Gracias.
Yes, that's correct. WiFi is turned off on T-Mobile Gateway + it's connected to Asus RT-AX86U 2.5G port, Motorola cable modem for XFinity is connected to ASUS router Wan port. In Dual WAN setup T-Mobile is selected as main Wan, Xfinity as fail-over + fallback checkbox selected (using 5sec ping to google as connection check). When I disconnect T-Mobile Gateway form Asus router XFinity cable kicks in within 10sec, connecting T-Mobile Gateway back makes Asus to fallback to T-Mobile within 10sec.
For anyone attempting to access self-hosted services while outside your home network, I'd strongly recommend using Cloudflare Tunnels. The service is free and doesn't require any port forwarding or having to punch holes in firewalls. You run the cloud tunnel service on your local network adjacent to the services you're trying to reach remotely and it creates a secure tunnel to their cloud platform where you can create host names and setup extra verification steps to add a layer of security so that only you can reach your services remotely. There a number of good YouTube tutorials for doing this. Here's one:
