Hi, Basically I am facing the exact same problem as shown in the discussion below: http://old.nabble.com/Content-Filter---Advanced-td20119772.html
I don't know how the OP solved the problem eventually, but I have even tried to set net.ipv4.tcp_window_scaling = 0 (some googling suggested that the timeout might have to do with this parameter), too bad I am out of luck. Any idea? Thanks in advance. -jan
