I've rebuilt a kernel with the last patch available in the PR.
It doesn't work (return nat rule in place).

I think I'll try the following setup on gateway1 :
- IIPTran https://www.ietf.org/rfc/rfc3884.txt (ipip tunnel in transport
  mode)
- outside nat with pf on gif interface

What bothers me is that ipfw reverse nat should work...
