Hello guys, I’m trying to block jdownloader with layer 7 pattern, but I dont know exactly know how to do it, so if you could give me a hand, I’ll apreciate it.
Thanks!
Jdownloader is simply a download manager, you can’t block it unless you block user completely from downloading any content from the internet 
Download managers usually opens many connections to speed up file downloading. Solution is to reduce connection count per user.
Thanks for your reply mrz. As I said before, I don’t know to much about layer 7, but with this method, is it posible to detect wich program is using the port and block it? I mean, don’t simply block the port but block the program wich uses that port.
Thanks for your consideration and sorry for my English, I’m from Argentina and I’m trying to do my best 
The router cannot have any knowledge of what process name on a client machine is responsible for a connection.
If the download managers are try to connect as many simultaneous connections to the one IP address,
So is it possible to max limit the number of connections to one IP address, or should it be by file type I.E. EXE,ZIP,..etc?
Not solution for HTTP Downloaders? anyone have a good script, pattern or something?
