Limit bandwidth to all internal IP addresses

    I have a Comcast cable line connected to a few Linksys WAPs, and there are users who are flooding out the entire line with P2P networking I would assume and the line is extremely slow at times. I need to be able to limit each internal IP address to only take up a portion of the line. I was basically thinking since the line is 6000/1000, I would limit each IP address to a max of 750/150 or something like that. For the line to flood, a lot of people would have to be doing things they should not be doing. Monitoring would be nice, but it is not required. Is this something DD-WRT can do easily with a Linksys WRT54GL? Anyone have experience on how I could accomplish this? Thank you!

    DD-WRT has a paid "special" version, which does exactly what you want.
    Other than that - the free tool Robson's WRT54G script generator will generate you a firewall script, which will do the same thing, with any 3d party firmware.
    You should also enable QoS.

    I have the paid version of DD-WRT. It allows to enter a netmask which I did and then it only lets me put in a max Kbits. What is this value? Does it limit the enter subnet to that value, or does it limit each IP address to the value? So if I have 5 people connected and that value is 150 kbits, does each get 30 for a total of 50 or do each get 150 for a total of 750?

    Also, the script is nice but it only allows for 32 internal IP addresses and I am not exactly sure how to edit the script for the entire internal subnet.

    Can anyone help out here? Thank you!!!
