Hello there, I am a computer science student interested in Netfilter development. In my research, I need to do source NAT on the INPUT chain. My Linux kernel version is 2.6.18. This kernel does not have a INPUT chain where source NAT can be done. Basically, I want to change the source IP of the incoming packets on the INPUT chain. This sounds a little weird. But yes, that is what I need to do in my current research project. I am thinking that we may need to patch the Netfilter code of the 2.6.18 kernel to achieve my goal. That is not easy to do. So does anyone have any suggestion of how to do SNAT on the INPUT chain? I would greatly appreciate it if you can provide a patch to do that. Thanks for your help. Best, Steve Computer Science Dept.
