Re: [tproxy] tproxy routing issue within processes in the same machine

Hi, IIRC it doesn't work for local connections/sockets, as it can't reroute outgoing packets to the local interface. On Sun, 2012-07-29 at 06:30 -0700, Ming-Ching Tiew wrote:

tproxy has problem working within 2 processes on the same machine, ie a client process using tproxy to spoof an IP, has problem communicating with the server process within the same machine.

It seems tproxy attaches itself to mangle table PREROUTING chain, that is unable to hook to the in-machine process. I figured that for it to work, in this case, it needs to be able to attach itself to the INPUT chain. However that hook is not supported.

Is there a way to get around this problem ?
