OpenWRT WiFi Bridging when WDS does NOT work

The below 'configs' work on a Cudy AP3000. It has a single Wired LAN Interface. And after double checking the same MAC Address is either assigned at a hardware level to both the Wired and Wireless Interfaces, or OpenWRT's drivers for this device do it during start up.

And yes, that's not a typo for all those duplicate IPs on all those interfaces shown below in /etc/config/network. It was the best way to make it work. OpenWRT doesn't have an issue with it, plus as noted, there's only one MAC Address on the device, so it really doesn't matter.

OpenWRT 25.10.5 was used in early 2026.
