Limiting traffic packetshaper

For a newbie like me its quite difficult managing bandwidth for whole office, i had try squid delaypools, but when someone use download manager, squid cannot identify to limiting current conection.
Many friend told me to use Mikrotik as packet sharper , but still had many time to learn.
Until i found Packeteer Packetshaper.
Wow, i cant belive manage internet bandwidth is quite easy, this new toy looks like know anything i want to do, it can manage internet bandwidth without interfering local bandwidth.
It quite easy to install, just put it as bridge between internet router and local switch. Whola!!! you can get the traffic that goes on your network.
As i using Packeteer 1700 series with two interface, and 10Mbps license. So i can manage internet traffic up to 10Mbps without interfering speed from my local user to intranet server. Simply connect in port to local network and out port to router.
When someone use download manager which can make simultaneous connection to internet they can limit each client, waw such a smart toys. ;
