How to setup mwan3 on OpenWRT?

Technical Support for Routers

I want my traffic going through USB-tethering, while destination to 192.168.0.0/24 going to WAN port. I have SSH-ed into the GL-AR750S and opkg-install-ed luci-app-mwan3. Both interfaces are up and accessible to the Internet. However, there is no network access (LAN or Internet) when the 0.0.0.0/0 default rule is set going through tethering_only.

This is too complicated. maybe just use static routing. But I am not sure how to set up.

I wanted to use static routing, but I am not sure if it could do the job. And I have no idea what the “route type” (unicast, multicast, etc) means.
