Just to compile the solutions (and my final remarks), I can find:

1) Use Bridging
   Cons: I have to change my wifi card (to support promiscuous mode)
   Pros: Can change to a newer kernel; basic setting

2) Use normal routing
    Cons: I have to change my wifi router
    Pros: Basic settings

3) True NAT
    Cons: Possible, but very difficult (no answer at all there)
    Pros: Nothing to buy. Just system setup.

Then, I guess I will stick on trying (3) some time, and come back to
my first choice (1)
when I can find a good wifi card fully supported by the latest kernels...

Thanks a lot for your answers,

Bruno.
