QoS change = broken internet

JOKER_ZA

Hi. Hope I'm posting in the correct group..

I'm trying to change the up and down speed of the external NICs QoS rule. When I make the change, I have no internet connection. Turning the QoS of for that interface has the same effect. Looking at the firewall log, there are a lot more blocks taking place than usual. DNS is also getting blocked then.

Reverting the QoS settings gets the internet back and stops the DNS blocking in the firewall. I am however getting packet loss when doing a ping test from the utm to and external IP. Upload speed is also horrible.

I've tried different NICs (Intel), different cables and disabling every protection feature I could find, but nothing helps

    Please show a picture of the Edits of the QoS Interface and rule that works.  Also show a picture of the change you made that blocks connection.

    Cheers - Bob

    I've managed to get the settings changed now. First had to turn off the QoS interface, change the settings, turn off the actual interface under Interfaces and wait 1 minute, then turn the interface back on and then turn the QoS interface on. 

    I don't know if it's repeatable. Since I finally got it changed I don't want to test that right now.

    One thing I did notice is that when changing QoS settings, the loading/activity indicator ring at the top of the interface stays active and never stops. Maybe some process getting stuck, or just a glitch in the interface?
