Firewalla Gold -- Router mode Asus AImesh network -- missing nodes and devices

Set up my firewalla gold in router mode, asus rt-ax89x in APmode -- connecting to three asus nodes.  I can see the AX89x on the network -- cannot see any of the nodes -- although they are working.  I also have a number of devices although working appear as no IP assigned.  Any suggestions?  

In AP mode, the firewall, IP sharing, and NAT functions are disabled by default.
