I know you can create an AppCtrl rule to limit application traffic by specifying the hours or time period in which the rule is active (Next Generation Security Gateway R80.10 Guide). However, I don't see an option to limit the duration of the traffic by number of hours, minutes etc., i.e. how long a particular application should/can be allowed through. I'm trying to limit video streaming on my network for certain user groups regardless of time of the day or week. How can I achieve this?
