Hi Thanks for your response. I am able to get the traffic redirected to my proxy server port. But the whole behavior is as if the tproxy kernel patch is not applied. In other words, on the web server I see that the request is coming from my proxy server and not from the client. The client IP is not getting rewritten. Any help is much apprciated. thanks again, Jojy ----- Original Message ---- From: "tproxy-request@lists.balabit.hu" <tproxy-request@lists.balabit.hu> To: tproxy@lists.balabit.hu Sent: Monday, August 13, 2007 3:00:05 AM Subject: tproxy Digest, Vol 26, Issue 11 Send tproxy mailing list submissions to tproxy@lists.balabit.hu To subscribe or unsubscribe via the World Wide Web, visit https://lists.balabit.hu/mailman/listinfo/tproxy or, via email, send a message with subject or body 'help' to tproxy-request@lists.balabit.hu You can reach the person managing the list at tproxy-owner@lists.balabit.hu When replying, please edit your Subject line so it is more specific than "Re: Contents of tproxy digest..."

Hi all 3. I have verified my changes by creating a REDIRECTION rule in the tproxy chain (can list my iptable changes by doing "iptables -t tproxy -L")
Hello, For instance a client try to connect to a webserver somewhere on the Internet listening on port 80, and your proxy is listening on port 50080. The iptables rule that redirects packets to that port is the following: iptables -t tproxy -p tcp --dport 80 -j TPROXY --on-port 50080 The next one is to allow incomming traffic on that port. Because the TPROXY target marks the packet, the following rule accepts these packets: iptables -t filter -A INPUT -m tproxy -j ACCEPT A tutorial is available here: http://www.balabit.hu/network-security/zorp-gateway/gpl/tutorial/ -- Regards, Laszlo Attila Toth ------------------------------ _______________________________________________ tproxy mailing list tproxy@lists.balabit.hu https://lists.balabit.hu/mailman/listinfo/tproxy End of tproxy Digest, Vol 26, Issue 11 ************************************** ____________________________________________________________________________________ Choose the right car based on your needs.
