oops while answering your email, I ifdown'ed eth0 just to make sure it
was up. I forgot to ifup'ed it back.

$ ip route show

This is a small ppc mac mini, connected to a freebox (french tivo). I
thought I could use eth0 for upnp (mediathomb), while having wlan0 for
remote ssh session from my laptop...

How do I configure prefered route ?

Thanks again,
