This is within Parental controls. What does it mean? I didn't disable NAT Acceleration for my AC68U. Do I need to disable it for my AX88U? Thanks.

It comes down to speed versus features. If you want high speeds (over 150Mbps) on your router do NOT disable NAT Acceleration. There is a brief discussion here:
https://www.snbforums.com/threads/question-about-nat-acceleration-with-asus-88u.54236/

However, if you use NAT Acceleration, the Time Scheduling feature will not be fully functional - you won't get precise scheduling control. How imprecise? Basically you can't set a schedule for a client within Parental Control Time Scheduling, you can only Block a client.

On our routers it has to do with CTF (Cut Through Forwarding) which is explained here:

Thanks for the information above. Does it mean I have to disable all acceleration? Right now only "Runner" is disabled but "Flow Accleration" is still enabled.

I have an RT-AC5300 and I don't have that option. I opted for speed so NAT Acceleration is set to Auto (my choices are Auto and Disable). As seen below the NAT Acceleration option is in the LAN section.

I am also going to experiment this weekend with a two router setup to get the Time Scheduling feature to work and not sacrifice speed across my whole LAN (more info here https://www.snbforums.com/threads/rt-ac5300-parental-controls-and-high-speed-internet-fail.63384/)

I have Time Scheduling on my AX88U activated - it works without any problem - and accurate - WITHOUT disabling NAT Acceleration

Given how NAT Acceleration works (according to links above) that is interesting. I was actually thinking about upgrading to an AX88U since the four core processor (Broadcom BCM49408) is huge upgrade over what most of the AC class routers have. My thought was that the faster CPU (and more physical memory) would not need NAT Acceleration and that it could keep up with the 1 gigbit speeds. Perhaps Asus changed something with regards to the AX routers or the Trend Micro engine got an upgrade specific to the new class of routers.

Adaptive QOS and AI Protection works with NAT Acceleration but I do find it turned off if you need to limit bandwidth to specific devices
