IP address from the router remains local even after connecting it to the modem in DMZ mode.
Your setup involves multiple devices and configurations. You're using a router connected to your ISP modem, with a LAN and WAN interface. The router is assigned an internal WAN IP, but you want it to show the public IP from your dynamic connection. The AC-88U appears to be receiving a static internal IP instead of the public one. Check if the router's DHCP settings are correctly assigning the external IP when connected to the internet. Also, ensure that the DMZ setting on the ISP modem isn't interfering with the router's ability to resolve the correct WAN address. If you need the router to display your public IP, verify that the DHCP lease is active and properly configured for internet access.
Not yet. Should I leave DHCP Service and NAT enabled on the ISP-modem/router while turning them off only on the Asus-AC88U? I attempted to disable the service on the modem/router, but it caused the AC88U to lose internet connection.
Looking for a bridge setting on the ISP modem/router combo, which appears outdated in most ISP modems locally. Opting to purchase your own approved modem from your ISP’s list, register its MAC address with the provider, and avoid equipment rental charges. If it's only a standalone modem, you won’t need to worry about additional steps. Note that using the ISP’s VoIP service or similar features might restrict bridge mode or modem usage depending on your plan and their business model.
DMZ should be able to transfer the Dynamic IP from the ROOT AP to the AC88U, but it might require bridge mode for proper routing. The information you found suggests that even with a private WAN IP, DDNS won't function if the device is in a multiple-NAT setup.
DMZing handles most traffic but assigns IP addresses to connected devices. Consider using bridge mode for better visibility of the WAN IP in your ASUS router. Disabling DHCP and NAT on the ISP router and setting a static IP for the router below can help, along with port forwarding. Bridge mode is simpler and avoids feature restrictions from your ISP.

All routers include this security feature by default. Edit: I actually looked into it myself thanks.
Yes, when running ROOT AP in bridge mode, the AC88U WAN IP will display your public WAN address, not the internal one. If you choose not to use bridge mode, you won’t be able to use DDNS on the AC88U. Instead, you can connect to a service like NO-IP and have a PC client automatically detect and update the new IP to the host name.
