Yes, it is!! Awesome. From the README.txt file, I was of the opinion that the kernel needs to be patched and compiled.<div><br></div><div>I have the following scenario:</div><div><br></div><div> All UDP packets <b>coming in and going out</b> of port 5060 need to be redirected to port 56789. An application running on port 56789 must parse them, modify them and send them to their intended destinations. I must take care that packets coming from remote machine to local machine:5060 are FIRST received at local machine:56789, and then, after modification, sent to local machine:5060 with a spoofed header suggesting that it came from remote machine.</div>
<div><br></div><div>The incoming packets can be handled by this rule:</div><div><div> iptables -t mangle -A PREROUTING -p udp --dport 5060 -j TPROXY --on-port 56789 --tproxy-mark 0x1/0x1</div></div><div><br></div><div>
How should I handle the outgoing packets for 5060? Mangle table's OUTPUT rule does not take tproxy as a target.</div><div><br></div><div>Thanks for your reply.</div><div><br></div><div>--SM.<br><br><div class="gmail_quote">

TProxy is built into the kernel in 10.04.<br>
