Hi! In my network there's a recurring problem: people who sync their datas with cloud services like iCloud, Google Drive, Drop Box or similar occupy the whole upload bandwidth and they hang the whole network!
The easy solution would be limit upload speed for each application, but it can't be done for every user, and some services do not have the ability to throttle the upload (i.e. iCloud on iPhones/iPad).
The best solution would be to create some kind of firewall rules to give a low priority to the upload traffic to this services.
In my opinion this could be achieved via layer7-protocol, but I really don't have a clue on the regex to use to identify them.
Can anybody help me?
Thank you very much.
