Monitor bandwidth usage for each computer in LAN

[Reuben D. Budiardja]

Hello,
I have a cable connection that come to my D-Link Combo (wired / wireless) 
router in my home network. There are three wired computers and one wireless 
laptop connected to the router right now. Is there any easy way to monitor 
the broadband bandwidth usage for each computer (ie. outgoing and incoming 
bandwidth) ? Can mrtg do this ? 

Thank you.
