cd /Volumes

This is the location of all mounted drives, including CDs, DVDs, USB Hard Disks, Flash Drives and even Mobile Me’s iDisk – they should all be available as folders below “/Volumes”.

  • Open up a session on OSX as the Administrator (I did this in parallel to my existing login).
  • Open up Terminal.
  • Type: 
    sudo ipfw pipe 1 config bw 45KByte/s

    This sets up the rule limiting your bandwidth.

  • Type: 
    sudo ipfw add 1 pipe 1 src-port 80

    This enables the rule.

Once you’ve finished the downloading you wanted to limit you’ll need to flip back into the administrator profile and do this…

  • Type: 
    sudo ipfw delete 1

    This deletes the rule.

If you have any questions, feel free to leave a comment. Please note that this only restricts Port 80 which is the general web traffic port, if you had other activity going on (Skype, Bittorrent) then you’d need to add a rule for each relevant port.
