[LARTC] Proxy question

[Σταμάτης Κεκές]

 Hell everybody,
 Yesterday I faced a problem with the shaper I use. Here's my topology 
and I'll describe the problem later after the topology.


  10.0.1.0 /24                   10.0.1.100       eth0               
eth1    eth0 10.0.1.1  eth1

 Well this is the http and ftp traffic flow on my netwrok. Some of my 
users used to download huge files from the web.
 Is there any way to slow down specific IP addresses even if they conect 
through the proxy ??
 For example I want to slow down the requests made from 10.0.1.51 but 
only that host. If I apply a filter for that IP it does not make any 
sense cause in fact the proxy is making the connection for that host.
 Has anybody else faced this problem ?
 Any ideas or suggestions ?
