Also I would like to mention another bug as I’ve noticed that auto channel is not working with WiFi. In my /etc/config/wireless file I use option channel ‘auto’ but the new mango always operates at channel 1 instead.
On the other hand the same option works well if I set an specific channel value, for instance option channel ‘6’
About the “Force all clients” option, the related script firewall.user is supposed to be executed on boot and firewall restarts but all indicates that in MT300N-V2 the script only runs completely in case of a firewall restart (not to confuse with firewall start or reload)
On the meanwhile (waiting for an update), a middle fix is adding the line ‘/etc/init.d/firewall restart’ to the /etc/rc.local file so as to force the firewall restart right at the end of the boot process.
I update my findings about the /etc/firewall.user script bug .
As this script is executed on boot by the fw3 -q start command in the /etc/init.d/firewall file then I removed the value “-q” that quiets the log feedback to see the execution during the boot process.
It seems that the fw3 start command is executed too soon as I got the following related errors in the log :

Conclusion : The /etc/firewall.user script fails to run on boot with MT300N-V2 because it is executed before the interface lan (device br-lan) is up and ready. Consequently the “Force all clients” option won’t work everytime the minirouter is rebooted
Note: The command fw3 reload which is called when lan is up (firewall hotplug) does not execute the /etc/firewall.user script by default
