Ensure a minimum bandwidth

[JohnConnor]

Hi,

I'm trying to setup traffic shaping on my pfsense, but i'm not realy sure if i'm doing it right.
Can you tel me if 'im in the right way ?

I've a basic firewall setup. One WAN and one LAN interface

I have in my LAN an audio streaming server (ip 192.168.66.196) and I want to have at least 500kbps of bandwidth for it in upload.

To do this I created a queue (see the attachments)
And after I made a floating rule with the following settings : "Action:Queue" "Interface:WAN" "Source:My server(192.168.66.196)"

I seen a lot of post on how to limit the bandwith for one host but not how to ensure a minimum bandwidth for one host

Thanks
