There is a patch for that somewhere in ecos-patches, probably in the
last year. Although it looked O.K. i was not convinced it would work
in all situations. Why did the original author of the DHCP client not
do something similar?. I don't have a dual interface device so i
cannot test. So i would be interested in your comments about the
patch.
