Setting it up to handle Steam Downloads?

Post by tals »

Has anyone managed to cover the steam download in the QOS rules

I tried using the download ports specified in here:

https://support.steampowered.com/kb_art ... -GLVN-8711

ie

TCP 27014 to 27050

But that didn't get caught, anyone any ideas or managed to do this?

So I think I have finally nailed this one down. The official ports steam uses in the FAQ are not the ports that the game downloads happen on.

The ports it actually uses are between 60000 to 64900 and if steam slows down on one of those ports it will switch over to a better port an pick up speed again.

So yesterday I tried to install 4 games and see what happens. The ports continually shifted and eventually my port rule was so big that it started affecting other programs that use these port.

The only thing that never seems to change is the remote hosts that steam uses for downloading their games. the IP is 162.254.192.12 through 19 or so. I have no idea exactly how many server they have in this range, so I made a ham fisted rule to take the first 128 addresses and throw them into my bulk traffic. like this 162.254.192.1/25

so in you download rule add this Source: 162.254.192.1/25 ( to your Slow or bulk traffic rule) in my case I limit this class to 500mbps. And now if anyone in the house is downloading a game, it wont affect anyone.

I wish I could put QOS on a timed schedule so that it turns off after I go to bed and back on when I get up.

just checked it again and it was back up to full speed. Appears to have changed IP ranges. This thing is hard to kill.
just changed it to this.

162.254.192.1/21

Valves ip range starts at 162.254.192.1 through 162.254.199.255

Unfortunately I don't think that is always going to work. They have many IP ranges for different countries and if you can't get any connection to your preferred, it will switch you until you do.

Also I thought steam downloads were a port 80?
