Hello,

I post this question in hope that someone can answer it. I have an 384/64 
ADSL connection to the internet and sharing it for 4 computers. I would 
like to have some control over the downlink per host basis, e.g.: 60% of 
bandwidth to machine A, and 20-20-20% to machines B, C and D. I have been 
researching this subject, read about packet marking, qos, advanced routing, 
but all these things do not help me any further as its too late to mark 
incoming packets after they've arrived to my router... they've already 
flooded my downlink. I don't have the option to set up some qos on the 
routers on my ISPs side either, so I do not think that a qos solution 
exists for this issue.
So, the soluton I've been thinking of was a way to manipulate the outgoing 
tcp packets. If I could find a way to rewrite the outgoing ACK packets so 
that they are delayed or have a smaller window size than the one the 
original, masqed machine requested, maybe the host on the internet side 
would send slower, e.g. I could control the incoming tcp channel by 
controlling the outgoing acks. Do you know any tool/way to archieve this? 
Has anyone researched this subject, or have a better idea to have control 
over the incoming bandwidth?

Regards: Marcell
