NAT Is the Enemy of Low Power Devices

But it'd be trivial to tell it to free the device from it, unlike with NAT, where you pretty much have to expire sessions to not run out of memory.

Not if the end user isn't in control of the firewall. (And if they were, then they could just forward dedicated ports for the devices they need.) It might not be as bad as the CGNAT situation, but there are plenty of big WANs that can't be reconfigured at will.

I have firewalls in v4 and v6 networks which don’t do any natting (well other than some 6-4 between them). They track sessions for security purposes, and they time them out for both security and memory reasons.
