Hello everyone

i have a problem in my transparent proxy test,
i recently made up the testbed as below to run the tproxy patched
apache proxy [mod_proxy],
and i applied all iptables and routing rules with referencing the
readme file [http://www.balabit.com/downloads/files/tproxy/README.txt,
the proxy server listening the port 3128 and i checked there were no problem.
but  when the client tried to connect the web server,
the packets reached to the box and i found the usage counts of filter
rules in the mangle table incresed
but my tproxy server could not receive any corresponding packet from the socket

I want to know why my proxy server can't receive any packet through the socket,
Do i need some more DNAT rules ?
