https://hg.9grid.fr/plan9-nat/ I did a NAT implementation some times ago. It's working, but it's still an early work and I haven't worked on it for few months. It is implemented in ipifc, directly in the kernel IP stack. I attempted different implementations as kernel devices or user process, but I haven't achieved a satisfactory result yet. This URL is the development repository and I should probably extract a proper patch from it. See the README file for more details. I hope to have more time in the future to work on it. -- David du Colombier
