Hello TProxy patch is very convenience patch to make transparent proxy keeping source IP address. I think that tproxy is almost only solution to keep source IP address, at now. So, I hope that tproxy patch is included to the official netfilter/kernel release. I have asked to include tproxy to official netfilter/kernel release. But, they want that developer submit the patch like following. http://lists.netfilter.org/pipermail/netfilter-devel/2006-October/025812.htm... How do you think about merging tproxy patch to official netfilter/kernel release ? And, can you submit the patch to netfilter team, if possible ?
