The router that comes with my ISP contract is garbo and I highly doubt it has bridge function. With my used 60euro worth fritzbox, I keep the customization options and reliability. It has been 1.5 years and it hasnt failed me a single time while the other constantly had issues with stuff connecting to it.

My ISP changes IP somewhere around once a month. I own a domain on porkbun and they offer a simple docker compose script that updates my records to a current IP.
I believe other domain selling platforms also have similar scripts or solutions.
