Need help locking down my QoS

[tidehunter]

I often play online video games and latency is a must.
I've set Untangle v13 to:
"Bypass rules" and "QoS rules" to the ports i require and set the priority to "Very high", just like a VoIP phone.
I've set my "WAN Bandwidth" to 90%" of my connection.
From what i understand if i "bypass" the traffic i can improve the latency since the traffic isn't being processed by any of Untangles filtering apps?

So...
I begin a download using my browser over port 443(set to "Medium" in Bandwidth Control), so far my game latency is fine and seems to be unaffected.

Now i begin the same download, but instead of using my browser i use a windows application called Internet Download Manager (which oddly enough Untangle seems to identify it as IDM), i set it to download 8 streams at once per file, then my latency in my game sky rockets and my gaming experience is affected.

I guess its the same theory behind torrenting, torrents can have 1000's of sessions happening at the same time, on a consumer router a typical torrent client could cripple it, even if you cap the speed of the torrent at the router level, its still requesting all those sessions and the rest of the traffic is stalled.

Anyway, I can just set IDM to use 1 stream, problem solved, but is this possible to solve on Untangle? there are people on my network who also use IDM.
Is there anything i'm missing in my configuration or some method i can use to prevent a application flooding so many streams at once?

In your rack for Bandwidth Control could you create a rule using "Application Control: Application" is "IDM" then you can "Set a Priority" (or one of the other options)?

Something to try ...

Yes, I would just add a rule to priority IDM as "Low"
Also make sure you are using fq_codel as the "Queue Discipline"

Make sure your WAN limits are set correctly.

problem solved, in the end i had to use the setting "Limited" which i believe uses 75% upload / 75% download
i'll try and fine tune the "Limited" setting so its say 90%.
even at the "Low" setting, IDM can still for some magic reason fully cap out my internet, even with my other rules set in place, it will still try dominate the 100% of the net.

thats how "Low" works by default and probably how you want it to work.
You want downloads to be as fast as possible unless there is something more important.
You gain nothing by not using bandwidth - its just wasted.
