Hi Helge and all.

I could only see output regarding 'eth0', but it seems that more
interfaces are involved. I had a simiar problem at my place, and the
only advice I can give is that you guys need to check your entire
routing structure.
It is impossible for us (i.e. me) to give an answer based on on half the
truth.
Make sure that you haven't made the misstake to route through several
interfaces that don't have the conectivity required.
