Hi, I am using my machine as a Bridge and running transparent proxy on it. My question is - where the brdige will work? Do brdige will forward the packet before it reaches to iptables rule? If yes then what is the solution - as I want to use my machine as Transparent proxy and I have setup iptables rules on it. I have tried so many times - look at the tcpdump also - but it seems that packets are not following iptables rule and just being forwarded normally. Config is : FTP server - 192.168.11.160 Bridge - 192.168.11.201 I have setup jftpgw FTP transparent proxy on bridge. Which listens on port 2370. I have set a iptables rule iptables -t nat -A PREROUTING -p tcp -d 0/0 -s 0/0 --dport 21 -J DNAT --to 192.168.11.201:2370 Now I am trying to access FTP Server (192.168.11.160) from out side - and checking the tcpdump on the Brdige (proxy) machine for port 2370 - but nothingis coming up. Also on FTP machine the tcpdump shows direct connection. So it seems my transparent porxy is not coming in between and bridge is directly forwarding packet. What is the solution to this problem? Thanks, Tejas
