7621 devices include hardware NAT. And anything Qualcomm in the recent past does. Most home WiFi 5 and above routers can do hardware NAT just fine. Hardware NAT allows for using cheap and old cpus for CPE. ISP hardware is a different story. Some decent routers that can do that which don’t cost a lot.

Tell that to my fixed line provider, with their CGNAT ... And its just about every provider in Germany pulling that crap. O, and dynamic IPv6 pre-fix also, because can't have you run any servers!

Yes, plenty of ways to bypass it but when you have ISP's still stuck in 1990's attitude, with dynamic IPv4/IPv6, limited upload (1/3 to 1/5 of your download), etc ...
