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:
- Check OpenClash status, ensure subscription and nodes are working.
- Confirm Wi-Fi clients are properly routed through the firewall.
- 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:
- Make N1 the main router.
- 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:
- Check that N1 itself can access the proxy using the OpenClash dashboard.
- Verify Wi-Fi clients are in the LAN and properly receiving DNS and gateway.
- 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.
- 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.
