I have Covad dual/bonded T1 service in our office coming through a Cisco 1841 and then through a Sonicwall 3060Pro/Enhanced SW firewall.
The problem I'm looking for some input on is how to limit the amount of bandwidth any single user/PC can user for downloading a file from the Internet.
It's become an issue that when one person happens to download let's say an ~300MB file, normal internet access for the other employees slows to a crawl. I've seen through MRTG that in fact usage of the circuit jumps to the full 3mb for the duration of the download and then drops.
Is it possible to control this? I'm not familiar with QOS or the like so I'm not sure.
Any help on this would be appreciated.
