I recently purchased the Slate 7 and I am loving it! I am getting performance that far exceeds my expectations. However, I have a non-standard use case and I am looking for guidance. My main WAN is over ethernet, and I have a cellular modem connected via USB. I would like to have WAN failover to the cellular connection if/when ethernet goes down, but I have a low data cell plan and would like to only allow IOT devices on this connection. I assume it involves utilizing the LuCI control panel, and a plugin. But I am new to OpenWRT and would greatly appreciate some advice on this!
Hi,
You can achieve this by installing the luci-app-mwan3 package.
For detailed configuration and policy examples, please refer to the OpenWrt documentation:
Before using mwan3, make sure to disable the router’s built-in multi-WAN management service to avoid conflicts:
/etc/init.d/kmwan stop
/etc/init.d/kmwan disable
After that, you can configure your WAN interfaces and policies via mwan3 in LuCI.
