OpenWrt as access point for open sense firewall

I have a open sense firewall and use a openwrt link sys router to get wifi to my devices.

Modem-> OpenSense->OpenWRT-(wifi)>Devices

Which works so far for my main wifi in the lan network but I have another network called iot24 which I do not really know how to route it though the openSense firewall. Any hints where I should start?

What I tried so far:
-Setting the open sense firewall as default GW in the iot24 network.
-sharing firewall rules in the openWRT device to allow traffic

Did you create the iot24 network on your OpenWrt router (as a new network), or did you create it on your pfsense box with the VLAN passing to the OpenWrt device as a dumb AP?
