NAT acceleration doesn't exist on the current generation of Asus routers. That was a hardware feature of the older "N" and "AC" models.

Not quite accurate. NAT acceleration still exists (it's now called flow cache, with the second level called packet runner or archer depending on the router model), however there is no webui option to manually enable/disable it. The firmware will automatically disable it when an incompatible feature is enabled.

The flow cache engine is much more sophisticated than the old CTF.
