We're running 6.6.2 1300. When I use Gatekeeper on a non-WG machine, I go to extended networking and uncheck the "Enable Bandwidth Control", then click OK. If I go back into Extended Networking, the checkmark is on again.
If I go to the WG server and do the same thing, the setting "sticks" like it should. If I uncheck the setting on the WG server and OK back out, then go to the remote gatekeeper, I cannot turn it back on remotely. I have not tried any other settings to see if this behavior repeats itself, but found this as I was trying to briefly turn off this feature today.
