Configure eero to use static WAN IP?

My ISP provides a static IP but I have to configure that in my network setup / router. I was not able to find where to do that in the eero app, and ended up putting an old wifi/router between the eero and the ISP and placing the eero in bridge mode. Old router has way more control options for setups such as this, and is doing Firewall, plus DCHP, internal IP reservations, etc.

I need to tell the eero what my static public IP is. 

Possible?
