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. I think a Linksys WRT54GL with DD-WRT or Tomato firmware might do this, but I am not exactly sure how. Please post if you have experience doing something like this. I would also take other suggestions besides the Linksys as long as they are not too expensive. I need to do this with 5 cable lines, and I really cant spend much more than $250/line. Thank you!
