Hi guys

I have a Fritz!Box 7390 router connected to a 15-port switch which then goes off to various clients around the house -- one of them is a Blu-Ray player with DLNA in my Son's bedroom. The router has the ability to restrict certain network applications at particular times of the day and I'd like to use it to restrict him from watching movies over the network beyond his bedtime.

There are pre-existing network application templates like BitTorrent etc that you can apply, but you can also create new ones. The trouble is I don't really know what to enter and googling it just confused me more. Here's a screenshot of the form, does anyone know what I should enter to block DLNA? Cheers!
