Good one. I was trying all bases to get from one to another. Now I
feel silly :)

Another thing I noticed, is that there is no entry at all for mtu in:

/sbin/dhclient-script

Could this be the reason that the mtu does not get set? It seems that
all other values get set there: medium, netmask, IP , etc..

Thanks for all you help.

Andrew.
