

你大概率是“主路由上网,N1 做旁路由/软路由”。要让连 N1 Wi-Fi 的设备科学上网,有三种任选其一:

  1. 让 N1 给 Wi-Fi 客户端发 DHCP,并把网关发成 N1(最简单)

    • N1 的无线接口要桥接到 LAN(br-lan)
    • N1 的 LAN 开 DHCP
    • 客户端拿到的网关= N1
  2. 不改 DHCP,在客户端手动把网关/DNS 改成 N1(临时验证最快)

    • 手机/电脑把网关改成 N1,看是否立刻生效
  3. 在主路由做策略路由/静态路由,把需要科学上网的客户端引到 N1(更“正统”的旁路由玩法)

    • 例如把某些设备 IP 的默认路由指向 N1

2)如果网关确实是 N1:重点看“无线接口有没有纳入 LAN & OpenClash 代理接口”

很多人无线能上国内网,但不走代理,是因为:

  • 无线 SSID 绑在了单独接口/Guest(或防火墙 zone 不是 lan)
  • OpenClash 只对 lan/br-lan 做了重定向,没包含你的 wlan 接口

你要检查这两处

A. OpenWrt 网络侧:无线是否桥接进 br-lan

在 OpenWrt:

  • 网络 → 接口 → LAN → 物理设置
    看看是否勾选/包含了对应的无线接口(wlan0 / wlan1,或“与 LAN 桥接”)

如果你的无线是单独建了一个接口(比如 wlan-guest),那它就不在 LAN 里。

B. 防火墙侧:无线接口所在 zone 是不是 lan

  • 网络 → 防火墙
    看无线对应接口属于哪个 zone:
    • 需要在 lan(或者至少在 OpenClash 被配置为“需要代理的接口/区域”里)

3)OpenClash 本体快速自检(确认它真的在工作)

在 OpenClash 页面确认:

  • 运行状态:OpenClash 服务运行中、核心已启动
  • 配置文件:已启用、订阅更新成功、有可用节点
  • 面板/Dashboard:能看到连接与日志滚动

你也可以在 N1 上 SSH 跑几个快检:

sh
logread -e openclash | tail -n 80 ps | grep -E "clash|openclash" | grep -v grep netstat -nlp | grep -E "7890|7891|9090|7874"

如果 7890/7891/9090 这类端口都没在监听,那就是 OpenClash 没真正起来(或端口冲突)。


4)DNS/IPv6 是第二大坑:表现为“能连但打不开/解析怪”

即使代理规则正常,DNS 没被接管也会导致“看起来像无法科学”。

建议做这几项(按常见有效组合):

  1. 确保客户端 DNS 指向 N1
    • 通过 DHCP 下发:LAN DHCP 里把 DNS 设为 N1
  2. OpenClash 里开启(名称可能略有差异):
    • DNS 劫持/重定向 53
    • 使用插件 DNS(或 Fake-IP/Redir-host 按你的配置)
  3. 先把 IPv6 关掉做验证(非常常见的“IPv6 直连漏网”)
    • OpenWrt:网络里先禁用 IPv6 RA/DHCPv6(或直接全局禁 IPv6)
    • 等确认 IPv4 代理 OK 再考虑开 IPv6 代理

5)如果你是 OpenWrt 22.03/23.05/24.xx(fw4 / nftables):注意防火墙模式兼容

新版本 OpenWrt 默认 fw4(nftables),有些情况下 OpenClash 规则没正确落地,会出现“服务在跑但不生效”。

处理方向:

  • 升级到较新的 OpenClash(以及内核 core)
  • 确认 OpenClash 的防火墙接管/模式设置正确
  • 必要时安装兼容组件(如 iptables-nft 相关)并重启防火墙

重启顺序可试: 1)停用/启用 OpenClash
2)重启 firewall
3)重启路由


6)给你一个“最快定位”的两步结论法

Step 1:看客户端默认网关

  • 不是 N1 → 直接按“旁路由网关/路由”修
  • 是 N1 → 继续 Step 2

Step 2:看无线是否在 LAN zone & OpenClash 代理接口里

  • 不在 → 把无线桥接进 br-lan 或把对应接口加入 lan(或 OpenClash 代理接口)
  • 在但仍不行 → 查 DNS 劫持/IPv6/防火墙兼容与 OpenClash 日志

如果你愿意把下面三项信息贴一下(截图/文字都行),我可以直接给出“你这台该改哪一项”的精确改法:
1)客户端连上 N1 Wi-Fi 后的 IP/网关/DNS
2)OpenWrt 里 LAN 接口的物理成员(是否含 wlan)
3)OpenClash 的 运行状态页(模式、代理接口/流量控制、DNS 设置那块)
