Yes and no: given I use this laptop at two locations, the wireless IP
changes. At home, I can set it as it is indeed my own network, but not
at work.... :(

Actually you are right, I will have to do that as this morning at work,
the setup didn't work :( I have wifi and ethernet both at work and at
home, and though my tests seemed to work at home with my personal DHCP
they stopped at work for some reason. I will therefore try and find some
dhclient option preventing the setting of a default route for an0.
However when my ethernet is down (which does happen), I have to have a
default route available through an0... Gee, this is tough... :( Why is
it so easy with Windows ?

I will do some testing...
