hello everyone, hows your day.
Iam looking for configuration to separate between Internet download manager (IDM) and streaming movie which both of them using same port 443 TCP.
Any advice from you guys ? If i can block IDM its better, so my plan is people can download while streaming movie
Big thanks.
No answer at all team?
Well, you have port 443, so most likely encrypted https. Router can’t tell what made the request, whether it was web browser, download manager, etc. If it would be different client devices, you could do something based on their addresses. But if it’s same device, or multiple, but doing all things, that’s out. If you know exact servers they use, you can play with tls-host. If you don’t, you could do something based on amount of data transferred by each connection. But how successful that can be, that’s a question. Streaming can have one connection with high amount of data, while download manager can split downloads into multiple connections with smaller amount of data. In short, it’s a challenge or hopeless endeavour, depending on how optimistic you are. 
yes until now i cant find good solution for this case 
Use different ports on the WAN site and forward them to port 443. I.e. port 50443 for download manager and 60443 for streaming service. Or is that to simple!?
Iam still learn and hope you can share your QOS about this case.
thank you for your reply, can you explaine more specific ? may be step by step for doing that
If you expect any solution from me, then I have to disappoint you, I don’t have any, sorry.
