I'm trying to setup dummynet for my home network. I have an 384/128kbps
ADSL connection to the Internet. What I want to do is give priority to a
100kbps video stream when it's running over other traffic. The video stream
comes from 192.168.1.3:8080 on my internal network. I setup the following
rules on my firewall:
# Begin Configure pipe & queues to allow video stream priority
# Flush before we define
$fwcmd -f queue flush
$fwcmd -f pipe flush
$fwcmd pipe 1 config queue 64Kbyte
$fwcmd queue 1 config pipe 1 weight 90 queue 56KByte
$fwcmd queue 2 config pipe 1 weight 10 queue 8Kbyte
$fwcmd add queue 1 ip from 192.168.1.3 8080 to any
$fwcmd add queue 2 ip from not 192.168.1.3 8080 to any
Now this seems to work as I don't get any errors when the rules load. I
also notice that I match packets when connecting to the video stream with
the first "add queue" rule. However other packets do not match the second
"add queue" rule and I don't understand why. I expect that every packet
crossing the firewall that is not part of the video stream to be added to
queue 2. What am I missing?
I would also appreciate any suggestions on tuning the queue size for my
purpose as I really don't have any understanding other than the defaults are
probably too large for my slow ADSL link.
Thanks for the help,
Drew
