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
