BR1 Mini WiFi WAN Bridge Mode?

I have a server looking for the IP address of an IP camera connected to a Max BR1 Mini LAN port which is connected to an AP One via a WiFI WAN connection. Normally I would just put everything in bridge mode but that doesn’t seem to be an option with the BR1 Mini. Am I missing something? Why wouldn’t there be a bridge mode or IP passthrough.

Gateway (10.27.12.1) ↔ (10.27.14.33) AP One ↔ (10.27.14.42) BR1 Mini (192.168.50.1) ↔ (10.27.12.223) IP Camera
