This might be a long one but want to be clear and thorough.  My previous setup before I got the eeros was my ATT PACE 5268AC fiber gateway --> Asus AC68 (setup in DMZplus mode on the ATT PACE so it takes the WAN IP) --> 16port switch for other wired devices like other eeros, and other hardwired devices.  This allowed me to connect to WAN IP or the DDNS name even from the LAN side (like my iPhone on the wifi network, it could easily hit the DDNS name of my Network Video camera unit).

Now my setup is ATT PACE 5268 fiber gateway --> Primary eero --> 16port switch for other wired devices like other eeros, and other hardwired devices.

On my previous Asus AC68 router/gateway/wifi device we had the capability of adding a DDNS or Asus provided one, like mine was xxxx.asuscomm.com . So allows me to access my home server or network cameras without having to remember my WAN IP. Does eero not have a feature for this or is it in the plans for future release? If so when?

Secondly, being that I have network cameras and other smart devices like electricity monitoring apps on my smartphone, I had the smartphone apps look at that DDNS name like my Qsee Network cameras would point to xxxx.asuscomm.com to access the cameras. That worked remotely while I was on say a cellular LTE network or even inside the house. Right now that concept (here I use the public IP on the app) doesn't work inside the LAN network. Only works when Im on Cellular LTE (meaning the port forwarding and all that is correct). Seems eero from inside its LAN network doesn't know how to reroute itself via say my public IP or DDNS name to the server/device inside my network. Again Asus, Linksys, even Belkin routers had this capability. Ive been using this for 5-8yrs now.

Now I have no choice but to constantly change that address on the smartphone app if Im inside my house and when Im remote I need to use the public IP.

Or my only options is to put the Asus AC68 back in as the main router and let the eero sit in Bridge mode, but was trying to eliminate these devices and clean this up.
