[tproxy] Question about tproxy "connection source addres..."

Hello, Is it possible that tproxy works in following scheme: a) client_request goes from IP_Client -> b) tproxy/iptables intercept it and redirect it to proxy_server [ie. Squid] binded on IP_Proxy c) proxy sends request for client to reqested_addres but source IP isn't IP_Proxy but is [converted to] IP_Client. Reply is intercepted again and refined inversely... Could it be done in some way? Regards, tw -- PS. Please CC me in reply as I am not a list member. ---------------- ck.eter.tym.pl "Never let shooling disturb Your education"
