I dont have Nat Acceleration (ASUS RT-AX82U)

[chris134214]

My setting where it would be is Bonding/ Link aggregation instead of Nat Acceleration.

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.

Is there a complete list of “features” which, when enabled, would disable NAT acceleration on the newer generation of routers? I presume that QoS is incompatible with NAT acceleration, but is there anything else?

No.

What I know so far:

QoS - Bandwidth Limiter
QoS - Traditional QoS
QoS - Cake (in Asuswrt-Merlin)
Guest Network - Bandwidth Limiter
VPN - Wireguard (in Asuswrt-Merlin or 388 Asuswrt code)
Traffic Monitor - Per IP traffic (in Asuswrt-Merlin, older ARMv7 platform)

The last one is included for folks with older routers.

Thanks! That is very useful.

With wireguard enabled or disabled, the output of "fc status" is the same.

Which option should be "disabled" when wireguard is on?

 

[Tech9]

With wireguard enabled or disabled, the output of "fc status" is the same.

On some models now WireGuard works with FC enabled. The post you quoted was made before that. For your model since this firmware:

Well, that's good news.

Thanks for your explanation!
