I am trying to add QoS and define the uplink/downlink to my internet interface. I have beenr unning the firewall for months now on v5.0 and about to install some VoIP hardware and want to define QoS settings. So when I go to edit the internet interface and add QoS up/down info. I get this error
Can't rename Interface
One of the predefined interface network definitions is still in used in network groups or packet filter rules.
Any advice, hints or info would be greatly appreciated!
Thank you in advance
