[En-Nut-Discussion] DHCP client and losing UDP packets

That could have several causes, not easy to determine
by a single module. Did you check your application
code for infinite loops without NutSleep, NutEventWait
or similar?

You add a default route? Why? As far as I know, DHCP depends
on broadcasting, at least for discovery. But broadcasts are
not routed.

I checked the diff to the current CVS HEAD, but couldn't
find something else, what might cause the problem.
